•Calcined dredging sediments containing clay minerals show pozzolanic reactivity superior to siliceous fly ash•Flash calcination reduces surface area and roughness by forming spherical melt particles and particle agglomerates•Reactive Ca-enriched glass phase is formed as a flash calcination product
Dredging of ports, harbours and waterways generates vast amounts of sediments that find few applications and need to be disposed of. In the port of Antwerp, Belgium, each year 450,000 t (dry matter) of dredging sediments are mechanically dewatered and stockpiled. This paper investigates flash calcination of the clay-rich dredged sediments as a sustainable solution to develop novel pozzolanic supplementary cementitious materials (SCM) for blended cement.
