The Physico-Chemical and Mineralogical Analysis of Clays in Algeria

Abstract

The physico-chemical and mineralogical analysis of soils in civil engineering aims to understand the properties and behavior of their components in the field of construction and engineering. Mineralogical characterization makes it possible to identify the minerals present in clays, such as kaolinite, illite, montmorillonite, etc. This is essential for understanding the swelling, retraction and plasticity properties of clay. Knowledge of the chemical composition makes it possible to evaluate their chemical reactivity, their potential for alteration, and their compatibility with construction materials.
