ABSTRACT
Concrete is the global construction industry's most critical and consumed construction material. The use of two types of coarse aggregates, Crushed granite and local coarse aggregate, is examined in this study. Compressive strength is the most vital property of concrete. This research utilized two coarse aggregates: crushed granite and local coarse aggregate. Sharp sand is the fine aggregate. An initial laboratory examination was conducted to establish the appropriateness of utilizing the aggregates for construction purposes. Slump tests were investigated. Mix ratio (1:2:4) was used for this work, and mix structures were analyzed using the absolute weight technique. A total of 18 cubes (150×150×150mm) were cast to permit the compressive strength to be observed at 7, 14 and 28 days. Test results revealed that concrete produced from local gravel has better workability than crushed granite. Concrete produced from granite aggregate produced higher compressive strength at all periods. Compressive strength patterns were suggested as a result of age at curing.
