Experiment on mechanical properties of pervious concrete

Abstract

Pervious Concrete which is also called as No-amercement Concrete is a combination of cement, water and a particular size of coarse aggregate combines to form a porous structural material. The main application of pervious concrete in pavements is for storm water control which occurs mostly in urban areas where scarcity of land is high. Permeable Pavement allows surface runoff through it and hence stops the overflow which improves ground water recharge. In this paper investigation on compressive strength, flexural strength, water permeability, density and void ratio has carried at 0.33% water cement ratio(W/C) for cement aggregate ratio (C/A)0.25 to three set of coarse aggregate(CA)sizes without fine aggregate. Summarizing that 12.5 mm (passing) to 10 mm (retained) size of aggregates has shown good results than remaining sizes for compressive strength, permeability, density and void content.
