Abstract

This paper investigates the effect of replacement in Vertical Shaft Impactor (VSI) aggregates with Natural coarse aggregates on pervious concrete properties. Pervious concrete is a special type concrete prepared without use of fine sand. Pervious concrete is produced with different size of coarse aggregates. For the present investigation comparison has been made between VSI aggregates and Natural aggregates used in pervious concrete. The physical properties of Natural aggregate and VSI aggregate are compared. For the pervious concrete mix design, cement content, 375 3 -10 kg/m is used with 4.75 mm size of coarse aggregate. Three w/c ratios are used, such as 0.4, 0.425, and 0.45. The main properties were studied, such as void ratio, compressive strength permeability, and density. Comparison of results in Natural aggregate and VSI aggregate for making pervious concrete are included in this paper. Test results reveal considerable enhancement in the compressive strength of pervious concrete and other properties are found in similar range. VSI aggregate is a special type of aggregate having rounded edges. It has been found that VSI aggregates is more suitable to use in pervious concrete as compared to Natural coarse aggregates.
