Mechanical and thermo-physical characterization of mortars made with uncontaminated marine sediments

In a context of sustainable development, civil engineering must increasingly use recyclable materials to preserve natural resources. Sediments could be solution in the their recovery several areas. Uncontaminated marine sediments were used partially substitute sand aggregate formulation mortars. Five mortars manufactured with different percentages substitution. Physical, chemical, mineralogy, and mechanical characterization carried out order investigate possible impact cemented-based materials. The strengths elastic modulus analyzed. hydration kinetics studied at temperatures. acceleration chemical reactions was also assessed through determination apparent activation energy Finally, microstructure two formulations observed by Scanning Electron Microscope (SEM). Results show drop properties increase percentage This can attributed composition total porosity mixtures. measured heat released sediment content. result suggests an additional activity linked presence within matrix.
