摘　　要：分析了水泥化学和物理特性、外加剂本身、掺合料的种类和掺量及集料对相容性的影响;并从外加剂的作用机理出发总结了外加剂对浆体流变性(流动性与稳定性)的影响;同时分析了相容性与混凝土耐久性之间的关系;提出良好的相容性是制备高性能混凝土的基础,对建立相容性定量评价方法做了初步探讨。The effects of physical and chemical speciality, superplasticizer characteristic, species and dosage of admixture,carpolite and sand on compatibility were studied. Also, the effect of superplasticizer on paste rheology （fluidity and stability）from mechanism, and the relation between compatibility and concrete durability were analyzed. It indicated that excellent compatibility was the base of making high performance concrete, and discussed how to build quantitative evaluatation way of compatiblity initially.
