RE has considerable influence on the comprehensive properties of copper-based electrical contact materials.
Basically there are two types of contact materials.
SPS is referred to an advanced technology that is used to prepare and synthesize materials with different properties, like ceramics, composite materials, etc.
New materials such as nanometer blocks, bulk amorphous blocks, multi-dimensioned materials with composite structure and functional gradient are also processed through SPS [4-7].

Introduction In 1984, the Japanese scientists synthesised the heterogeneous materials-functionally gradient materials(FGMs)which was made of ceramic and metal.

There are limited available datasets on building materials as they are typically not transparent, and research is usually done to individual materials or components.
Unfortunately, construction activities consume as much as 40% of global energy and materials used, emitting about 35% of carbon dioxide [20] using 30% raw materials and 28% of landfill material as construction debris [6].
Although less toxic and safer materials such as sustainable and green building materials are available, they are not widely used.

Introduction Nanosized materials are a field that takes a materials science-based approach to nanotechnology.
In recent years, computer simulation technology as an effective method has been widely used in materials science, especially the study of nanosized materials [2].
Materials sciences have turned from the traditional "trial and error" research into a quantitative science based on the basic principles.
Due to the unique properties of nanosized materials and broad application prospects, its structure and properties has become the focus of materials science, physics and chemistry, and other cross-disciplinary research [3].
