Jun 23, 2017 The softening and melting temperatures of slag were adjusted by changing the slag basicity and FeO content. A proper amount of Fe 2 O 3 or SiO 2 addition increased the crushing strength of DRI due to the softening of slag. Excessive Fe 2 O 3 or SiO 2 resulted in the melting of slag, which decreases crushing strength.Cement is replaced with Ground Granulated Blast Furnace Slag (GGBS), to produce a cost effective concrete and to gain effective compressive strength.

Tensile strength of the concrete by various replacement of Flyash and GGBS. The test results shows that strength increasing with the increase of flyash and GGBS up to optimum value beyond which strength value start decreasing with further addition of flyash and GGBS. Key words Fly ash, GGBS, Environment .problem,.This paper presents the effect of slag addition on strength development and workability of fly ash slag based geopolymer (FASLG) concrete cured at normal temperature. Class C fly ash with high ferrite (Fe) content was used as the primary material. The proportions of fly ash (FA) to slag (SL) are 1 FA 0 SL, 0.9 FA 0.1 SL, 0.7 FA 0.3 SL, and 0.5 FA 0.5 SL.
