This book reports the results from the investigation on the behaviour of reinforced geopolymer concrete due to cyclic flexural load. Tests were also performed to investigate the behaviour of plain geopolymer concrete due to static compressive, tensile and flexural load. For the comparison of the results, similar type of tests were performed on some other types of concrete such Portland cement concrete, polymer Portland cement concrete, latex modified concrete and latex modified geopolymer concrete. Further, feasibility of geopolymer as rehabilitation material was investigated. Controlled specimen was tested under static and dynamic loads. The damaged specimens were then rehabilitated with geopolymer paste and geopolymer mortar and test again under tests similar to that of the controlled specimen.
