原则将混凝土装入模具中，并用夯实机夯实。固结量即称为“压塑性指数”。
PRINCIPLE Concrete is placed into a mould and compacted by a rammer. The amount of consolidation is expressed as a compactibility index.
结果表明，疲劳裂纹是在残余拉应力和循环压应力作用下萌生和扩展的，压塑性变形是裂纹萌生和扩展的必要条件。
The result shows: the local residual tensile stress and cyclic compressive loading thrust fatigue crack initiation and propagation in the size of compressive plastic zone.
范围本标准对混凝土压塑性指数的测定方法(在预计的坍落度小于10 mm，并且骨料的标称粒径不超过40 mm的情况下)作出了规定。
SCOPE This Standard sets out the method for determining the compactibility index, for concrete, where the expected slump is less than 10 mm and the nominal size of aggregate does not exceed 40 mm.
