abstract={This study consists in experimentally determining a formula of mortar got from silty sands of Togo for the purpose of optimal mechanical properties. 1,443 4cmx4cmx16cm test tubes of mortars made from silty sands of 12 sites of extraction of Togo are prepared at variations of water and cement. The results show that for the water-cement ratio (E/C) of 0.5, the evolution of resistances in compression at 28 days of age (¦Ò<SUB>c</SUB>) increases exponentially to C/S and E/S ratios ranging between 0.311 to 0.512 and 0.156 to 0.256 (¦Ò<SUB>c</SUB>=ae<SUP>b1(</SUP><SUP>C</SUP><SUP>/</SUP><SUP>S</SUP><SUP>)</SUP>=ae<SUP>b2(E</SUP><SUP>/</SUP><SUP>S</SUP><SUP>)</SUP><SUP> </SUP>with 0.061&lt;a&lt;0.182, 11.08&lt;b1&lt;12.9 and 22.17&lt;b2&lt;25.80). They become stationary beyond these values (¦Ò<SUB>c</SUB>¡Ö19MPa to 35,45MPa). Two formulas of rich mortars (E/C=0.5, C/S>0.512 and E/S>0.226) and lean (E/C=0.5, C/S&lt;0.311 and E/S&lt;0.156) silty sands taken in Togo are therefore defined.},
