Keywords: Template without demolition; RPC; new template structure; new building materials
Abstract: Innovation of material and function represents the direction of contemporary architecture template development.
Based on the study results of domestic and foreign building templates, a new type of template structure—Steel fiber RPC (reactive powder concrete) column-template without demolition is presented taking account of the characteristics of template materials and construction methods.

It was found that the use of zirconia as matrix material does improve the toughness and strength compared to alumina based composites whereas the drawback of zirconia based materials concerning machinability and lower hardness can be only partially compensated by adjusting the titanium carbide content.
Electrical discharge machining (EDM) is an established process for machining of materials with high hardness such as hardened steel or cemented carbides for mold design and construction.

Pore distribution was regular three-dimensional
geometric figure when D≤3, but when D>3, pore distribution of materials have been rather
complicated and irregular, three-dimensional figure of Euclidean geometry can't be used to
characterize spatial distribution, we can only use D [7].

Furthermore, taking waste polyester fiber materials as an example, economic cost analysis is used to assess the feasible ways in recycling waste fiber materials.
The recycling process of waste fiber materials could be divided into two parts: one is that waste fiber materials turn into recycled fibers, and the other is the use of recycled fiber process.
The Model of Three Elements in Classifying the Waste Fiber Materials The classification standards of waste fiber materials aren’t unified currently in home and abroad.
