FIELD: building industry.
SUBSTANCE: invention relates to composite of sulfate-resistant Portland cement and can be used in industry of building materials and in building. Sulfate-resistant Portland cement comprises the following components, wt.-%: Portland cement clinker with the content of C3A up to 5% and the total amount of C3A + C4AF up to 22%, 60-90; calcium sulfate, 2-8; erupted volcanic alumosilicate rock with size of crystals below 200 mcm, the balance, being its structure is represented by minerals as solid solutions of augitic-anorthite order surrounded by glass-like interlayers. Invention provides preparing cement resistant to prolonged effect of sulfates.
EFFECT: improved and valuable properties of Portland cement.
