The purpose of this paper is to investigate the feasibility of using basalt aggregates in concrete mixes. Concrete is the most important engineering material and the addition or replacement of some of the materials may change the properties of the concrete. In recent years a lot of research work has been carried out in order to obtain more durable and long term performance of concrete structures in the dynamic environment. An experimental program is set up to test the effect of basalt aggregate content and its combinations with lime stone with variation of percentages in concrete mixes. Different aggregate percentage combinations were used in this study for basalt and limestone (0%,100%) ,(25%,75%) ,(50%,50%) ,(75%,25%) ,(100%,0%) respectively. The laboratory investigation included measurement of compressive strength and workability. In addition the source aggregate properties were considered in this study: Los Angeles abrasion, specific gravity and absorption for coarse aggregates and fine aggregate. The result of this investigation indicate a general improvement in mix properties with the introduction of basalt aggregates in the mix.’
