Home > Students > Student Competitions > Mortar Workability Competition
While current ACI competitions focus mainly on strength or hardened concrete performance, this competition will focus on workability and rheological properties of concrete. 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.
Flowablity, mixture stability, and quality of written report will be used to determine the winner of the competition. First-second-and third-place entries will each be awarded a certificate of recognition, will be recognized in Concrete International magazine if space allows, and will be recognized on ACI's website. In addition, the first-place team will receive a $750 award, the second-place team will receive $500, and the third-place team will receive $250. Winners will not be announced and prizes will not be awarded until the student lunch on Monday following the competition.
