EXPERIMENTAL INVESTIGATION OF FIBRE REINFORCED BASED GEO-POLYMER CONCRETE

Fly ash based Geopolymer is considered as the third generation cement after lime and Portland cement. Geopolymer cements are acid resistant cementitious materials with zeolite properties, developed for the long term containment of hazardous and toxic wastes. The term geopolymer is generally used to describe an amorphous alkali aluminosilicate which was also commonly used for inorganic polymer, alkali- activated cements, geocements, alkalibonded ceramics, hydro ceramics etc. This research is carried to investigate the fresh, hardened, durability and structural behaviour of Fibre Reinforced Geopolymer (FRGP) concrete members. The casting and testing of FRGP concrete specimens were done according to the specifications followed for ordinary Portland cement mortar and concrete. The test specimens were heat-cured in an oven/heat curing chamber. The tests were carried out for the fresh concrete initially. The slump value and percentage of flow for fresh geopolymer concrete with and without polypropylene fibre were tested in accordance with ASTM-C143 and ASTM C1362-09 respectively.
