Due to the enormous increase in the development of infrastructure in a very short span, there is an urge in the need of cement that is commonly used as a binder in the construction industry. This research work carries out the formation of self-compacted geopolymer concrete with the help of alkali activators that are used for curing under ambient curing. Durability, mechanical properties and microstructural analysis of ten different types of mixes of concrete with different combinations of fly ash, micro fly ash and slag were studied in detail. The formed mixes do not have any cement content and superplasticizers when tested are found to attain compressive strength of about 45 MPa at 28 days when compared to the normal concrete.
由于基础设施在极短的时间内飞速发展，因此对水泥的需求也在急剧增长，水泥通常被用作建筑行业的粘结剂。本研究工作借助碱激发剂形成自密实的地质聚合物混凝土，碱激发剂用于在环境养护下进行固化。详细研究了十种不同类型的混凝土混合物的耐久性、力学性能和微观结构分析，这些混合物的组合中分别含有不同比例的粉煤灰、微粉煤灰和矿渣。在测试过程中，所形成的混合物没有任何水泥含量，当与普通混凝土相比时，在 28 天时发现它们具有约 45 MPa 的抗压强度，并且具有超塑化剂。
