INVESTIGATION ON ALKALI ACTIVATED FLY ASH BASED GEOPOLYMER CONCRETE

Abstract

Cement industry plays major role for emission of greenhouse gasses. So, there is need for manufacturing of environmental friendly concrete. Geopolymer concrete helps in reduce global warming as well as fly ash disposal problem. This paper presents study the effect of types of curing, temperature, curing time and rest period. These parameters were studies like one variable parameter and other three are fixed parameter. One by one these parameter were finalize. The types of curing analyze with temperature optimization, rest period and curing time of geopolymer concrete. The type of curing like oven, accelerated, membrane, steam, wet and natural sun light (room temperature). The temperature differs like 600C, 900C, 1200C and 1500C. Once the temperature for type of curing is lock then proceed to curing time i.e. 6, 12, 18 and 24 hours. At the end temperature, type of curing and curing time finalize then optimize the rest period or testing age of concrete. The rest period differ like 1, 3, 7, 14, 21, 28, 56 days. In this study these variable are to be analyze with the help of compressive strength of geopolymer concrete.
