摘　　要：以P.O.42.5水泥为基础,通过骨料级配和多种外加剂的调整,研制出一种流动性良好、高强无收缩的ANG-II型灌浆料。选用优质骨料和最佳级配,配合高性能减水剂,使灌浆料初始流动度达300mm,半小时为280mm,并且利用二步膨胀机理,使材料的竖向膨胀率达0.4‰,使材料具有良好的填充性能。此外通过三次增强作用,使材料的28d抗压强度达93MPa,更加牢固耐久。In this paper, a kind of high flow, high strength, non shrink, cementitious grout was blended,basing on P.0.42.5 cement with well graded aggregates. With high water reducer adequate fluidity is got, and with two kind of expansion agents two-step expansion is got, still with three enhancing materials high compressive/break strength is got.

关 键 词：级配 二步膨胀 抗压强度
