The American Concrete Institute announces the winners of its 2018 Pervious Concrete Cylinder Student Competition. The competition took place at the recent Concrete Convention and Exposition in Las Vegas, NV, USA. The first, second, and third place in the Cylinder Performance, and Cementitious Efficiency categories each receive cash awards of $750, $500, and $250, respectively.
Teams were challenged to apply sustainability concepts and to use their knowledge of concrete mixture design by producing pervious concrete that balanced permeability and splitting tensile strength. Teams were additionally challenged to develop a mixture design that demonstrated cementitious efficiency; that is, maintaining the overall performance of the mixture with the lowest amount of cementitious material.
