The recent technology of geopolymer concrete is a substitute material for ordinary portland cement concrete which is produced from the polycondensation reaction of aluminosilicate materials with alkaline activator solutions. The cost of river sand is high since the demand for the same is also high. Manufactured sand is used as a replacement material for river sand in geopolymer concrete. This paper mainly focuses to find the properties of fly ash (FA) – based geopolymer concrete under ambient cured temperature like compressive strength, stress strain behaviour, modulus of elasticity, Poission’s ratio and impact resistance. The result of geopolymer concrete is compared with ordinary portland cement concrete. The elasticity modulus and Poission’s ratio of geopolymer concrete are lower than conventional concrete. The Stress-strain behaviour of geopolymer concrete is similar to conventional concrete. The impact resistance of geopolymer concrete is very good when compared with conventional concrete.

粉煤灰-地聚合物和硅酸盐水泥混凝土的压缩，冲击及应力应变预测的试验研究

地质聚合物混凝土的最新技术是普通硅酸盐水泥混凝土的替代材料，它是由铝硅酸盐材料与碱性活化剂溶液的缩聚反应制得的。河砂的成本很高，因为对河砂的需求也很高。用人造沙替代地质聚合物混凝土中的河砂。本文主要着眼于在环境固化温度下找到粉煤灰（FA）基地聚合物混凝土的性能，例如抗压强度，应力应变行为，弹性模量，泊松比和抗冲击性。将地聚合物混凝土的结果与普通硅酸盐水泥混凝土进行了比较。地聚合物的弹性模量和泊松比低于常规混凝土。地质聚合物混凝土的应力应变行为与常规混凝土相似。与常规混凝土相比，地聚合物的抗冲击性非常好。
