EXPERIMENTAL INVESTIGATION ON MECHANICAL PROPERTIES OF CONCRETE BY PARTIAL REPLACEMENT OF CEMENT WITH FLYASH AND KADAPA STONE POWDER

Abstract

Concrete is the most important construction material for civil engineering. Concrete is one of the most durable
materials. The concrete of its Flexibility, Durability, Sustainability, and Economy have made it the world’s most widely used
building material. In the manufacturing of one ton of cement of lime stone, 80 Units of electric power apart from one ton of
CO2 at large into the atmosphere. Out of the total CO2 emission (from a variety of resource) worldwide, even industries
contribute about 7% of CO2 emissions. Annual cement manufacture rate of the world is increasing very much year by year.
But at present researchers are in interest of finding new materials by waste produced from industries which are harmful to
environment. Fly ash is a by-product of the combustion of pulverized coal in electric power generating plants. It is the most
widely used supplementary cementitious material in concrete. In Kadapa district, there are number of stone polishing
industries and huge quantities of fine powder from the process of polishing the stones to convert them into polishing stone
suitable for laying of flooring and other such works, is generated. The present paper deals partial replacement of cement
with fly ash and kadapa stone powder. In this experiment work 20%, 30%, 40% of fly ash and 5%,10%,15% of kadapa stone
powder were partially replaced with cement. The mechanical properties like compressive strength, Split Tensile Strength and
Flexural Strength of concrete were investigated with reference to conventional concrete
