水泥混凝土机场道面收缩裂缝的质量控制

Quality Control of Shrinkage Cracks in Cement Concrete Airport Pavement

结合上海浦东国际机场二期水泥混凝土道面施工,从原材料及配合比控制、拌合站用水量监控、振捣密实性控制、做面质量控制及加强初期养护等方面,采取各种预控措施避免形成裂缝,确保混凝土质量。

Combining the construction of cement concrete pavement in Shanghai Pudong International Airport,engineers adopt some effective measures to control cracks,such as the control of mixing ratio,the supervision of water consumption, the control of concrete vibrating,the quality control of float work,and the enhance of initial curing,etc.
