    ACI Iran Chapter Mortar Workability Competition
    Objectives

    While current ACI Iran Chapter competitions focus mainly on strength or hardened concrete performance, this competition will focus on workability and rheological properties of cement-based materials. Teams are challenged to create a mortar mixture with optimum flowability and stability. Students are to mix mortar at the convention competition site and their mixture will be poured into a mold made in the shape of the letters aci from the top of the letter “a”. Both flowability and mixture stability will be evaluated. In creating their mortar mixture, teams will have to pay careful attention to the specified material requirements just as concrete producers must meet specification and project requirements on a daily basis.

    Prizes

    First, Second, and Third place entries will each be awarded a certificate of recognition, will be recognized in ACI Iran Chapter’s newsletter if space allows, and will be recognized on ACI’s Iran Chapter website at www.aciiranchapter.org.

    Rules

    1. Eligibility

    a. The rules of eligibility have been translated to Persian and attached to this document.

    See attachment A.

    Each competition has separate and different requirements and rules of eligibility, so participants in the student competitions should read each document carefully.

    b. Since this competition involves mixing and pouring of mixture at the convention, it is required that at least two team members be present at the convention to participate in the mixing, pouring, and cleanup during the competition. Participation by additional team members is both permitted and encouraged, though a maximum of 4 students will be allowed to mix mortar in order to maintain a safe working area.

    c. Please note that previously for this competition there have been many teams disqualified due to non-compliance with the rules. Please review the rules carefully, taking special note of the allowable materials and requirements for aggregate composition and water content.

     

    2. Material

    All material requirements indicated below should be closely followed and all materials and the mix design used in the competition are to be clearly described in the Written Report (see Section 3). The mix design and cost calculation need to be submitted via email before 12 December 2019. The specific details can be found in Appendix A. Teams failing to do so will be either disqualified from the competition or will have a penalty applied, as determined by the judges. Special attention should be paid to the aggregate gradation requirements dictated in Section 2e.

    a. The mortar must use cementitious materials as binder, as defined in Section 2b below. A maximum of 30% of the binder material may be supplementary cementitious materials (by total mass of cementitious products).

    b. The cementitious materials shall be Portland cement meeting ASTM C150.

    Supplementary cementitious materials (up to 30% of total binder) such as fly ash and natural pozzolans meeting ASTM C618, silica fume meeting ASTM C1240, or slag cement meeting ASTM C989 may also be used. If no pure Portland cement is available in the region of the competing team, a blended cement may be used, provided the amount of SCM in the cement does not exceed the limiting quantity. Product information sheets must be included in the report. If the quantity of SCM is stated to be in a certain range, the maximum value shall be assumed for this competition. The cost of a blended cement is considered to be equal to the cost of a pure Portland cement.

    c. Mineral fillers such as kiln dusts and rock dusts are also allowed to be used provided the total substitution for Portland cement does not exceed 30%. Blended cement shall not be used, except if no pure Portland cement is available, as discussed in 2.b.

    d. Nano-materials shall only be used in aqueous suspensions. Those materials shall not be used in dry/powder form for safety reasons. A water content of 80% (by mass of the suspension) shall be included in the total water content. The maximum ratio between water and cementitious materials plus mineral fillers is 0.50 (by mass).

    e. Chemical admixtures meeting ASTM C494 or C1017 may be used.

    f. Aggregate shall be non-metal aggregates meeting fine aggregate requirements described in ASTM C33. In addition, fine aggregate selected shall have 100% passing sieve size 4.75 mm (No. 4). The mixture must contain 60% (by mass of the whole mixture) aggregate as a minimum. See Table 1 for a summary of ASTM C33 fine aggregate requirements. The mix design needs to be reported in SSD conditions.

    g. The aggregate needs to be delivered at or below SSD condition at the moment of the competition. No water shall be added to correct for a moisture condition, as it is uncertain how much of the water will be absorbed by the aggregate. SSD condition may be verified on site through ASTM C 128. The mass of aggregate (min. 60%) will be considered in its totality on-site for the competition, regardless of its moisture condition.

    h. For every liquid chemical admixture, a solid content of 40% will be assumed. The remaining 60%, which is assumed to be water (by volume), will be counted as water content and will influence both w/cm and the total mixture mass (and thus the relative sand content).

