Eco-concretes are essential to integrate into civil engineering for environmental reasons. Beams, which are load-bearing elements of civil engineering structures, are subjected to mechanical and thermal loads. In this study, mechanical and thermal deformations are analyzed on beams reinforced with Pottery powder at different concentrations. The thermoelastic properties of the eco-concrete are obtained using the Mori-Tanaka model. The studied deformation takes into account the shear effect introduced by a mathematical function. The principle of virtual work is used to establish the equilibrium equations, and then Navier's solutions are applied to solve the mathematical problem of thermomechanical bending. It is found that as the concentration of Pottery powder increases, the mechanical deformation decreases. Eco-concretes also show strong resistance to thermomechanical behavior and the influence of temperature. Furthermore, it is shown that it is possible to incorporate up to 30% of aluminosilicate waste in the form of Pottery powder................ Keywords:..........
