Experimental Investigations on Previous Concrete Produced by Blending Recycled Aggregates along with Low Density Aggregates

Abstract

Pervious concrete is a special type of concrete, which consists of cement, coarse aggregate, water with the minimal or no fine aggregate and admixtures if required. Due to high void ratio Pervious concrete allow storm water to infiltrate into the soil and overcome runoff problems. In this paper, the main aim is to develop a pervious concrete using recycled aggregates along with the low-density aggregates i.e., cinder for sustainable construction. Use of recycled aggregates along with cylinder aggregates helps to produce acceptable service concrete having both drainage and strength properties. The mix ratios of cinder and recycled aggregates in this paper is varied in the proportion of 50-50%, 75-25%, 25-75% and full replacements. The pervious concrete specimens were evaluated by determining the compressive strength, split tensile strength test at 7 & 28 days curing and permeability test after 28 days.  But it can be noted that with increase in strength, the permeability of pervious concrete will be reduced. Hence, the improvement of strength should not affect the permeability property because it is the property which serves its purpose.
