This work presents, firstly, the results of pozzolanicity tests on two varieties of clay, codified respectively ABD and ARD, taken at Débélé. In a second step, the physical properties of the mortars obtained from these two clays by substitution of cement at a rate of 20% are presented and discussed. The mechanical behaviour of the mortars shows acceptable variations with apparent densities between 1.800 and 2.090 g/cm3. The mechanical resistance is lower than that of the control mortar for hybrids based on raw clays, but those of hybrids based on calcined clays are higher than that of the control mortar beyond the 28th. These results attest to the pozzolanic character of the Débélé clays and constitute a contribution to their valorisation in the formulation of hydraulic binders |
