ABSTRACT:
Concrete is the material which is abundantly used in the construction industry and the production of cement is one among the reason for global warming due to release of carbon dioxide, to minimize its effect on nature we must use industrial by-product as an alternative material. Among industrial by-product, usage of fly ash is more. The geopolymer mortar made by the using fly-ash set slowly in ambient temperature and needs heat curing. To overcome this limitation, Ground Granulated Blast Furnace Slag (GGBS) powder is used as a cementious material which shows considerable gain in strength. In this paper, we investigated the properties of geopolymeric binder prepared using the Ground “Granulated Blast Furnace Slag” (GGBS) and coal ash without using conventional cement. The individual properties of the GM for 1:3 ratio, such as compressive strength test was determined as per relevant Indian standards. Cubes of size (70.6 x 70.6 x 70.6) mm were casted and cured in ambient condition for molarity 8M with different ratios and different temperatures. After the experiments, compressive strength is increased for increasing number of days of curing. Also, compressive strength decreased for increasing Na2SiO3/NaOH ratios and increasing oven curing temperatures.
