The dissoluble corrosion of Guangzhou metro engineering concrete in direct current was studied by an accelerated DC dissolving test of the residue mortar and correlating it with concrete.

Brief description on the winter construction of the concrete engineering;

Comment on construction quality control of shear wall structure concrete engineering;

The prevention and control of shrinkage cracks in concrete engineering;

The schedule of the concrete construction progress of the Permanent Ship-lock of the Three Gorges Project;

Some common quality problems often occur during concrete construction and these problems will directly influence engineering quality and structure safety.

Real-time dynamic emulation for construction of hydraulic concrete works;

Connecting with the actual engineering,this paper introduces the construction of the frame beam with higher from-erection,large span and overweight load,and emphatically expounds the steel-pipe bent supporting system,concrete works and deflection and crack control.

Connecting with the construction techniques of the concrete works,this paper discusses on the problem of the quality control of the concrete works from the concrete materials quality control,mixture ratio,mixing,transporting,pouring and curing and the forms removal,etc.

Prevention of constructive quality common diseases of concrete project;

Quality guarantee measures of concrete project with cast-in-site shear wall;

Application in projects demonstrated that addition of a certain amount of UNF-2 high range water reducing agent in concrete project reveald apparent economic benefits.

This paper discusses the supervisions in the construction preparatory stage,construction stage and acceptance stage,emphatically probes into the measures adopted in the reinforced bar work and the concrete work in the construction stage,and points out the main checking contents of the supervision in the winter construction.

Based on the engineering of formwork,reinforcement work and concrete work,this paper analyzed and discussed the managementmeasures of constructional safety and control points of safe techniques in order to promote the safety,efficience and continuance of construction.
