The purpose of this study is to determine the feasibility of the partial replacement of cement with recycled fines in a high performance concrete whose purpose is to minimize the use of Portland cement and reduce the environmental impact of this waste. In the context of which, we used the fines of the granulated slag from El Hadjar-Annaba as a partial replacement of cement with substitution rates of 10, 15, 20%, and to study the behaviour in the fresh state (density and workability) and the mechanical performances (compressive and flexural tensile strength) and dimensional variation in the cured state, and then compared the results found with control samples of 0% substitution rate. Subsequent to which, it can be concluded that the introduction of recycled fines reduces the density and workability and improves the concrete's mechanical performance.

The percentage effect of slag on the behavior of a high performance concrete
