Heat Optimization in Internal Curing Process of Geopolymer Mortar by Using Steel Dust

Endothermic is one of the fundamental characterics in geopolymer that involves external source of heat to activate the polymerization process to form strong hardened geopolymer. However, high temperature during curing process may lead to the drying shrinkage to the specimen and affecting the mechani...
