Method for rehabilitative and/or protective corrosion-inhibition of reinforcing steel embedded in a hardened concrete structure by means of surface-applied corrosion-inhibiting compositions

On object of the present invention is an agent for the reduction of the degree of shrinkage in hydraulic binders, whereby said comprises an alkanolamine of formula R&mdash;NH&mdash;(AOH) wherein R is hydrogen or a linear or branched aliphatic or cyclic C -C -alkyl group, and A is a C H -group or C H -group, alone or in combination with hydroxy compounds and/or ethers. Furthermore a method for the reduction of the dry shrinkage of binders such as cement, admixed cement, puzzolanas and thereof produced mortars and concretes by means of such a shrinkage reducing agent is described.
