ACI Iran Chapter ECO Concrete Competition
1. OBJECTIVES AND PRIZES
In order to follow the current orientation of the concrete industry, this student competition aims to promote the idea of environmental performance in concrete mix design as an important aspect of sustainability. Teams thus have the mission to develop an innovative concrete mixture, which will have the lowest possible environmental impacts while maintaining optimal mechanical and durability performances. To achieve this goal, teams are encouraged to seek out and use local resources of concrete materials such as supplementary cementitious materials (SCMs), alternative SCMs, fillers, recycled and alternative aggregates, and other environmentally friendly materials.
After designing their concrete mixture, teams are asked to perform a simplified life-cycle assessment (LCA) and present their results in a written report and a poster. The format of this report is inspired by an environmental product declaration document, which is favored by the industry to communicate the environmental footprint of products.
In addition to the report, teams shall prepare two concrete cylinders of their alternative-case and base-case scenarios and carry them to the competition place. The four total cylinders will be submitted early on December 25, 2019 morning of the convention and will be tested for compressive strength and resistivity at an offsite lab, and their results factored into the overall score. At the competition, teams will also have to present a poster of their innovative concrete to the audience and judges, with an emphasis on the environmental aspect considered in their mix design.
The use of recycled aggregates and/or alternative supplementary cementitious materials combined with the quality of the written report, environmental score from the simplified life-cycle assessment, and the results of the hardened tests will be the parameters in determining the winners.
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.

The aggregate(s) shall constitute a minimum of 50% of the total mass of concrete mixtures meeting aggregate requirements described in ASTM C33. This percentage shall be calculated based on a comparison of the total mass of all aggregates in surface saturated dry (SSD) condition, to the total mass of the concrete (based on yielded proportions). The contribution of coarse aggregates (aggregates with a minimum size of 5 mm) mass must be more than 30% of the total aggregates mass.
The concrete specimens shall be cured according to ASTM C192 prior to submitting. The specimens must also meet all the requirements for testing (as specified in Section 2.6.b), which includes providing two specimens for each mix design in a fully saturated state for resistivity and compressive strength testing.
2.5 Simplified Life Cycle Assessment
Each team must prepare a simplified LCA using the EcoConcrete Calculation Tool V2.01, following the specifications listed below. This simplified LCA calculates environmental impacts of the mixtures. For each process, five environmental impact categories, namely global warming, carcinogenic, ozone depletion, ecotoxicity, and fossil fuel depletion, are computed. The average reduction in the value of these five categories is considered to form the Single Score Ratio. More information of this approach is provided in the “EcoConcrete calculation tool instruction” document provided on the competition website at www.concrete.org if available at the time.
a. Goal and Scope
The objective of this competition is to design a concrete mix using an alternative material with low environmental impacts while preserving good mechanical properties AND good durability.
b. Functional Unit
The functional unit is the production of one cubic meter of concrete mixture complying with rules mentioned in sections 2.2 and 2.3.
c. System Boundaries
The system boundaries analyzed, in compliance with ready-mix concrete supply chain, including the extraction of the raw materials to production of one cubic meter of ready-mix concrete (refer to Figure 1). Each team shall comply their Simplified LCA with the following system boundaries for a cradle to gate:
Figure 1: Schematic representation of system boundaries
i. Extraction of raw materials and transportation to plant;
ii. Transportation of processed or raw materials from plant or site to the batching plant (your school location);
The following shall not be included in the simplified LCA:
iii. Production of concrete at batching plant (your school location);
iv. Manufacturing and maintenance;
v. Demolition and end-of-life.
d. Inventory (to be completed in the EcoConcrete Calculation Tool V2.01)
Each team shall consider electrical and/or thermal energy used to produce (transform) each material into concrete mixture ingredients. The appropriate energy mix of the region must be selected in the EcoConcrete Calculation Tool V2.01 to represent their local production;
i. Transport of each material should be considered. The batching plant shall be the location of your university lab.
Each team shall provide a travel map demonstrating the transportation path of each input material. Each transportation impact should be listed in the calculation table provided in the EcoConcrete Calculation Tool V2.01.
Each team must design two concrete mixtures using the corresponding worksheets in the EcoConcrete Calculation Tool V2.01: (1) Base-Case Scenario (BCS) and (2) an Alternative-Case Scenario (ACS). Both scenarios must respect criteria presented in sections 2.2 and 2.3.
2.5.1 Designing Base-Case Scenario and Alternative-Case Scenario
a. Designing Base-Case Scenario (BCS) concrete mixtures
i. BCS cementitious binder must be designed with 100% Portland or hydraulic cement specified in section 2.2.a.
b. Designing Alternative-Case Scenario (ACS) concrete mixtures
i. ACS must be designed with the same amount of total cementitious materials (binder) as the BCS mixture (in kg/m³). Use of alternative materials is allowed.
ii. ACS must be designed with the same amount of total fine and coarse aggregates as the BCS mixture (in kg/m³). Use of alternative materials is allowed.
