Abstract

The invention relates to inventive air-entraining admixtures for concrete and mortar mixtures, based on resin soap, characterised in that they contain SO3H groups in addition to the carboxyl groups that are present in the oleoresin acid skeleton. In relation to known air-entraining admixtures, the inventive products produce smaller air pores, a favourable pore distribution and increased pore stability. In addition, they are less sensitive to water hardness in terms of the formation of precipitation.
