In 1997, Academician Wu Zhongwei, a pioneer and founder of the concrete science and technology, first proposed the notion that green high performance concrete be the direction that the concrete takes.
In order to reduce the dosage of cement and concrete, the development of green high performance concrete mixed up with industrial waste slags makes concrete which is the biggest artificial materials become truly sustainable material.

Introduction
Performed mechanical properties in combination with low density of work piece material are the
key features for lightweight constructions in automotive and aerospace applications.
It is obvious that manufacturing process in the fabrication of metal matrix composite materials will influence in some extent the performance of these materials.
Rheological Investigations Rheology is defined as the science of deformation and flow of matter.

For example, CF have been found to exhibit good electrical conductivity, super-high strength and elastic modulus, which exceed those of many conventional materials[1,2].
Fig.1 SEM micrograph of original material (a) G powder, (b) Cu powder and (c) CF Results and discussion Comparing with Fig.1(a,b) and Fig.2, through the ball mill, we can find that not only the branch crystal struture of copper and flake graphite were not destroyed, but also the bad wettability of copper and carbon were improved.
The value can make Table 1: Table.1 The actual density and relative density of 4%C/Cu, 4%C/Cu-CF Actual density [g/cm3] Relative density [%] 4%C/Cu 6.76 84 4%C/Cu-CF 7.35 95 Through the comparison of the different sample density values,we can find that CF is influential C/Cu composite materials’ density.
Joining Cu-coated CF is not blocking the spread of metal atoms, promoting it and reducing the porosity of materials.

Accordingly, it concentrates on cases where it is possible to
define specific domains of the inert materials.
These materials can be classified into four main groups, namely carbonaceous materials, oxides, metals and polymers.
