METHOD OF MAKING ALL-PURPOSE SLAB Russian patent published in 2014 - IPC C04B28/30 B28B5/00 

FIELD: chemistry.

SUBSTANCE: invention relates to construction and specifically to methods of making slabs. The method of all-purpose making slabs involves mixing magnesia binder, organic filler, mineral filler and aqueous magnesium chloride solution, moulding articles, hardening and drying. The magnesia filler consists of two or more components, one of which is solid wastes from production of magnesia binder-based slabs and the second component is pearlite. Before adding to the mixture, all dry components are mixed to a homogeneous state, wherein components in the overall mixture are in the following ratio, wt %: magnesia binder 10-40, aqueous magnesium chloride solution with density of 1.1-1.3 g/cm³ 40-70, organic filler 4-15, mineral filler 2-20.

EFFECT: invention improved environmental safety of slabs.
