The influences of granite industry waste on concrete properties with different strength grades

The use of granite industry waste as a mixing material of concrete reduces not only the natural aggregate consumption, but also the solid waste disposal problems. This paper addresses the influences of recycled granite aggregate on the concrete properties. Both the low- (20 MPa) and high- (50 MPa) strength concretes were investigated for various sand replacing proportions with granite particles (namely up to 50 % by weight). The tests showed the...
