CONCRETE MIX PREPARATION METHOD Russian patent published in 2004 - IPC

FIELD: production of building materials.

SUBSTANCE: invention relates to methods of preparation of concrete mixes with additions used in manufacture of concrete and reinforced concrete articles and constructions. According to proposed method of preparation of concrete mix by mixing cement, fillers and active materials -calcium chloride and sodium chloride with mixing water, said active materials and mixing water are introduced in form of mineralized flows-wastes of nonferrous metal production at ratio of calcium chloride and sodium chloride of 1.01:1 - 1.4:1 at concentration of said active materials in flows-wastes being 7.8-17.2% and number of flows-wastes in concrete mix being 1-5% of mass of active materials in mass of cement.
