The research results of the stability of air-entrainment in the case of innovative air-entraining multi-component CEM II/B-V are presented in this paper. Compatibility with innovative cement air-entraining CEM II/B-V plasticizers and superplasticizers were evaluated in terms of stability of air entrainment and maintenance of consistency for one hour of mortar according to PN-EN 480-1. The research results indicated that in case of a significant increase in the degree of liquidity of the air-entrained mortar or concrete made of participation of the innovative, air-entraining multi-component cement CEM II/B-V, first and new generation superplasticizers based on modified naphthalene, and then modified phosphoramidate should be used. The new generation superplasticizers based on polycarboxylate, polycarboxylic ether and acrylate cause a significant increase in the air-content of the air-entrained mortar and concrete.
