The main object of this study is to optimize the use of crushed sand from basalt aggregates and sand dune in hydraulic concrete. In this sense, we have studied a series of tests, of partial and/or total substitution of sand dune by crushed basalt sand, with a W/C ratio (water/cement) of 0.49. The study consists to assess the rheological and mechanical properties of the concretes (C1, C2, C3, C4, C5, and C6) with respective substitution rates of (0%, 20%, 40%, 60%, 80% and 100%). The results are then compared and discussed. The best workability is given by sand dune concrete (C1). The mechanical resistance of C6 is superior to that of C1, on the other hand the workability of C1 is greater than that of C6. The mixes based on partially substituted aggregates give the best compressive strength performance compared to those based on fully substituted aggregates (C1 or C6). Maximum compression is obtained at 20%.
Author Keywords: Sand dune, Crushed sand, basalte and Substitution.
