摘要
北京宝鼎广场刚性防水屋面施工中，通过合理选择混凝土配合比和预留分格缝，减少因混凝土自身的徐变、基层不均匀沉降、干缩和温度变形而产生的裂缝，并提高了混凝土自身的密实性。
The waterproofing rigid roof construction of the Beijing Baoding Square project has been carried out the following technological procedures namely:1,proper selection of an appropriate concrete mixing ratio 2,prearrangement of an adequate construction joint 3,reduction of concrete-self creep 4,elimination of non-homogeneous settlement 5,elimination of concrete cracks in dry-contraction and temperature-deformation and eventually 6,promotion of concrete's compactibility.
