Influence of dispersion and content of mineral filler on the structure and properties of gypsum binder

The effect of dispersion on the structure and properties of gypsum binder and the content of mineral filler from industrial waste (15%) - crushed steel-smelting slag from the mass of gypsum binder was studied. With the introduction of the optimal amount of filler, in turn, it can significantly improve the macrostructure of the composite, increase the strength of the gypsum stone by 20%, despite the reduction in the consumption of gypsum binder up to 25%. At the same time, their strength characteristics are preserved, relative to the gypsum binder without filler. The resulting gypsum binder can be used in the manufacture of gypsum tongue-and-groove boards for the construction of partitions in rooms with normal humidity.
