Valorization of granite waste in the formulation of mortars

This study aims at the recovery of waste in the formulation of mortars, it is about granite waste recovered from commercial points of sale. To do this, a series of tests was carried out to study the possibility of using fines from granite waste in the form of addition in the formulation of the mortar with optimization of the dosage. The results obtained show that the partial replacement of cement and sand by granite with dosages 10%, 20%, 30% and 40% gave acceptable mechanical strengths (compressive and tensile) compared to the composition of the control mortar. The results of degree of hydration obtained during the ATG analysis confirmed the results obtained during the mechanical strength test.
