An Experimental Development on Pervious Concrete by Partial Replacement of Flyash, GGBS, Silica Fumes with cement by adding Glass Fiber

Abstract

Pervious Concrete for the pavements proves to be an effective and a long-term solution for the universal problem of abnormal decrease of ground water table. Pervious Concrete has a unique mix design and giving special properties to the concrete which makes the concrete porous, allowing water from precipitation and other sources to pass directly through , thereby reducing run off volume and increasing ground water table. In order to reduce the damage being caused to the environment by the use of cement , in pervious concrete , cement is replaced with pozzolanic materials such as flyash , GGBS , silica fume sand to increase strength and durability , glass fibers in stipulated ratio are added to the concrete mixture. In this study, the mix designs such as M30 and PC30 are considered. The fine aggregate is replaced with coarse aggregate by different ratios like 0% , 5% , 10% ,15%. by adding different pozzolanic materials like flyash, GGBS, silica fumes with glass fibers. To find the effectiveness of the use of pozzolancic and glass fibers, compressive strength and split tensile strength are conducted.
