摘要：Our research presents experimental results of chemical analysis and uniaxial compression tests cylindrical samples of four types of earth associated with 4% and 7% of cement dosage, allow to analyze the influence of the chemical elements of the clay and cement on the mechanical characteristics of earth blocks, namely: the Young modulus, the compressive strength and the deformation limit. The principal chemical constituents of clays of the four earth are: lime (CaO), quartz (SiO 2 ), dolomite (CaMg(CO 3 ) 2 ) and the alumino-silicate. These elements have amplified the improved behavior of the material by the addition of cement. Indeed, the strong presence of lime stabilized clay by quartz cementation and reacting the alumino-silicate with calcium hydroxide (Ca(OH) 2 ) in the presence of water, to form compounds with binding properties and the cement matrix to strengthen links between the grains of earth
