Performance of recycled aggregate in pervious concrete

Abstract

Pervious concrete can be noticed as a gap-graded concrete. This type of concrete treats a new way to control or manage of storm water. The pervious concrete is important to address bionomical issues and confirmable growth. In beside, demand for aggregate to producing concrete is still high while natural resources are reducing. In this connection at attempts has been made for utilization of recycled aggregate in the concrete mix, by replace the natural coarse aggregate in the ratio of 0, 25, 50, 75 and 100%. To obtain the behavior of pervious concrete compressive, split and bearing strength are evaluated. In the addition to those strengths, coefficient of permeability also found. In this experimental work total five mixes are taken to evaluate strengths. A regression model has developed to assess the split tensile strength and ANSYS software has been used to know the stress and strain variation for the cube specimens. From experimental work, it is noticed that, the pervious concrete with recycled aggregate is viable for pavement works.
