    摘要： An admixture for modifying the fluidity of a cementitious mixture comprises a cement-dispersing agent which is an aqueous solution of polymer, in which solution an oxyalkylene-based defoaming agent is dissolved or dispersed in particles of no greater that 20 .mu.M diameter. The polymer is preferably a polymer which comprises units derived from unsaturated carboxylic acid monomer and the polymer is preferably prepared in the presence of the defoaming agent. Particular addition copolymers give particularly good results. The admixture permits good control of the fluidity of cementitious compositions and has extended shelf life.
