Strength Properties of Concrete with Rice Husk Ash, Slag Sand and Marble Waste Aggregate

Abstract

The growth in the next leg of industrialization and urbanization infrastructure is the biggest catalyst of India’s growth. As we know concrete plays a vital role in the construction industry, due to demand and depletion of natural resources alternatives are searched and adopted to make it feasible. Agro wastes and Industrial wastes are good options to adopt as alternatives as they cause harmful effects to the environment. In the present study, one of the Agro wastes, Rice Husk Ash due to its pozzolanicbehaviouris used as a partial replacement to cement, the replacement varies from 0% to 40%. Industrial waste and substitute to river sand, Steel Slag sand is used as a replacement to fine aggregate. Marble Waste Aggregate is obtained from the demolished construction site and crushed to the required size is used as coarse aggregate. Concrete mixes of M30 grade are prepared. Concrete specimens are cast and tested after curing of 7&28 days.Average Compressive strength, Split tensile strength and Flexural Strength are determined. In gist, this paper represents the strength properties of concrete with partial replacement of cement with rice husk ash and total replacement of conventionalaggregates with Marble waste aggregate and Steel slag as fine aggregate.
