Improving rheological and mechanical properties of non-plastic clay soil from Bensmim region (Morocco) using bentonite additions: Suitability for building application

The present study aims to develop an innovative scientific methodology for adjusting the physicochemical composition of any clay soil make it appropriate construction applications. realized research was carried out on unexploited clayey extracted from Bensmim village (Morocco). Another sample "Extrabrick" brick manufactory also used as a reference since is produce high-quality bricks. Raw materials and geotechnical properties were determined. Results demonstrated that studied unsuitable raw material bricks production. This due its low plasticity resulting significant sand content, fraction, absence swelling clay. Therefore, improving our taken critical factor enhance this Different percentages bentonite, which known high plasticity, ranging 0 10%, added effect addition characteristics rheological mechanical analysis showed increasing percentage bentonite has beneficial In fact, 10% increase in yield stress, viscosity, mixture exhibited behavior very close sample. founded results fitted Herschel-Bulkley classical. findings suggest decreases flow index value increases consistency Furthermore, compressive strength went 5.3 MPa without additive 19.33 after addition. 23.83 MPa. These confirmed rheology could be powerful tool tune formulation materials.
