چکیده
|
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 (sio2),dolomite (camg(co3)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.
