Abstract
The frost-de-icing salt-resistance of concrete structures is improved by applying to the surface of the concrete an aqueous alkali silicate solution comprising ______________________________________ slilicic acid (calculated as SiO.sub.2) 30-32 moles alkali metal ions (calculated as Na.sup.+1) 23-24.3 moles C.sub.1 -C.sub.3 alcohol (calculated as ethanol) 2-2.1 moles carbonate (calculated as CO.sub.3.sup.-2) 1.6-2.1 moles water at least 400 moles. ______________________________________