        Table 1: ASTM C33 fine aggregate requirements

     

     

     

    3. Written Report

    Teams shall submit a unique written report meeting the requirements listed below for the judges to review and score before December 12, 2019. An electronic version of the report in standard PDF format (not in Microsoft Word or similar) shall be submitted as described below and detailed in Appendix A. The electronic report due date is indicated in Section 7. A hard-copy version shall be also submitted at the competition as described below for display during the first day of the competitions on December 25,2019. The hard copy shall be on standard letter size paper (or A4 format) and bound together. Teams failing to submit the hard-copy version of the report shall receive a zero in the report section of the Final Score equation given in Section 5. Failure to submit the electronic report prior to the competition will be considered as a withdrawal from the competition, despite the intention of the team to compete.

    The report must consist of the following sections: Cover Page, Abstract, Introduction, Methodology (Materials and Mixture Proportions, Procedures), Results, Discussion, Conclusions, and References. All reports shall be scored between zero and 100%, with 100% being the best. Table 2 shows the point allocation that the judges will use to score the report:

    4. Testing/Cost Evaluation

    a. Each team is to prepare two sets of raw materials (cementitious materials, filler [if applicable], aggregate(s), chemical admixture(s)). The two sets of raw materials shall be identical and provide 650 ± 100 mL of final mortar mixture. All materials, except water and admixtures, are to be pre-weighed, bagged individually, and brought to the competition. Admixtures may be measured at the competition site, but must be supplied by the team. All bags shall be clearly labeled with the 5-character Team ID mentioned in Appendix A.2.iii and the type of material. The competition organizer will prepare appropriate measures for water measurement on-site. The chemical admixtures can only be measured by means of a syringe (provided by the team) (by volume) on site. The judges will inspect both sets of raw materials and verify compliance with the rules, including the amount and gradation requirements. Both sets of identical raw materials shall comply with the rules (see Section 8). Note that in order to ensure all raw materials arrive on time, all teams are strongly encouraged to contact their traveling companies regarding regulations of baggage and carry-on allowance, particularly liquid—that is, chemical admixture(s)—prior to their travels.

    b. The judges will randomly select one set of the raw materials for mixing. c. Mixing

    i. If necessary, a judge will verify the water content of the sand by means of the procedure described in ASTM C-128. If the judges deem that the aggregate is above SSD condition (the sand does not slump), the team will be disqualified.

    ii. All bagged materials will be weighed by a judge prior to mixing. The entire quantity of each bag containing solid materials must be added to the mixer. In other words, teams are required to provide all solid materials, pre-weighed in separate bags for each material, and no adjustment to the quantity of (solid) materials can be made on-site. Teams should consider that the moisture content of the sand may vary during transportation and on-site, and should ensure that regardless of the moisture content, 60% of the mixture mass is composed of aggregates.

    iii. The teams have 5 minutes to prepare the water and admixture quantities on-site.

    Rules section 4.a will be strictly enforced concerning the measurement of chemical admixtures.

    iv. A standard 5 qt laboratory mixer provided by the competition organizer, is to be used for mixing. Each team will be responsible to mix their own mixture on-site. It is recommended to follow ASTM C305; however, a team can decide their own mixing procedure, based on the selected mixing procedure as described in the written report. The maximum mixing speed on the mixer is not allowed to be used. A maximum of 10 min is allowed for each team to have their mixtures prepared and handed to the judges. The 10 min period starts either when turning on the mixer or when adding the mixing water to the mixer bowl.

    v. Should the team determine that the workability of their mixture does not meet their expectation, the team will be allowed to adjust the quantity of 1 (one) chemical admixture, employed in the reported mortar mixture, relative to the mix design reported by the team. Multiple additions of the same chemical admixture are allowed, as long as the total mixing time does not exceed the maximum of 10 (ten) min as specified in section 4.c.iv. Each addition should be reported to the judge. Failure to report each addition, exceed the maximum of 10 min allowed mixture preparation time, the adjustment with multiple chemical admixtures (on site), or the use of a chemical admixture which is not incorporated in the reported mortar mix design will lead to disqualification of the team. It should be noted that when adding chemical admixture on-site, 60% of its volume will be counted towards w/cm and may also affect the relative sand content. Exceeding the maximum w/cm by the on-site addition of extra chemical admixture, even when the design w/cm in the report was below 0.50, will result in disqualification. As a consequence, designing the mixture at the maximum w/cm prescribed in the rules will not permit the inclusion of any “extra” liquid chemical admixture on-site. Upon completion of mixing, the bowl with the mixture shall be weighted. The mass of the bowl (determined before the competition) will be subtracted. The volume of the mortar will be derived from the mass based on the density or relative density (specific gravity) of the mixture, which will be taken from the submitted report. If the volume of the mixture is out of the allowable limits: between 550 and 750 mL, the team will be disqualified.

