Properties of Geopolymer Concrete Produced by Silica Fume and Ground-Granulated Blast-Furnace Slag

Ahmed Mohmed Ahmed Blash, Dr. T.V. S. Vara Lakshmi

Abstract: In the construction industry, the main production of Portland cement causes the emission of air pollutants which results in environmental pollution. Geopolymer Concrete (GPCs) is a one type class of concrete based on an inorganic alumino- silicate binder system compared to the hydrated calcium silicate binder system of concrete. It possesses the advantages of rapid strength gain, elimination of water curing, good mechanical and durability properties and is eco-friendly and sustainable alternative to Ordinary Portland Cement (OPC) based concrete. This paper presents, to investigate the compressive strength of the Geopolymer concrete produced by replacement of Ground-granulated blast-furnace slag (GGBS) with SF (Silica fume) by 0 %, 20 %, 40 %, 60 %, 80 % and 100 %, and its studies carried out in varying molarity. The alkaline liquids were used in this study for the geopolymerization are sodium hydroxide (NaOH) and sodium silicate (Soi2). The geopolymer concrete specimens were tested for their compressive strength at the ages of 7, 14 and 28 days under two types of curing (water curing and room curing). Experimental investigations have been carried out on workability, the various mechanical properties of GPCs.
