Different kinds of researches reveal that the material intrinsic length is determined by many factors, including materials (e.g. metal, rock, concrete, and clay), material properties (e.g. shear modulus, yield strength, and hardness), material microstructure (e.g.
After natural drying and sieving (diameter<0.075) of clay collected from Tianhe District of Guangzhou the clay is used as matrix materials in this study.
The basic physical properties of materials are shown as Table 1

Conclusion The use of materials with a low coefficient of linear expansion is justified from the standpoint of reducing shell mold stress-strain state, and to increase the shell mold crack resistance and provide for possibility of filling the mold with liquid metal without a backing filler, it is recommended to form the layer adjacent to the outer shell layer using materials with physical properties other than that of the materials of the rest shell mold layers.

In the industrial and civil building, it is served as building materials of projects of the pavement, plaster, and waterproof, and in water conservancy, roads and other specific professional, it is a kind of compression structure carried loads.
However, adding aggregate in the cement mortar is a kind of important approach[1-10], e.g. the Study on Mechanical Properties and Working Performances of Cement Mortar Mixed with Waste Glass Power[1]is one important study achievement, which can improve the mechanical properties of cement mortar recycle waste materials.

Recently, functionally graded materials (FGMs) have gained momentum as a new kind of advanced composite materials.
Unlike classical MMC, FGMs do not suffer from interrupt changes in constituent materials within the FG structural elements.
