Abstract

Innovations in concrete technology are developing and increasing rapidly. Modifications were made in concrete research to produce concrete that is strong, economically valuable, and environmentally friendly. This can be done by using concrete waste as a concrete substitution material -which is coarse aggregate- and slag waste as a concrete substitution material for cement. In this research, the characteristic properties of these materials and the effects of their use on the strength of concrete will be studied. The compositions of Ground Granulated Blast Furnace Slag (GGBFS) varied by 0%, 25%, 50%, 75% with the coarse aggregate composition of 40% against natural aggregate. The use of 50% GGBFS gave the compressive strength of 24.8 MPa. The use of GGBFS will result the economic value of concrete and reduce CO2 emissions.
