摘　　要：由于混凝土泵送剂由多种外加剂和改性组分复配而成,而且水泥和掺合料性能变化大,泵送剂的使用效果受到的制约因素复杂,有时甚至还会导致严重的工程事故。文中结合试验数据、实践调查结果和标准修订情况,讨论泵送剂在商品混凝土中的应用技术难点,并对商品混凝土中安全高效应用泵送剂的技术要点进行深入探讨。The efficiency of applying Concrete Pumping Agent （PA） in ready-mixed concrete depends on many other factors besides PA itself because PA consists of several gradients and there is compatibility between PA and cement and/or mineral admixtures. From the point of the technique, the difficulties of applying PA in ready-mixed concrete are discussed based on the experiments data and on-site phenomena, and the suggestions for the safe and efficient application of PA in ready-mixed concrete are supposed.
