    Abstract

    The effect of curing conditions, specimen type, and the use of super absorbent polymers on the Compressive Strength and Abrasion of Portland Cement Pervious Concrete was evaluated. Five different mixtures, using different water/cement ratios, and the addition of polypromancic based acid and polyacrylate based super absorbent polymers were tested. Half of the specimens were cured in a temperature-controlled room at higher temperature and lower humidity to simulate field conditions. Specimens that were cured in these harsher conditions showed reduced compressive strength in the range of 34% to 35% for cast cylinders, and 27% to 67% for cores when compared to specimens cured under ideal conditions in the lab. These samples also had 3.14 to 3.2 times the abrasion damage compared to laboratory cured samples of similar porosities.
