Mix Proportions. The mix design was divided into two parts. Part I was designed to
investigate the effects of aggregate size and type on the void ratio and strength of pervious
concrete, and Part II was to investigate the effects of sand, latex, fiber and admixtures (AEA and
HRWR) on PCPC properties. All concrete mix proportions used are summarized in Table 2. The
slump of the mixtures was between 0 in. to ½ in. (0 cm and 1.27 cm ).
