Introduction In recent year, the environmentally friendly raw materials have been interested and developed rapidly; as follows the growth of environmentally friendly raw materials has higher interest, especially in the application of biodegradable material from renewable sources [1].
The chemical composition from EDXRF report that the biological materials which contain Hydrogen (H), Carbon (C), Nitrogen (N) and Oxygen (O) have the highest concentration, then the other elements, which shown in Table 1 and Fig. 1.

Corrosion Condition The field study on the eroded concrete buildings in JRD and GID showed that white crystal materials appeared on the concrete structures surface and caused surface scaling and lower intensity.
At the second stage, the amount of expansion materials generate great expansion stress, destroy the pore structure and expand the small cracks.
The CM anti-Corrosion Composite Material was developed by Chinese Academy of Sciences，which is mainly used to improve the intensity of concrete.

Composite materials are materials, composed of two or more fundamental materials with different properties, when combined to get a material with different properties than that of individual constituents.
To overcome this problem, a new class of material presented, named as Functionally Graded Materials (FGMs).