NOTE: All the inputs in the tool, such as materials, transportation distances, and the processing energy, must be based on reality and shall be explicitly presented in the report and poster presentation. In addition, all the identical materials in ACS and BCS (e.g. portland cement and virgin aggregates) must be supplied from the same source or plant.
After computing the environmental single score (SS) of each scenario (by the EcoConcrete Calculation Tool V2.01), a ratio is calculated, as presented in Equation 1, to highlight the relative environmental improvements from the base case to the alternative mix. A minimum 15% improvement in the environmental impact score is required for this competition.
SSACS = Single score of Alternative-Case Scenario
SSBCA = Single score of Base-Case Scenario
SSRatio = Single score ratio
Such scenarios will allow comparing relative environmental improvement of each team and avoiding geographical distortion.
2.5.2 Calculating environmental impacts with the EcoConcrete Calculation Tool V2.01
The EcoConcrete Calculation Tool V2.01 provides a simple way for students to calculate and compare the environmental impacts of the concrete mixtures. The Instructions for this tool are provided in the “EcoConcrete calculation tool instruction” document provided on the competition website at if available at the time.
2.6 Resistivity Testing and Requirements
The durability of the concrete mixtures will be determined through conducting electrical resistivity tests on two concrete cylinders for each mix design during the competition. Electrical bulk resistivity demonstrates a good agreement with certain concrete transport properties, such as permeability and diffusivity. This test will determine the electrical bulk resistivity of the specimens and will be conducted by Giatec Scientific RCON equipment, Proceq or equivalent. An alternating electrical current of 1 kHz will be applied to the concrete cylinders. The voltage and current will be determined to calculate the resistivity. Overall resistance will be used to generate a durability factor.
a. Specimen preparation
i. Two standard 100×200 mm (4×8 in.) cylindrical specimens for each mix design shall be prepared and cured for a minimum of 14 days according to ASTM C192.
ii. The specimens of each mix design shall be cast from the same concrete batch.
iii. Each specimen shall be labeled on the side by a permanent marker with the same four-letter designation stated in the report, along with a “1” and “2” to differentiate between the specimens. Marking is not permitted on the ends of the specimens.
b. Specimen submission and testing
i. Two specimens of each case shall be submitted in an SSD condition. Fully saturated specimens shall be wrapped in a plastic wrap to prevent drying of samples and submitted to the judges for testing between 8:00 a.m. and 8:30 a.m. at the competition area. If the examination shows that the specimens are not in SSD condition, the team will be disqualified.
ii. Judges will transport the specimens to an offsite laboratory to conduct the required testing.
iii. Judges will measure the diameter and height of the specimens.
iv. Judges will place the specimens into water baths for a period of approximately 4 hours. All specimens will be submitted to the same preparation treatment prior to testing; as such, the order of testing will most likely be in the order of specimen submission.
v. The specimens will be removed from the water and tamped surface dry by the judges. Judges will place the specimens into a device for measurement of electrical bulk resistivity.
vi. The voltage drop and current will be recorded by the judges.
c. Calculation of resistivity
i. Electrical bulk resistivity will be determined by the recorded current, voltage drop, and geometry of the cylinders.
ii. The following formula will be used to compute the bulk resistivity ρ (kΩ.cm):
R = Resistance of the concrete (kΩ);
A = Cross-sectional area of the cylinder (cm);
L = height of the cylinder specimen (cm).
Teams will be ranked on the relative improvement in bulk resistivity of their specimen when comparing ACS to BCS. The team with the higher relative improvement in bulk resistivity will obtain the highest rank and a score of 100. Negative improvement will result in a score of zero in this category. The remaining teams will be awarded scores of an evenly graduated decrease according to the total number of teams competing.
2.7 Compressive Strength Testing and Requirements
Concrete compressive strength tests will be performed on the two concrete cylinders of each case, which were carried by teams to the competition place with the same dimensions noted above (100×200 mm [4×8 in.]). Note that while a curing of at least 14 days is specified in Rules item 2.6 a., SCMs typically require 28 to 56 days to develop their compressive strength.
a. Calculation of compressive strength
i. Compressive strength shall be determined by the ultimate load and geometry of the cylinders
ii. The following formula shall be used to compute the compressive strength in MPa
P = Resistance of concrete (N)
A = Cross-sectional area of the cylinder (mm2)
Teams will be ranked on the relative improvement in compressive strength of their specimens, showing that how much increase in compressive strength was observed when using the ACS compared to BCS. Negative improvement will result in a score of zero in this category. The team with the largest improvement in compressive strength will obtain the first rank and a score of 100. Other teams will be awarded scores of an evenly graduated decrease according to the total number of teams (20 max).
2.8 Written Report
