A concrete, more especially a non-reinforced concrete has at least a residual amount of sodium fluorophosphate which reduces scaling of the concrete, when the concrete is subjected to freezing and thawing. A method to reduce scaling of concrete due to freezing and thawing comprises contacting the concrete with a system containing at least sodium fluorophosphate.
u béton, plus précisément du béton non renforcé, possédant au moins une quantité résiduelle de fluorophosphate de sodium qui réduit l'écaillage du béton lorsqu'il est soumis au gel et au dégel. Une méthode de réduction de l'écaillage du béton résultant du gel et du dégel comporte l'application sur le béton d'un produit contenant au moins du fluorophosphate de sodium.
