Abstract

The deterioration rate of plain GEOPOLYMER CONCRETE specimens when exposed to aggressive environment was low and the specimens were stable when compared to plain ordinary Portland cement concrete. Attention was paid upon the durability and flexural behaviour of reinforced GEOPOLYMER CONCRETE beams, manufactured using low calcium class F Indian FLY ASH, exposed to 10% concentration of sulfuric ACID ATTACK and CHLORIDE ATTACK for a period of 180 days.100mm100mm cross-section and 500mm long beams with 1% tensile reinforcement were cast. Concentration of sodium hydroxide was taken as 8M for a cube compressive strength of 30N/mm2. Test results showed very little surface erosion, 3.26% and 1% weight loss, 10.64% and 4.47% decrease in ultimate moment for specimens exposed to chloride and ACID ATTACKs, respectively. This has revealed better performance of reinforced GEOPOLYMER CONCRETE beams subjected to aggressive situation and is in line with earlier studies on plain GEOPOLYMER CONCRETEs. The erosion of surface of specimens had not led to corrosion of steel bars which underlines the GEOPOLYMER CONCRETEas an impermeable one. X-ray diffraction (XRD), EDAX and scanning electron microscopy (SEM) analyseswere done to compare results of reinforced GEOPOLYMER CONCRETE beams, before and after immersion in aggressive liquids.
