A REVIEW ON PERFORMANCE OF PERVIOUS CONCRETE USING WASTE MATERIALS

Abstract

Pervious concrete is one of the most promising sustainable material nowadays. Pervious concrete is the mixture of cement, smaller size coarse aggregate, water and admixture. As cement industry is one of the most polluted industry, so for reducing the pollution and cost of concrete cement may be fully or partially replaced by waste materials like fly ash, rice husk ash, waste rubber tire, furnace slag, silica fume, solid waste etc. This paper illustrates the performance of pervious concrete with these sustainable materials replacing or partially replacing cement & aggregate. It is observed from the study that compressive strength of pervious concrete is increasing by introducing fly ash, furnace slag, and rice husk ash, silica fume, and solid waste (glass powder, ceramic waste, bottom ash). Whereas compressive strength is decreasing by addition of rubberized materials. Permeability is increasing with furnace slag, ceramic waste but glass powder, silica fume has no effect on permeability. Though rubberized materials decreases the tensile strength and compressive strength of pervious concrete, it increases the abrasion resistance & freezing–thawing resistance. Partial addition of rice husk ash, furnace slag, silica fume, glass powder also enhance tensile strength of pervious concrete. All the above mentioned materials are environment friendly but solid waste, furnace slag and silica fume has the highest contribution to the strength and permeability of pervious concrete.
