These days, ecologically inviting building is getting to be a pivotal issue in development industry. The course towards economical concrete includes minimizing the natural affect of concrete generation and as well as diminishing the worldwide CO2 emanations. Universally, the concrete industry expends expansive amounts of characteristic assets, which are getting to be deficiently to meet the expanding requests. At the same time, expansive number of ancient buildings and other structures have come to the conclusion of their benefit life and are being pulverized, coming about in era of pulverized concrete. A few of this concrete squander is utilized as backfill fabric and much being sent to landfills. Reusing concrete by utilizing it as substitution to unused total in concrete may diminish concrete squander and preserve characteristic assets of total. Within the final two decades, assortments of reusing strategies for development and devastation squanders have been investigated and are in welldeveloped stages. Fly ash is known to be a good pozzolanic material and has been used to increase the ultimate compressive strength and workability of fresh concrete. The approach adopted here includes a 30 substitution of natural aggregates by recycled concrete aggregates as well as the use of (0,15,20,30) by mass of fly ash as a partial substitute of Portland cement. This paper discusses the strength characteristics of natural and recycled aggregate concrete using fly ash. The most important benefit is reduced permeability to water and aggressive chemicals. This increases strength and reduces permeability
