预拌混凝土的出现解决了现场搅拌混凝土的不足,但在应用的过程中也产生了一些问题,如混凝土的早期开裂问题一直是大家关注的重点,也是解决的难点,尤其是表面系数大的板、墙以及大体积混凝土施工工艺不良等原因造成的混凝土开裂问题,引发了很多不必要的纠纷。因此,找出混凝土早期开裂的原因,从而采取相应的防治措施是解决问题的关键。本期特别策划再次就混凝土早期开裂问题的成因和防治措施邀请专家给出意见和建议,希望能给广大从业人员提供参考。
The emergence of ready-mixed concrete to solve the problem of on-site mixing concrete, but also in the application process has some problems, such as early cracking of concrete has been the focus of attention, but also solve the difficulties, especially the surface coefficient of the board , Concrete wall construction and poor construction of concrete caused by cracking and other reasons, caused a lot of unnecessary disputes. Therefore, to find out the reasons for the early cracking of concrete, so to take appropriate preventive measures is the key to solve the problem. This special planning once again on the cause of concrete early cracking problems and prevention and treatment measures invited experts to give comments and suggestions, hoping to provide reference for the majority of practitioners.
