The results of the physico-chemical studies of the phase composition of the glass-containing slag Portland cement increased corrosion resistance. It shown that with increasing slag content in the binder reduces the amount of highly basic calcium silicate and an increasing number of low-key hydrosilicates calcium and hydrogelenite. The presence of the optimal amount of glass powder (5 wt. %) promotes the synthesis of corrosion-resistant calcium-sodium zeolite. Marked new formation composition enhances corrosion resistance of the artificial stone in 5% solution NaCl and Na2SO4. The highest values of corrosion resistance coefficient – 1.22-1.26 and 1.88-1.98 in 5% solutions of salts characterized artificial stone obtained by slag Portland cement with slag content of 40%. The results should use to develop protective coating compositions of concrete and reinforced concrete structures hydromeliorative and transport purposes.
