This study involves the application of replacement material to cement which eliminates the carbon-dioxide emissions. Cement production industries alone give out 5 to 8 % of greenhouse gas into the atmosphere globally. Naturally, geopolymer concrete emits very low greenhouse gas compared to ordinary portland cement (OPC). Therefore, geopolymer concrete is greatly ecological and alternative material for OPC. This research has been intended to study the impact on workability and mechanical properties of fly ash based geopolymer concrete using ground granulated blast furnace slag (GGBFS) along with manufactured sand (M-Sand) under ambient curing condition. The work has been executed to explore compressive strength of G30 grade geopolymer concrete along with split tensile, flexural strength and its workability. The result shows that there has been increased strength and decreased workability with higher GGBFS & M-sand. Further, it shows the optimum percentage replacement of 20% of GGBFS & 50% of M-sand has been yielded G30 grade geopolymer concrete easily. Based on the investigation, better strength has been achieved by full replacement of natural sand with M-sand. Statistical analysis such as simple linear & multi variables regression has been carried out and formulas have been anticipated to find relationship between the mechanical properties of geopolymer concrete while increasing percentage of GGBFS.

GGBFS和M砂对粉煤灰基高分子聚合物混凝土的可加工性和强度性能的影响

这项研究涉及将替代材料应用于水泥，从而消除了二氧化碳的排放。仅水泥生产行业就向全球大气排放了5％至8％的温室气体。自然，与普通硅酸盐水泥（OPC）相比，地聚合物混凝土排放的温室气体非常少。因此，地质聚合物混凝土是OPC的极大生态替代材料。这项研究旨在研究在地面固化条件下，将磨碎的高炉矿渣（GGBFS）和人造砂（M-Sand）一起使用对粉煤灰基地聚合物的可操作性和机械性能的影响。已经进行了这项工作，以探索G30级地质聚合物混凝土的抗压强度，抗拉强度，抗弯强度及其可加工性。结果表明，较高的GGBFS和M型砂提高了强度，降低了可加工性。此外，它显示出可以轻松获得G30级地质聚合物混凝土的20％GGBFS和50％M砂的最佳替代百分比。根据调查，用M砂完全替代天然砂可获得更好的强度。已经进行了诸如简单线性和多变量回归之类的统计分析，并期望使用公式来查找增加GGBFS百分比的地聚合物混凝土力学性能之间的关系。通过用M砂完全替代天然砂，可以实现更好的强度。已经进行了诸如简单线性和多变量回归之类的统计分析，并期望使用公式来查找增加GGBFS百分比的地聚合物混凝土力学性能之间的关系。通过用M砂完全替代天然砂，可以实现更好的强度。已经进行了诸如简单线性和多变量回归之类的统计分析，并期望使用公式来查找增加GGBFS百分比的地聚合物混凝土力学性能之间的关系。
