Experimental Study on the Measurement of Some Physical Quantities for the Durability of Concrete under Hot-Arid Climatic Conditions

Abstract

The synthesis of work carried out on the behavior of concrete subjected to temperature has allowed us to highlight certain physical phenomena, which can appear in particular during the degradation of the material. Among these phenomena are the evolution of porosity and apparent density during heating, which are two important physical quantities of cementitious materials, and they play a major role in the durability of concrete. In this context, the main objective of this experimental study is to improve the understanding of the behavior of tested concrete subjected to different temperature gradients, for hot and arid regions. To achieve this, some tests related to durability (open porosity and apparent density) were carried out in order to identify the origin of any disparities that were observed following the analysis of mechanical results.
