Volume stability of cement-based materials is the ability to resist mortar deformation under the actions of physics and chemistry, which also is the important aspect of cement-based materials’ durability.
The poor volume stability of cement-based materials directly leads to the emergency of cracks.

And materials data integration and control are one of core competences concerning with the development of mass data application in manufacturing enterprises.
In this paper, a context-aware materials data integration meta model is presented which is incorporating an advanced materials demand mapping and decomposition mechanism to support fine-grained materials data in the right time for the provision of materials services, based on the analysis of the application context involving the key points and relationships in their manufacturing processes.
Materials Data Context-aware Model Proper Data modeling is an essential task for providing an efficient and effective representation of the phenomena of interest.
Actually, this is the mechanism for obtaining first-order context information from raw materials data.

Grain refinement had many advantages: the negative effects of grain boundary material was reduced to a minimum; materials were not easy to cause transcrystalline fracture; improving fracture toughness and wear resistance of material, making materials have superplastic behavior in high temperature.
Thus the property of materials will be the excellent.

Typical LCS design [11] Clog material composition A number of studies have been performed to investigate clog material composition of landfill LCSs (Table 1).
The anaerobic bacteria in the leachate easily remove volatile fatty acids (VFAs) from the leachate , colonize the surfaces of leachate collection systems materials and form a thick biofilm [2, 16-17, 20, 22-26].
The use of a filter–separator between the gravel and waste material can help reduce the amount and rate of clogging in the underlying gravel drainage material [37].

According to the theories of gas seepage and deformation of coal or rock seams, taking consideration of the heterogeneity property of coal or rock materials in mechanics of materials as well as non-linear permeability characteristic of coal or rock materials in the process of deformation and fracture, SPH algorithm of LS-DYNA software is used to numerically simulate the coal-gas outburst induced by development in coal seams.
The nonlinear nature of the mutation of outburst induced by gradual destruction of the coal or rock materials under the influence of developing operations is revealed, including the evolution of the stress field in the rupture process of the coal or rock material.

The third is the standard for specific purpose that is formulated for the materials with specific purposes.[3] They Introduced the Risk Assessment to Evaluate the Safety of New Materials In addition to considering the structure and properties of the packaging materials themselves, they make a migration simulation test with their contact products to evaluate the effect of packaging materials on agricultural products and foods safety.
The migration test is used to evaluate the content level of food residue from packaging materials and is the required test of new packaging materials.
Secondly, strengthen the awareness of environmental protection, increase the investment of science and technology and develop non-toxic, harmless and biodegradable green packaging materials to insure the process from raw material purchase to product manufacturing to accord with the environmental protection requirements of import countries.

Si/C composites were prepared by spray dying and carbonization process using silica powder, artificial graphite and glucose as raw materials.
Powder X-ray diffraction (Philips X’pert MPD, 20KV, 40mA, CuKα) was used to identify the phase composition of synthesized materials.

Cordierite-mullite multiphase ceramics material has been produced from various starting materials [6].
There are many methods which could improve properties of ceramics materials, the most effective way is the use of additives.
These apparent porosities became some fracture sources which could severely decrease the flexural strength of multiphase ceramics materials.
According to the theory of thermal shock damage, the critical thermal shock resistance of materials was directly proportional to the materials' strength, but the ability of crack propagation was inversely proportional to the materials' strength.
