20% replacement of cement with Stone Dust and 50% replacement of fine aggregate with Crushed fine aggregate. Key Words: Stone Dust, Crushed fine aggregate, quarry dust, Flexural Strength, concrete. 1.INTRODUCTION Cement is the most active component of concrete usually has the greatest unit cost, its selection and proper use are
This quarry dust is replaced as 20%, 40%, 60% to the fine aggregate. In this study compressive strength and split tensile of concrete was evaluated to investigate the optimal use of quarry dust as fine aggregate in concrete. Concrete is a widely used construction material due to its strength and durability.
compressive strength than normal concrete and 50% crusher dust concrete. It can also be observed that replacement of crusher dust has shown more compressive strength than normal concrete and 50% crusher dust concrete as well as it is gradually increasing form initial day of curing to final day of curing i.e., up to 28 days of curing.
