STUDY OF THE MECHANICAL PERFORMANCE OF THERMALLY TREATED MARINE SEDIMENTS ON CEMENTITIOUS PRODUCTS

Abstract

The objective of this inquiry is twofold: firstly, the harnessing of this prodigious quantity of refuse, and secondly, to assess the mechanical efficacy of these sediments in cementitious formulations. The valorization of marine sediments treated at temperature 700°C in cementitious products was carried out in order to evaluate the behavior of cement mortar during the substitution of cement by different concentrations of marine sediments. During the mortar preparation process, marine sediments treated with three different substitution rates (10%, 20%, 30%) of CEM I 52.5 Portland cement were used to replace an equivalent volume of cement. The experimental results show that calcination at a temperature of 700°C with a concentration of 10% gives better results and gives a cement compound with better mechanical properties.
