Abstract
Geopolymer Concrete is the concrete made without using any quantity of cement. Instead the waste material from the thermal power station called fly ash is used as the binding material. This fly ash reacts with alkaline solution like sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) and forms a gel which binds the fine and coarse aggregates. Similarly another artificial material called manufactured sand (M-Sand) is also used as the fine aggregate against the normal river sand. The durability of Geopolymer Concrete with M-sand was studied by casting cubes of size 100 x 100 x 100 mm. The cube specimens were immersed in acid, alkaline, sulphate and chloride solutions respectively. The specimens were studied at the end of 3, 7, 14, 21, 28 and 56 days. The durability of Geopolymer Concrete with manufactured sand (GPCM) was better than the normal portland cement concrete.
