Abstract: Traditional constructions of the Sudano-Sahelian zones are mostly made from earth. However, these structures sometimes show early deterioration when they are not mixed with other materials. Mixing the earth material from termite mounds with straw Hyparrhenia hirta (L.) and suksuki) and snail shell powder after bringing it to a temperature of 700°C and sometimes with cow dung indicates the composition of our basic materials. Five mixtures were prepared with different percentages of its components: 2.5% straw or 62.5g for the first mixtures; 1.5% or 37.5g for the second mixture, 0% or 0g for the third mixture, 2.5% of straw, or 62.5g; 2.5% cow dung, i.e., 62.5g for the fourth mix and 1.5%, i.e. 37.5g snail shell combined with 1.5%, it’s either are use that is 37.5g cow dung for the fifth mixed. The submission of all these mixtures to mechanical tests in order to study their behaviour have shown that the compressive strength varies from one mixture to another and could therefore constitute a means of improving the mechanical behaviour. Of the different samples for which the average compressive strength increased from 1.131542 MPa for the first mixture to 8.863744 MPa for the fourth mixture.
