METHOD FOR REDUCING OR AVOIDING ALKALI-AGGREGATE REACTION IN SET CONCRETE

A method for reducing or avoiding an alkali-aggregate reaction in a cured concrete. The method includes providing a curable concrete mixture which includes alkali-sensitive aggregates (A), at least one organosilicon compound (B) and/or at least one siloxane (B2). Mass hydrophobization of the curable...

Beschreibung
Zusammenfassung:	A method for reducing or avoiding an alkali-aggregate reaction in a cured concrete. The method includes providing a curable concrete mixture which includes alkali-sensitive aggregates (A), at least one organosilicon compound (B) and/or at least one siloxane (B2). Mass hydrophobization of the curable concrete mixture is achieved by way of adding at least one organosilicon compound (B) to the curable concrete mixture prior to its curing thereby reducing or avoiding an alkali-aggregate reaction in the cured concrete.
