Mechanical Characterization of Building Materials Developed from Diamniadio Swelling Clay

Article Preview

Abstract:

This study focused on the valorization of swelling clay from Damniadio. This swelling clay is extracted during construction and dumped in the wild. The aim of this study was to valorize this clay in construction in order to produce bricks strong enough to be used in construction. The physical properties of this clay were evaluated, as well as the mechanical performance of the bricks produced. Finally, a model of a building component was produced using Autocad and Graitec OMD software. Compressive strength and tensile strength values ranged from 1.82 MPa to 30.24 MPa and from 0.14 MPa to 1.83 MPa respectively for raw earth bricks, and from 2.31 MPa to 40.6 MPa and from 0.15 MPa to 2.29 MPa respectively for kiln-dried earth bricks. The modelling of these bricks has thus shown their potential for use as load-bearing structures, making them both more environmentally friendly and more economical in a context where the purchase of concrete will be more expensive than the extraction and processing of clay.
