Experimental Study on Polycarboxylate High-performance Superplasticizer Use in Tunnel Segment Li Feng1, a, YuCe Wang2,b 1 Department of Civil Engineering, Shaoxing University, Shaoxing, Zhejiang, 2 China railway 23th construction bureau rail transit Co.Ltd.
Problem Put Forward Though a large number of Polycarboxylate superplasticizer engineering practice in production and engineering problems and solutions at home and abroad have proved that promote the use of polycarboxylate superplasticizer is the necessary requirement for high-performance concrete quality.
Nearly two years of practice and large-scale engineering applications prove that the polycarboxylate superplasticizer have comprehensive performance advantages but have been some new situations and new problems at the same time.
For example, the production process problems, product quality and stability problems, engineering problems and so on.

Introduction Electric discharge coating is a new technique of surface engineering developed in recent years, which can improve the performance of metal surface by using electrode made by a special process and a common machine tool of EDM [1-4].
In the process of EDM, the content of electrode, such as TiC, TiN and so on, can be deposited on the surface of metal parts to form a metal ceramic layer.

Based on the braiding process of composite, the axis direction stiffness/flexibility matrix, cell stiffness and engineering constants is acquired by the analysis of yarns and cell.
The yarn material, for example, carbon fiber, glass fiber, etc, can be selected, as well as the packing, such as resin, ceramic, etc.
