The search for alternative piezoelectric materials is now being focused on alkali noibates, modified bismuth titanates, etc.
Among these materials, similar to (Na1/2Bi1/2)TiO3-based materials have the perovskite structure, and these materials show excellent properties such as relatively high piezoelectric properties.
Recent electromechanical studies [8] demonstrated that Ba(SnxTi1-x)O3 [abbreviated as BST] is basically suitable as environmental-friendly materials for electromechanical sensor and actuator applications.

With the composite development of spatial configuration and function of the arcade, it puts forward new requirements of materials and structures.
For the modern building materials applications such as steel or glass, and the introductions of structure system such as cable, film and inflatable, it enriches the morphological characteristics of the arcade building and reflects strong sense of times.
The use of Local Material.
In addition, local materials are usually used in conjunction with colors, such as red, orange and other vivid hues, which are extensively applied to detail treatment of the arcade commercial street to highlight lively atmosphere and popularity.

Introduction
Along with the development of grinding technologies, many new materials appear on the market, which special properties and applications result from their higher fineness.
One of these materials is microfine cement obtained as a product of ultrafine grinding of cement clinker, gypsum and special additives.
Materials and Methods Three commercial cements were used in this research: CEM I 42.5N cement produced by Russian manufacturer (OPC), microfine cement 1 (MFC-1) and microfine cement 2 (MFC-2).
Early-age properties of cement-based materials.
