Physical characterization of excavated soils in diamniadio-senegal

The building is an object of concern in terms of health, energy consumption and environmental impacts. With more than 40 % of the worlds energy consumption and high CO2 emissions, the building sector is among the most energy-intensive sectors. An in-depth analysis of the building sector shows that Concrete, the material currently most used in Senegal is unsuited to the climatic conditions of Sahelian countries. In addition, cement production consumes a lot of energy and is a source of greenhouse gas emissions. Faced with environmental and energy concerns, the choice of appropriate materials is a key to limiting environmental impact and ensuring a healthy and comfortable indoor environment. This is how a sustainable approach using local clay resources for the production of clay bricks was implemented. However, the use of swelling clays is the source of significant problems in construction. Thus for a good prediction of the mechanical and thermal behavior of a material, it is important to determine its physical properties. This is why our study focuses on the physical characterization of the excavated soils of Diamniadio.
