Durability of Geopolymer Lightweight Concrete using Industrial By-products Against Acid and Sulphate Attack
Authors(4) :-Pradeep H R, Raghavendra D, Shashishankar A, B R Niranjan The study presents the durability of the geopolymer lightweight (GPLW) concrete when exposed individually to 10% Sulfuric acid, 5% Sodium Sulphate solution and 5% Magnesium Sulphate solutions up to 90 days period. Class-C flyash and GGBFS were used as binder materials. Processed Slag sand was used as replacement to fine aggregates and sintered flyash aggregates as replacement to coarse aggregates. The GPLWC specimen were immersed in acid and Sulphate solutions after air curing for 90 days. The strength results of both OPC and GPLW concrete were compared. The compressive strength attained by GPLWC after 90 days was about 27Mpa to 43Mpa and after 180 days was about 30Mpa to 45Mpa. The corresponding compressive strengths in OPC concrete was 26Mpa and 28Mpa respectively. After 60 days and 90 days of exposure to sulphate solutions, the compressive strength decrease was in the range of -10% to 33% and -4% to 38% respectively for GPLWC and about 9% and 16% respectively for OPC concrete. Over the same period of exposure to 10% H2SO4 solution, the compressive strength had decreased and was about 13% to 44% and 14% to 48% respectively for GPLWC and about 10% and 20% respectively for OPC concrete. It is observed that, the selection of binder material is very important, as it adversely effects the strength of concrete to a greater extent.
