Article: Study of the influence of water saturation on main mechanical properties of laterite dimension stones from Burkina Faso Journal: International Journal of Structural Engineering (IJSTRUCTE) 2025 Vol.15 No.1 pp.1 - 28 Abstract: This scientific paper presents the findings of a study on the hydromechanical behaviour of laterite stones (LS) from four quarries in Burkina Faso. The study examines the impact of water saturation on the compressive strength, tensile strength, Young modulus, and Poisson's ratio of the stones. The results indicate that water saturation significantly reduces the mechanical characteristics of the stones, with up to a 71% decrease in compressive strength and a 61% decrease in Young modulus. The study also highlights the influence of pore size and distribution on strength loss and identifies correlations between physical and mechanical properties under dry and saturated conditions. Furthermore, it reveals that the behaviour of LS varies depending on block size, with large blocks exhibiting brittle behaviour and smaller blocks showing ductile behaviour. The study also discusses the influence of the hydric state on the behaviour change of the stones. Additionally, it identifies novel correlation functions between mechanical and physical properties under dry and saturated conditions, which can provide an alternative to costly laboratory experiments. The study offers valuable insights into the mechanical behaviour of stones under different hydric states and provides practical implications for selecting and using stone materials in various environments.
