PHYSICAL AND MECHANICAL CHARACTERISTICS OF THE EARTHEN BARNS USED FOR FOOD CROP STORAGE IN THE NORTH-WEST OF BENIN (WEST AFRICA)

Atacora and Donga are two departments regarded as the barns of Benin. In these two regions, the surplus of food crops harvested by farmers is stocked in earthen barns whose primary construction material is kneaded clay soil with an admixture of vegetable straws (fonio, rice…) pounded beforehand. The following research is designed to scrutinize the variation of compression strength and/or tensile strength of the used earthen material with respect to the optimum straw content, and the fluctuation of the fracture related parameters.
