Some Aspects about Adsorption of Polymer on Cement Grain Shiyun ZHONG1,a, Dongdong HAN2,b and Jinmei LI3,c 1Key Laboratory of Advanced Civil Engineering Materials of Ministry of Education, Tongji University, Shanghai 201804, China 2School of Materials Science and Engineering, Tongji University, Shanghai 201804, China 3Sinoma Research Institute, Sinoma International Engineering Co.
For example polycarboxylate ether-based superplasticizers (PCEs, negative charged) are strongly adsorbed by positively charged materials while poorly adsorbed by negatively charged materials [8].
Noticed that negative charged PCEs will be also, though poorly, adsorbed negatively charged materials [8], and again the poly(ethylene-co-vinyl acetate) (EVA) particles are obviously deposit on the C3S surface at first minutes after mixing as observed under soft X-ray microscopy [11], although both EVA particle and C3S grain are believed to have negative charge.

This kind of architecture configuration should not only express culture from structure, material, space , but the integrated parameters of environmental and contextual factor should be also added to create sustainable architectures of more social significance should join the environment and context.
First, set three basic square body on the basis of functional requirement of building, material properties. (0.5 M, 1.0 M, 1.5 M),based on the building functional requirements and material properties.
In this design, designer used several extremely simple member unit to diverse a variety of architectural epidermis and structural surface, and try to more effectively show sustainable characters which reduce material waste, easy maintenance and construction cost through standard construction.

Introduction 2A70 alloy is an important part materials for the aviation engine due to its light weight, high strength, good machining, good corrosion resistance, especially its strength and creep resistance to maintain lasting a long time in the high temperature.
This mode of production has lead to waste on human, material resources and financial resources and stable surface quality is hard to be obtained.
It relates with some factors such as the tool of geometric parameters and materials, work-piece material, cutting parameters, system stiffness and cutting process.

In the shaving process, removing material from work gear surface causes hardening on work gear surface.
It is due to unwanted friction and material flow by the action of top land of serration.
In other word, most of material can be removed in first few cutting cycles.
It means that most of material will be removed after first and second cutting cycle.
