Abstract
The current study consists to introduce waste marble sand into the concrete formulation, as replacement of ordinary sand with variable rates (0%, 10%, 20% and 30%); the binder is composed of 90% cement and 10% tile polishing fillers. The properties of the concretes thus produced both in the fresh state (air content, density, and slump test) and in the hardened state (compressive strength) were measured. Obtained results showed that the introduction of 20% of waste marble sand in the presence of tile polishing fillers helps to decrease the air content and to improve compressive strength.
