Performance of concrete by partial replacement of cement by silica fume and fine aggregate by ground Granulated blast furnace slag

Abstract

The Average of River sand for construction has various undesirable and ecological consequences. As a solution for this industrial waste such as Ground Granulated Blast Furnace Slag (GGBS) can be used to replace partially by sand and cement by Silica fume. This research aims to investigate possibility of replacing GGBS as a sand substitute in concrete. In this investigation, natural sand was replaced by GGBS in various percentage (10%, 20%, 30%, 40% and 50%), with water cement ratio of 0.4 and cement was partially replaced by 15% Silica Fume. Material Tests were done for fine aggregate and GGBS sample. Different mix proportions for different percentage replacement of fine aggregate was obtain for M30 grade of concrete as per IS 10262:1982. The Compressive strength test, split Tensile strength test, Flexural strength test and Non-destructive Test (NDT) were done for concrete with various % of GGBS and constant % of Silica Fume in concrete.