    vi. Upon the completion of mixing, the judges will collect the mixing bowl and pour mixtures into two standard 250 mL containers, with each container filled with 250

    ± 10 mL of mortar mixture. The latter container of mixture is to be used for the flowability test (see Section 4.d) and the first filled container of mixture is to be used for the stability testing (see Section 4.e).

    vii. Each team is then to deposit the surplus mixture into the designated cleanup area.

    The team is responsible for cleaning the mixing bowl, paddles, and any other

    tools used in mixing appropriately. An additional 10 min is allowed for cleanup time. Teams failing to properly cleanup will be disqualified from the competition.

    d. Flowability Testing

    i. Mixture from the second filled container as prepared in Section 4.c.vii will be used for flowability testing.

    ii. Within 3 min after the mixture is delivered to the judges, judges will pour the mixture into the aci mold through a funnel with an opening of approximately 12 mm. During the process of the mixture being poured into the funnel, the judge will be filling the funnel while holding his/her finger over the end of funnel until all materials from Section 4.d.i are poured into the funnel. The judge will then place the opening of the funnel right above the opening of letter “a” and release the mortar mixture into the mold flowing under the force of gravity alone. A

    detailed drawing of the mold can be found in Appendix B. Molds will be provided at the competition site. Students may use the drawing to fabricate their own mold for testing at their own school, although the competition molds may not behave exactly similar to school training molds. Time for the mixture to fill the mold— that is, from mixture poured into top of letter “a” to the time for mixture to come out from top of letter “i”—will be recorded. No vibration and/or consolidation

    will be permitted during the pouring process. A maximum of 3 min will be allowed for the mixture to flow through the mold.

    iii. If the mixture is not able to fully fill the mold, the degree of mixture filling the mold will be recorded. The degree of mixture filling the mold will be recorded when there is no obvious flow continuing. This will be no later than 3 min from the initial filling.

    iv. The judges will score the flowability test from each entry using the following scoring percentage (based on a total of 100%):

    a. Mold filling time – 40%

    b. Mold filling percentage – 60%

    Notes: “Mold filling time” category only applies to teams with mortar mixture completely filling the aci molds—that is, if the mortar does not completely fill up the mold, 0 points will be awarded in the category. The final score for the flowability testing is, F = 0.6 x Fp + 40 x (30 – Ft) / 30. Where Fp = filling percentage (in %) and Ft = filling time (in s). A filling time larger than 30 s will lead to zero score for the filling time part. No negative score for the filling time will be allocated. The scores are based on the performance of each mixture, not on the ranking of teams.

    For example:

    Team 1 fills the mold in 6 s. Total score = 0.6 x 100 (perfect filling) + 40 (30 – 6) / 30 = 60 + 32 = 92.

    Team 2 fills the mold in 24 s. Total score = 0.6 x 100 + 40 (30 – 24) / 30 =

    60 + 8 = 68.

    Team 3 fills the mold in 45 seconds. The total score = 60, as the filling is

    100%, but the time is larger than 30 s.

    Team 4 fills the mold to 75%. The total score = 0.6 x 75 + 0 = 45.

    e. Stability Testing

    i. Mixture from the first container as prepared in Section 4.c.vii will be used for stability testing.

    ii. Within 3 min after the mixture is delivered to the judges, judges will pour the mortar mixture into a 250 mL graduated cylinder. The cylinder will be filled for a minimum of 230 mL and a maximum of 250 mL. The exact volume (to the

    nearest 2 mL) will be determined by a judge on site. A photograph will also be taken.

    iii. After letting the cylinder rest for 30 min, a reading of the solid-liquid separation line in the cylinder, to the nearest 2 mL, will be made by a judge. A photograph will also be taken.

    iv. The teams will be scored over the ratio of the solid-liquid line after 30 min of rest, relative to the initial volume, called Rs, expressed in %. At least two other judges will determine both readings of 4.e.ii and 4.e.iii from the taken pictures. The average of at least three measurements will be used to calculate the stability score as: 4 x (Rs – 75). Stability scores cannot be negative. Rs values lower than 75% will lead to a zero score on the stability test. For example:

    vii. The teams should refer to the detailed cost scoring sheet found in Appendix C.

