The American Concrete Institute has announced the winners of its 2011 Student Pervious Concrete Cylinder Competition. This competition is also sponsored by the Center for Maximum Potential Building Systems and the U.S. Green Building Council.
In this competition, teams are challenged to apply sustainability concepts and use their knowledge of concrete mix design to produce pervious concrete that balances permeability and splitting tensile strength (STS).
Teams are additionally challenged to develop a mix design that develops the highest load-to-cost ratio. A report that documents the team’s cylinder production process and preliminary results is scored.
Here are the winners:
