Özet:

In this study, cementless mortars are produced with activation of waste marble dust, a waste material disposed from stone cutting plants, The influences of waste glass powder and calcium aluminate cement on the physical and mechanical properties of the mortars. For this purpose, mortar mixtures are composed replacing 10%, 20% and 30% of waste marble dust by waste glass powder and calcium aluminate cement separately and also together at the 5%+5%, 10%+10% and 15%+15% proportions by weight. The flow table, unit weight, ultrasound pulse velocity, flexural strength and compressive strength test are performed on the mortars. The highest mechanical properties are achieved on the mortars including 10%+10% waste glass powder + calcium aluminate cement by waste marble dust. The flexural and compressive strength of these mortars are 4.7 MPa and 26.3 MPa at the age of 28 days, respectively. The experimental results showed that substituting waste glass powder as a silica source and calcium aluminate cement as a source of alumina instead of marble dust, increased the recovery potential of waste marble powder through cementless mortar production.
