Review article

The article presents the results of a study on the processing of man-made raw materials (salt slag) from aluminum smelting. A technological process is proposed, the target product of which is an effective accelerator for lime-based building mixes` setting. Data on the chemical and mineral composition of slag are given. A basic technological scheme for processing man-made raw materials has been developed. Laboratory approbation of the proposed technological process was performed. The efficiency of using the obtained accelerator on building mixes is shown. The results of the study can be used for the design of building mixes for various purposes based on lime, including those intended for performing restoration work.
