Strength Characteristics of Concrete Using Eco-Friendly Materials

Utilization of industrial waste products in concrete is gaining importance all around the world. Replacement with supplementary materials will address two problems by reduce Greenhouse gases and cost effective rice husk is the outermost layer of paddy it contains 86.94 % of SiO2 and Hypo sludge is such an industrial waste produced in plenty by paper mills. Therefore, In this paper, the effect of rice husk ash and Hypo sludge on properties of Ordinary Portland Cement (OPC) Concrete of M25 grade are investigated with silica fume as powder along with cement. The test was carried out to evaluate the mechanical properties like compressive strength of 7 and 28 days
