Dredged sediments as an alternative resource for sustainable cementitious mortars: application of Sekkak dam sediments in Algeria.

Year: 2026

Type: article

Abstract: This paper investigates the effect of incorporating calcined sediments (CS), obtained by heat treating of Sekkak dam sediments in Algeria, as a supplementary cementitious material (SCM), on the durability properties of mortars. Mortars with various proportions of Portland cement substituted with CS were tested. The experimental program covered compressive strength, water porosimetry and accelerated carbonation. The results show that cement substitution by CS improves the compressive strength of mortars, with an optimum content of 15% for achieving the best compressive strength. The incorporation of CS in mortars reduces their total porosity and resistance to carbonation due to the consumption of portlandite by pozzolanic reactions. Additionally, mathematical equations were developed to establish a correlation between the mechanical and physical properties of mortars based on different CS content.
