Aiming at air-bubbles and water-bubbles on the surface of concrete,and on base of many years practice,the paper concludes some methods of reducing air-bubbles and water-bubbles on concrete surface from the following aspects: beating during construction,proportion controlling of raw material,mode controlling and so on,it aims to make concrete surface beautiful,solid and clean.

Optimization of formwork system of cast-in-place concrete for major structure of high-rise building;

In this article,authors show the construction process of inclined beams,especially the formwork system and construction methods.

Integral steel platform formwork system is a new kind of formwork system adapting the construction need of super high rise buildings.

Key points in the design of the high strut follow board system;

It analyzes the characteristics and application dimension of every follow board system,represents the design idea of compound plastic inside lining follow board,discusses its composition and construction technique,and generalizes the related matters need attention in application,which will meet the purpose of increasing the integral firmness of structure.

This paper introduces the processing of the and laminated bamboo plywood form system and its consolidation service, and emphatically expounds the practice of the joints in detail, which includes the type selection of the forms and the supports and the arrangement of the forms, and puts forward some matters needing attention in the construction.

There are slab-beam form system,flat-slab brace sys-tem,variable radius form system,light form system,cylinder form system,manual assembled form system,heat insulation form system and etc.

Several new form systems have been applied in the construction of the National Theatre.

The chain-up template system which was designed in combination with engineering has been successfully resolved the problem.
