ABSTRACT
ABSTRACT: Cement is the main constituent present in the production of concrete. The production of Ordinary Portland Cement (OPC) leads to huge emission of green house gases such as CO2. Fly ash based geopolymer binders are an innovative alternative to OPC which can provide high strength. Much research has been conducted on the properties of fly ash based geopolymer concrete hardened by heat curing, which is considered as a limitation for cast in situ applications of geopolymers. The aim of this study is to generate geopolymers cured without elevated heat. For this Ground Granulated Blast Furnace Slag (GGBFS) is also used as a binder along with fly ash in different percentages. The result obtained revealed that the addition of GGBFS in fly ash based geopolymer concrete enhanced its mechanical properties in an ambient curing condition.
