HEAVYWEIGHT CONCRETE WITH STEEL SLAG AGGREGATES

Steel slag in different fragments was tested as aggregate for heavyweight concrete to produce concrete blocks, radiation shielding or other defense constructions. The mechanical characteristics of the proposed concrete were checked. Bond strength and rupture energy are enhanced. Compressive strength of 50 MPa has been achieved in concrete with steel slag and alternative cementitious materials (60% of Portland cement was replaced by fly ash).
