The effect of treated sediments on self-compacting mortars properties using design of experiments

Résumé

A very significant quantity of sediments are dredged all over the world. Many previous studies demonstrate that this materials can be used as a cementitious supplementary material. In this paper, the raw sediments were dried, sieved, and thermally treated in order to eliminate organic matter and activate the minerals. The physical, chemical, and mineralogical properties were determined for the raw and treated sediments. Blended self-compacting mortars were formulated by substituting partial Portland cement with sediments. The compressive and bending strength, and dynamic modulus of elasticity were tested for different deadlines (7, 28, 60, and 90 days). The fresh properties of the pastes were investigated as well. The results shows that sediments can be used as a replacement of cement up to 12% of the volume of cement while maintaining the fresh compactibility properties. © 2018, Centro de Ciencias de la Atmosfera, UNAM.
