Analysis of Strength of Concrete with Partial Replacement of Cement with Fly Ash and Fine Aggregate with Blast Furnance Slag Sand

The utilization of waste materials from the industries has been continuously gaining emphasis in the construction work recently. The present work is to use Processed Granulated Blast Furnace Slag Sand and Fly ash as combined replacement for river sand and ordinary Portland cement respectively. M35 grade of concrete with W/C 0.4 will be adopted with two percentages of cement replacement by Fly Ash i.e, 30% and 40%, along with this the slag sand is varied from 0% to 100% in step of 20%. In first variation, 30% Fly Ash is replaced by cement and slag sand is varied as 0%, 20%, 40%, 60%, 80% and 100%. In second variation, 40% GGBS is replaced with cement and slag sand is varied as 0%, 20%, 40%, 60%, 80%, and 100%. For all mixes compressive strength, split tensile and flexural strength will be determined at different days of curing. The strength of cube specimens, cylinders and beams will be determined and compared with conventional concrete specimens. The beams are tested for flexure, under two point loading condition. Different parameters will be investigated in detail. In this paper literature is reviewed in detail to understand the experimental analysis.
