以苏州滨湖新城地下空间工程中所用的 C35\C40\C45三种强度等级的混凝土为研究对象，系统研究了新型 CaO 类膨胀抗裂剂对不同强度等级混凝土自收缩的补偿效果。结果表明，新型 HME?-Ⅴ混凝土高效抗裂剂对不同强度等级混凝土的自收缩均有明显的补偿作用，强度等级越低，补偿效果越好。
以囌州濱湖新城地下空間工程中所用的 C35\C40\C45三種彊度等級的混凝土為研究對象，繫統研究瞭新型 CaO 類膨脹抗裂劑對不同彊度等級混凝土自收縮的補償效果。結果錶明，新型 HME?-Ⅴ混凝土高效抗裂劑對不同彊度等級混凝土的自收縮均有明顯的補償作用，彊度等級越低，補償效果越好。

The three strength grade concrete including C35, C40 and C45 used in Suzhou Binhu New City Under-ground Space are researched in this paper. The workability, mechanical properties and autogengous shrinkage compensa-tion effect of them with or without the new CaO expansive agent have been studied. The results indicate that the HME? -Ⅴhigh cracking resistance agent has an excellent ability to compensate the autogenous shrinkage of the three strength grade concrete and the lower the concrete strength grade, the better the compensation effect.
