2019-7-1  Abstract: - Use of recycled coarse aggregate in concrete can be useful for environmental protection and economical terms. Recycled aggregates are the materials for the future. Same as fly ash is also a byproduct from various industries.This project presents the result of mix design developed for high strength concrete by adding the different kinds of unwanted material which is not be used and also the demolished concrete. In this research work the locally available constituents of concrete were selected for the purpose of determining their relative quantities and proportions for best result. In general, the RCA (Recycled Coarse Aggregate) has high water absorption due to the cement paste from old concrete. It will result in the inferior material properties of recycled aggregate concrete. Presently, the mix design with RCA was developed to get the desired amounts fly ash and recycled aggregate. The objective ofthis study is to evaluate material properties of concrete containing varying amounts fly ash and RCA. In the beginning, casting of different mould having different ratio of fly ash

2013-11-1  Also, the use of fly ash improved the flowability of recycled aggregate concrete. The strength test results showed that the higher ratio of recycled aggregates generally caused the lower compressive and tensile strengths of concrete. However, the cases with 30% recycled aggregates showed only slight compressive strength reductions.
