Аннотация: Aluminum and iron hydroxides, formed in the stone during the hydration of cement with the addition of special slags, significantly improve the properties of concrete. The addition of low-basic calcium aluminates CA2 and CA6 in the form of high-alumina slag, which releases a large amount of Al(OH)3 during hydration, increases the stПоказать полностьюrength, density, water resistance, frost and corrosion resistance of hydraulic concrete. A compressed mixture of concrete scrap and high-alumina slag based on low-basic aluminates makes it possible to obtain durable and frost-resistant materials and pavement structures. A special nickel slag of increased basicity in a mixture with Portland cement ensures the formation of ferric hydroxide during hydration. Concrete on such Portland slag cement shows frost resistance for more than 500 cycles without special measures. © Published under licence by IOP Publishing Ltd.
