Abstract
Geopolymer concrete technology is a promising technology for the construction industry. Replacing the conventional resource consuming Portland cement with supplementary cementitious material can reduce the carbondioxide emission as well as energy consumption. It serves as an effective way of disposing industrial wastes that found difficult to be handled in past. Rice husk ash, an agricultural biomass which is rich in silica can be used as an effective source material. In the present study M30 grade GGBS and rice husk ash based geopolymer concrete is developed. Rice husk ash of varying percentage of 5 and 15% is considered to study its effect on mechanical and durability properties. 6 M sodium hydroxide is used. Ratio of sodium hydroxide to sodium silicate used is 1:2. Ambient curing of 28 days is done. The result is compared with OPC concrete specimen to evaluate the performance of geopolymer concrete.
