Abstract
The main objective of this article is to highlight the progress made in the development of new materials
that have been gradually used by humans until today. Of course, this progress must be associated with other
parameters in order to guarantee sustainable development. For this, today, it has become urgent to reduce the
consumption of cement by resorting to its partial or total replacement by other similar materials in order to reduce
CO2 emissions in our environment. This should certainly help to develop greener building materials. In this study, it
was decided to proceed with the partial or total replacement of Portland cement type CEM II/B-L-42.5N by slate and
lime that had not undergone any previous transformation. The results obtained revealed that the mortar whose substitution compared to the replacement of cement (100%) cement and sand (0/4) confers better kinetics than those of the series composed of (100%) cement and fraction rubble (0/1).
