Abstract
The deterioration rate of geopolymer concrete specimens when exposed to aggressive environment was low and the specimens were stable when compared to ordinary Portland cement concrete. Attention was paid upon the durability and flexural behaviour of glass fiber reinforced geopolymer concrete specimens, manufactured using low calcium class F fly ash, exposed to 10% concentration of sulfuric acid attack and chloride attack for a period of 3,7,15 & 30 days. 110mm x 100mm cross-section and 500mm long beams with 1% tensile reinforcement were cast. For Rapid Chloride Penetration Test (RCPT), 100mm dia and 50mm discs were cast. For water absorption test, 100mm x 100mm x 100mm cubes were cast. Glass fibers were added to the concrete mix as 0.01%, 0.02%, 0.03% and 0.4% to the volume of concrete.
