Abstract

In this contribution, we evaluate mechanical characteristics of compressed and stabilized earth blocks. We have taken two samples of earth at Yaounde in Cameroon. After the identification of their properties, we have done compression’s experiments which allow us to determine the mechanical characteristics of those earth blocks. Afterwards, we have calculated the Young’s modulus, the resistance in compression and the deformation limit with the measured results. The numerical methods of approximation based on the elasticity-damaging coupling model allow also to evaluate the same mechanical characteristics and the comparison between the both methods are discussed. The evaluation of other characteristics like the damaging coefficient and the damage which are difficult to measure are also exposed.
