Microstructure and Mechanical Properties of Steels

In order to understand the thermal behavior of the masonry elements submitted to high temperatures we need to know the variation of their thermal properties with regard to the temperature.Submitted to high temperatures clay brick masonry presents thermomechanical effects (as the variation of Young's modulus, the thermal expansion of the unit and the mortar, spalling, losses of resistance…) as well as variation of the properties of the material as result of its degradation.In this article the variation of the module of elasticity of the unit and the mortar is described with regard to high temperatures according to the state of the knowledge.In this article is also exposed the results obtained from the experimental program carried out on elements of clay brick masonry submitted to high temperatures in order to observe the variation of Young's module related to temperature.
