Penetration and Strength Analysis of Pervious Concrete

Abstract Porous concrete is an amalgamation of coarse aggregate, Portland cement, and water, which permits rainfall water to permeate through the surface and into the ground before it runs off. Porous concrete encompasses little or no fine aggregates and adequate cementitious fixative to coat the coarse aggregate while keeping the voids interconnected. IRC 44-2017 states that range of permeability for pervious concrete should be from 0.135 cm/second to 1.22 cm/second and array of compressive strength should be 5MPa - 25MPa. In this experimental study, two properties of no fine concrete namely compressive strength and porousness at the curing age of 7th & 28rd days has been targeted. Compressive strength and Infiltration tests were conducted on the pervious concrete of grade M10 and M15 by keeping variation of fine aggregates of 0% - 5%. We observed that fines aggregate help to rise the compressive strength of porous concrete but decrease the permeability. Thus, by careful optimization of the mix, pervious concrete can be obtained for suitable use in low strength load.
