Influence of GGBS and Marble Dust on Mechanical Properties of Concrete

Abstract

Concrete is a extensively used material in construction. Due to high tech upgrading, the concrete have been matured to augment the equity of concrete. Now a day’s various studies have been conducted to make concrete with waste materials with the intension of reducing cost and demand of materials. This paper investigates the mechanical goods of concrete using Ground Granulated Blast furnace Slag (GGBS) and Marble Dust (MD) as a limited replacement of cement and fine aggregate respectively. Based on previous literature survey, 40% of GGBS and 10, 20 and 30% of MD are taken for the present study. The present research work is aimed at studying the mechanical properties of M20 grade concrete using GGBS and MD. Compressive strength and Split tensile strength were carried out for 7, 28 and 56 days and insignificant increases in the strength were observed for concrete specimens admixed with GGBS and MD when compared with conventional concrete.
