In this research, the compressive strength and modulus of elasticity of prisms made with hollow soil-CDW-cement bricks (50%-10%-50%, by mass), aged (530 days), joined by a 5 mm conventional laying mortar joint. The characterization of the soil and the mixture of Soil-Cement-CDW was carried out. Compressive strength, modulus of elasticity and failure mode of the prisms were evaluated. The efficiency factor of the prisms was 57%, an expected value consistent with other authors. The failure mode observed was traction in the bricks and subsequent propagation of cracks in the joints, presenting behavior similar to brittle rupture materials. The equations proposed by the Brazilian normalization for concrete bricks were the ones that were closest to the values found in this research. It should be noted, however, that the mechanical behavior of this type of masonry still needs to be better studied.
