N2 - This paper presents the results of a study on the stability of the air-entrainment of innovative air-entraining multi-component CEM II/B-S with different types of air-entraining admixture. Plasticizers and superplasticizers compatible with air-entraining cement CEM II/B-S were evaluated in terms of stability of air entrainment and ability to maintain consistency for one hour in mortar according PN-EN 480-1. In the next stage of the research the influence of the most compatible SPs on air-entrainment and the consistency of fresh concrete according to PN-EN 480-1 were investigated. The research results indicated that in case of a significant increase in the degree of liquidity of the air-entrained mortar or concrete with innovative, air-entraining multi-component cement CEM II/B-S, plasticizers or 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.
