Abstract:: ... Hazardous wastes are usually used in the Portland cement production in order to save energy, costs and/or stabilize toxic substances and heavy metals inside the clinker. This work focus on the stabilization/solidification on chromium (III) wastes by C3A and C3A hydrated matrix. The immobilization rate of chromium in C3A and the leaching characteristics of the C3A hydrated matrixes containing chrom ...
