摘要：This research centers around the growth of the strength and permeability attributes of concrete by optimal substitution of cement with joint ratio of Fly ash (FA) and Rice husk ash (RHA) with Synthesis Egg shell powder (ESP). Two categories of ash such as fly ash, rice husk ash with four distinct contents of 5%, 10%, 20%, 30%, and 40% in terms of weight were performed for the substitution of cement and addition of a persistent 5% egg shell powder in every substitution. At first we have evaluated the physical and chemical attributes of fly ash, rice husk ash and egg shell powder. The restraints considered for analysis included compressive strength, splitting tensile power, flexure force, water permeability, sorptivity, total charge-passed acquired from swift chloride permeability test (RCPT) and tempo of chloride ion diffusion according to the diffusion coefficient. However, assessment results accomplished underscore the point that strength and permeability properties of concrete significantly jumping up to 30% of cement substitution by combined FA (15%), RHA (15%) with additive ESP (5%), and subsequently tends to drop down with every supplementary accumulation of substitution outside this level.
