Experimental Study on Partial Replacement of Cement by Fly Ash, Silica Fume and Sand with Quarry Dust

Concrete is the most widely used construction material due to its good compressive strength and durability. Conventional concrete need water curing for a minimum of 28 days to achieve its target strength. The aim of the investigation is to evaluate the use Fly ash and silica fume in replacement of cement. Concrete of M30 grade were cast by replacing fine aggregate with 50 % quarry dust and by varying quantity of fly ash and silica fume by 5 %, 10 %, 15 %, 20 %, 25 %. In this study, compressive strength, split tensile strength concrete with optimum. Compression strength of concrete is tested on cubes at different replacements of fly ash and silica fume for 28days increased. Split tensile strength of concrete is tested on cylinders at different replacements of fly ash and silica fume for 28 days increased.
