Based on the difficulty analysis on the whole body casting of concrete beam and plate with different strength levels, it is necessary to take construction process planning into consideration.
通过对不同强度等级的梁、板混凝土同时浇筑的困难分析 ,进而建议不同强度等级的梁、板同时浇筑混凝土时 ,需考虑做浇筑工艺过程设计 ,并提出浇筑工艺过程设计的要点和步骤。
The main problems existing in <The Test and Evaluation Standard of Concrete Strength>(GBJ 107-87)are:1)it is too loose and does not reach the design required strength class;2)the three methods which are adopted are of different strictness and they have unreasonable aspects.
《混凝土强度检验评定标准》(GBJ 1 0 7- 87)的主要问题 ,一是偏宽 ,达不到设计要求的强度等级 ;二是强度合格评定采用的三种方法 ,宽严不一致 ,且都有不合理之处。
construction and supervision,this paper discusses the method to control the concrete strength class strictly and poses the suitable control measure to reach the target of high quality concrete engineering.
