We appreciate your interest in the Spring 2024 ACI Mortar & Workability Competition. This spreadsheet will guide you through a mixture proportion submittal.

The mixture proportioning in this competition is based on the absolute volume method. This means that all mortar constituents (including admixtures, if used) are proportioned by weight (kilograms) of a unit volume of the mixture (1 cubic meter). In other words, the total volume of all constituents must be 1 m³.

To complete your team's submission, you are required to fill out two portions of this sheet: (1) Team Information below, and (2) Mix Design on the second sheet of this workbook.

For the purposes of this competition, the reference density of water is 1 g/cm³ (=1000 kg/m³). The tons used in this competition for cost purposes are metric tons, i.e. 1 ton = 1,000 kg.

Please refer to the Official Competition Rules (Rules) for further details on the mixture requirements. Please do not submit a mixture that:

(1) does not yield correctly (i.e. the volume sum of all mixture constituents is not 1 m³), and
(2) does not meet the requirements as specified in the Rules.

The spreadsheet will automatically calculate batch weights to be used for on-site competition based on the specified volume of the batch. Please verify that the calculated batch weights correspond to your calculations prior to submitting the form.

Mixture proportions and cost calculation must also be submitted as part of your report; submitting this spreadsheet does not waive this requirement. Your written report's mixture proportions and cost calculations must match the values submitted in this spreadsheet.

Please note that you will not be allowed to make any changes after submitting the spreadsheet.

Should you have any questions, please do not hesitate to contact us at xxx@concrete.org.
