FIELD: industry of building materials. SUBSTANCE: invention refers to production of wall structural material based on secondary gypsum dehydrate-waste of porcelain-faience production. Starting material mixture to produce water-resistant building material includes secondary gypsum dehydrate, quicklime, Portland cement and water. Slaked lime in the form of saturated solution is utilized in the capacity of quicklime. Starting material mixture contains following proportion of components, mas.%: secondary gypsum dehydrate, 65.0-75.0; Portland cement slurry, 10.5-13.5; slaked lime in terms of dry lime, 0.0135- 0.019; water, the balance. EFFECT: raised water-resistance and strength of material, decreased energy consumption for production of building materials. 1 tbl
