Stabilization of contaminated canal sediments
Morocco has valuable assets in marine seaboards and resources. The Mediterranean coasts do more than attracting tourists. That is why it is imperative to reconcile economic development with the quality of the environment. The industrial area in Tangier (Morocco), situated in the south-east area of the city, is a primary source of sediment pollution in the canal which runs through the area and discharges into the sea. This paper studies the contaminated and untreated sediments from that canal. A physical, chemical, mineral and environmental characterization was made to evaluate its possible use as sand for mortar. The replacement of sand by sediment indeed reduces the mechanical strengths. The chemical analysis of leachates after leaching test yet show a certain stabilization of pollutants, specially heavy metals in the cementitious matrix.
