摘要:
A fluidizing admixture for use with sprayable cementitious compostions, the admixture consists of 2-phosphonobutane-1,2,4-tricarboxylic acid and at least one selected polymer derived from ethylenically-unsaturated mono- or dicarboxylic acids. Citric acid may optionally be present. The admixture has good fluidizing properties and outstanding shelf-life.
