Abstract:

Geopolymer concrete is the developing alternative construction material by replacement of cement concrete, due to the environmental pollution cement is replaces by fly ash. Fly ash is the byproduct of thermal power plant industry and also it reduce the requirement of water, this paper study of geopolymer concrete in different environmental condition and implementation of daylight curing on geopolymer concrete. In practical, heat curing is not suitable during construction and is uneconomical. To overcome these difficulties, we prefer the daylight curing. The results compared cement concrete and geopolymer concrete under daylight curing. Mix proportion of cement concrete is under the guidelines of IS 10262-1982 using M25 grade concrete mix ratio cement: fine aggregate: coarse aggregate (1:1:2.70) and water cement ratio of 0.40. Geopolymer concrete mix proportion under “Modified guidelines of geopolymer concrete” using M25 grade and 12M mix ratio fly ash: fine aggregate: coarse aggregate (1:1.54:3.43) and alkaline solution fly ash ratio of 0.55. Concrete cubes of size 150X150X150mm were prepared and cured under different environmental condition. The compressive strength was founded out at 3, 7,14,21,28 days. From the results, the geopolymer concrete attains the compressive strength without hydro-curing. The M25 grade geopolymer concrete attains its target strength within 14 days of daylight curing.
