- ... Industrial wastes consumed by the preparation of building materials is a potential method to ensure the sustainable development. In this study, lithium slag (LS), as the by-product of lithium salts production, was treated by wet grinding process to prepare micro particles and used to expedite the early hydration of Portland cement (PC). The physical-chemical properties of micro-lithium slag (micro ...

- ... 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 ...
