In this study, reused coarse aggregates (RCA) came from demolition wastes collected from a dump site in Gaborone, Botswana, were promoted in place of natural rude aggregates to make concrete. Construction waste is some type of rubbish produce during the construction process. Various administration agencies have sure definitions. CD waste is created during the building, remodeling, perpetuation, and destruction of dwellings, large building structures, roads, bridges, piers, and dams. In a premature study, an in-depth and all-encompassing analysis of prior research into the evaluation of the strength of factual integrating aggregates from destroyed wastes was conducted, and it was concluded that skilled was a stark dearth of results from the South African substitute-continent, including Botswana. With reference to the unaffected coarse aggregate, RCA substitute levels of 0%, 20%, 40%, 60%, 80% and 100% were utilized and the results of hardened actual tests for compressive and flexural strengths were got. The compressive and flexural strengths of reused aggregate concrete (RAC) were observed to decline accompanying increasing substitute levels of natural rude aggregates using RCA. It was determined that RCA commit only be used as a biased replacement for natural aggregate in factual up to a particularized limit. It was also found that the unfavorable qualities of RCA were generally caused for one quantity and quality of the fastening mortar.
