Abstract:

Not only is cement production very energy intensive, it also consumes a significant amount of natural resources. On the other hand, a large volume of volatile flyash is already creating around the world, most flyash are not effectively used, and much of it is deposited in landfills both issues are addressed in this paper. This study gives the resultants of an experimenting research on the mechanical properties of geopolymer compounds contain 70% flyash, 30% GGBFS, alkali fluids & steel fibers. The review analyzes effects of steel fibers on mechanical properties tests of FRGPC. The blends were prepared with an alkali solution to binder ratio of 0.4 with 30% flyash supplanted by GGBFS on a massive basis. Steel fibers were added to blend in the volume fractions of 0.5%, 0.75%, 1%, 1.25% and 1.5% by volume of cementitious material. The results of the mechanical tests obtained after 7 and 28 days of environmental curing indicate that included incorporation of fiber in GPC there is only a light increase in the compressive strength. In contrast, SplitTensile strength and flexure strength increase significantly and the water penetration experiment also shows that the FRGPC specimen is durable. The two limitations of GPC, such as the retard in setting time & the need for temperature hardening to increase strength were also eliminated by replacing 30% of fly ash per GGBFS in the GPC mixture.
