Description
The additions of supplementary cementitious materials are currently part of the latest developments in the production of cement, resulting in a significant improvement of the mechanical performances of cementitious materials. On addition to that, their use has as objective to reduce the clinker consumption so that to contribute in a simple and economic manner in solving the environmental problems. This experimental work consists to make a cement with mineral admixture while replacing a certain percentage of clinker by slag (0%, 6%, 10%, 20%, 25%, 30%, 35%, 40%, 50%, 65%, 70%, 80%, 85% and 90% ) in order to study its effect on the physico-chemical properties of cement manufactured with mineral addition and the mortar mechanical response. The physic-chemical properties of cement at anhydrous state and the hydrated state, as well as the characteristics of the mortars made at their bases, such as shrinkage, expansion, and the mechanical properties, have been studied. According to the experimental results obtained, it comes that the quantity of mineral additive (slag) and the chemical composition of cement manufactured are the principal parameters that influence on the variation of physico-chemical properties and the mechanical strengths (flexural and compressive) of the mortars tested.