    5. Scoring

    Two competition categories are considered: the overall efficiency category and the economical design category:

    a. The overall efficiency score will be calculated as described below. The team that achieves a score with a value closest to 100 will receive the prize of first place. The teams with the next values in descending order will receive the prize of second and third place. In the case of a tie, the winner shall be the team with the better flowability testing score.

    Overall Efficiency Score = (0.50)(F) + (0.20)(S) + (0.25)(R) + (0.05)(C)

    where

    F is Overall score from flowability test

    S is Overall score from stability test

    R is Overall score from the written report section

    C is Overall score from the cost category

    b. The economical design category will NOT take place this year.

    c. Considerations: Competing teams should be aware of the consequences of some of the rules. Judgments on the compliance of the mix design and materials with the rules will be made twice: once before the competition by means of the report and once during the competition based on the batch weights of each material. The following should be kept in mind:

    • In the report, the mass of the sand should be expressed in SSD condition, and needs to fulfill the minimum mass requirement of 60%. However, on- site there is no possibility for the judges to determine the moisture content, apart from the distinction between above and below SSD. No water shall be added to compensate for absorption. The recorded mass of the sand on- site, regardless of its moisture condition, will be used to re-evaluate the

    mass of the sand relative to the mass of the mixture. If a team decides to design the mortar with a sand content exactly at 60% in SSD condition, this would induce a large risk, as the team needs to deliver the sand in SSD condition. Above SSD would mean disqualification and a sand content

    below SSD condition would lead to a slight (but non-negligible) reduction in the mass of the sand, which will no longer satisfy the “mass sand ≥ 60%

    mass mixture” rule.

    • As the water content in the admixtures is taken into consideration for w/cm, any adjustment on-site, especially an increase, will result in more water being added to the mortar. This extra water can push the w/cm ratio (even slightly) above 0.50, especially if the mortar is designed right at w/cm =

    0.50. Also the mass of the sand relative to the (recorded) mass of the mixture may be influenced.

    • These requirements will be verified on-site, and judges will be very strict in evaluating compliance with the rules. Teams should take these considerations into account when designing their mortar mixtures.

    6. Judging

    a. The judges will be appointed by the ACI Iran Chapter student competitions committee. Judges may be different for each testing category.

    b. The lead judge will make the final determination on compliance with the rules and penalties for rules violations under advisement from the other judges. Disqualified entries shall not be included in the scoring or considered for awards. See Section 8.

    c. The decision of the judges will be final, and appeals will not be considered.

    Suggestions for improvement may be submitted to the ACI Iran Chapter student competitions Committee.

    7. Registration and Material Submission

    a. Registration is required. Teams shshould send the registration form for their entry via email to convention@aciiranchapter.org . This form shall be submitted to ACI by December 6, 2019. It indicates the team’s intent to enter the competition. The Regestration form can be downloaded from the ACI Iran Chapter website at www.aciiranchapter.org.

    b. The electronic report, as described in Section 3, shall be submitted via e-mail at mortar@aciiranchapter.org no later than December 12, 2019.

    c. The hard copy of the report for each entry along with the bags of materials shall be submitted at the competition site on the first day December 25, 2019 in person at competition registration. Competition registration will open at 8:00 am.. Registered teams will be divided into groups for registration and competition scheduling. These group times will be posted at the competition area and sent to registered teams prior to the competition. Teams checking in past their check-in deadlines will not be accepted for entry into the competition.

    8. Compliance with ACI-Workability Competition rules

    ACI reserves the right to perform detailed examination and check entries for compliance with the competition rules. Due to the complexity of this task, the examination may be done after the competition. If the examination shows that a team did not follow the rules, the team, their

    advisor and all his/her teams will be disqualified. The ACI Iran Chapter competition committee will further document recommendations to sanction the team and its advisor and/or the school/university’s participation in future competitions. Failure to supply the required submittals or failure to meet the established deadlines may result in penalties, up to and including disqualification.
