This test gives the result of laterally improvement of strength properties of mortar by the replacement of fly ash in cement in different Proportion Among six fly ash mortar (10, 20, 30, 40, 50, 60) the of mortar provides 14% compressive and 8% high tensile compared with ordinary Portland cement. Cement (PPC) than site mixing of fly ash with OPC under normal Indian construction site conditions. • Fly ash is effective in reducing water absorption capacity. Fly Ash . Fly ash affects the plastic properties of concrete by improving workability, reducing water demand, controlling bleeding, and lowering the heat of hydration. Importantly, the cementitious mixture includes greater than 50% of fly ash by weight, or alternatively greater than 75% by weight of fly ash, or still further alternatively greater than 90% or 95% by weight of fly ash. The global fly ash cement market size is expected to register a significant CAGR during the forecast period 2020 to 2027. Since the test is performed with mortar, the results may not provide a direct correlation of how the fly ash or natural pozzolan will contribute to strength in concrete.
