The Concrete used is made by the use of inorganic waste is called Green Concrete. There are more eco-friendly and are used as a means to promote the sustainable development of our planet. This paper is parallel to the Possibility of the use of by-products such as fly ash, pozzocrete, used foundry sand, etc, etc., in the implementation of the program. Green concrete is formed by the partial replacement of cement and fine Aggregate by their respective switches. This paper is concerned with the effect on the compressive strength of the concrete when the cement is partially replaced with pozzocrete P60, up to 30% by weight of cement and fine aggregate is replaced with the used foundry sand is a by 10%, 25% and 50% by weight of cement. For this study, five sets of mixing ratios were prepared. This study was carried out in order to study the function of the advantages of the partial replacement of cement and fine aggregate By their country.
