A Study on Partial Replacement of Cement with Rice Husk Ash & Fine Aggregates with Ground Granulated Blast Furnace Slag

Partial replacement of cements and ?ne aggregates by industrial wastes are the current trend of preparing sustainable concrete since production of cement produce large amounts of carbon di-oxide and other greenhouse gasses that cause global warming. The present work explores the suitability of industrial waste Rice Husk Ash (RHA) and Ground Granulated Blast Furnace Slag (GGBS) as an alternative material for the cement and ?ne aggregate in the production of concrete. The Ordinary Portland Cement (OPC) has been replaced by 0-30% with RHA and 20%, 40%, 60% GGBS in place of ?ne aggregate. The objective of the paper is to study the partial replacement of cement with Rice Husk Ash & Fine Aggregates with GGBS of concrete. Experimental result shows that concrete mix consisting 40% GGBS with 10% RHA produce similar or even more compressive strength of normal concrete and all mixes at 28 days of curing age. However, considering all the properties of concrete, R10G40 gives robust performance than that of other mixes and it was recommended percentage for the concrete.
