Use of recycled concrete aggregate in concrete a review

AbstractThe use of recycled concrete aggregate (RCA) in concrete as partial and full replacements of natural coarse aggregate is growing interest in the construction industry as it reduces the demand for aggregate In addition the use of RCA leads to a possible solution to the environmental problem caused by concrete waste and reduces the negative environmental impact of the aggregate Experimental study of concrete made with granite and iron powders as partial replacement of sand The experimental research conducted in this study showed the mechanical properties of concrete have improved when granite powder and iron powder were used as partial replacement of sand in specified percentages fine aggregates (sand
