The data were then analyzed using statistical package for the social sciences is used as a path analysis model to verify the hypothetical construction of the study.
The supply chain is an integrated manufacturing process wherein raw materials are converted into final and finished products, then delivered to consumers or end user.
Minimizing the generation of hazardous waste, recovery of valuable materials from the waste and preventing the environmental deterioration are some complex issues which require prime attention (G.

This means increasing research on new materials, that are sustainable, economic and ecologic, in other words eco-materials [1-4].
The aim of this study is to valorize two very abundant natural deposits in Algeria: ground natural pozzolan “PZ” and dune sand “SD” and to evaluate the effect of these powdered materials in cement-based materials.
