The blast furnace slag comes out of the blast furnace in liquid form at 1500°C. When cooled slowly, in the open air, the crystallized blast furnace slag is obtained. Its uses are generally the same as those of natural rocks. The purpose of this article is to measure the influence of the substitution of Diack basalt aggregates by blast furnace slags (FABRIMETAL slags) on the compressive strength of hydraulic concretes. For this two reference concrete mixtures were used. The first concrete mixture (concrete 1) is mixed with basalt of Diack only, and the second concrete mixture (concrete 5) is mixed with FABRIMETAL slags only. Then basalt substitutions by slags were performed on the concrete 1 at 10%, 25% and 50%. The results obtained showed that slags influence the strength of hydraulic concretes formulated with basalt of Diack by decreasing it. The 28-days compressive strength of concrete 1 drops from 28.8 MPa to 24.8 MPa for 10% substitution, 24.4 MPa for 25% substitution and 21.8 MPa for 50% substitution. However, given the low dispersion of the results obtained (Standard Deviation = 2.28), the substitution of basalt by slag is still possible provided that hydraulic concrete is optimized with additives or a slight cement overdose.
