These researches have very important guiding significance for grouting construction and development of grouting materials.
On this basis, the variation of slurry affinity with time was discussed, and the mathematical model of viscosity and affinity of CW epoxy resin slurry with time was established. 2 Materials and Methods 2.1 Test materials and preparation methods CW epoxy resin grouting material, containing two components A and B (mass ratio A:B=5:1, A:B=6:1), produced by Yangtze Academy of Sciences.

On the other hand there are several properties which are not easily reproducible in the most of the materials characterization, and particularly in the quantification of the material.
In this paper a concept of traceability is introduced for the measurements of materials properties.
Particularly important is the development of reference materials, which are described below.
By the agreement of ISO/REMCO, they are stated as folloows: • Reference Materials(RMs): A material or susbstance, one or more properties of which are sufficiently well established to be used for calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials.

MgAl2O4 spinel b) a) Fig. 2 Composite materials based on EN AC-44200 Al alloy, (a) ultimate tensile strength of unreinforced aluminum alloy (0%) and of composite materials reinforced with 10 and 20 vol.% of Saffil fibers at 20-300oC, (b) Fracture of composite materials with cracked fibers partly covered by MgAl2O4 spinels –scale bar 5 mm Normally composite materials applied in the production of car engine parts are subjected to several thermal cycles.
Thus, coefficients for composite materials at higher temperatures of 300-400 oC were significantly smaller and decreases from 22 to 13x1/106 deg correspondingly for unreinforced Al alloy and composite materials with 20% of fibers.

The life cycle cost (LCC) of the green building materials is the remarkable difference and also advantages in contrast to the normal building materials.
Setting up green building materials LCC evaluation system is the application of LCC industrialization promotion in the green building materials industry.

On the Issue of Predicting the Strength Characteristics of Dispersed-Hardened Polymeric Composite Materials at the Design Stage of Engineering Products Notin Ilia1, a 1Bauman Moscow State Technical University (BMSTU, 105005, Moscow, Russian Federation, 2nd Baumanskaya St., Bldg. 5, Block 1 ainotin@ya.ru Keywords: particulate filled polymeric composite materials, strength characteristics, composite materials, mechanical engineering, machine building technology Abstract.
The use of new promising materials allows achieving higher operational and technological characteristics of the final product.
Thus, a significant reduction in time and material costs at the stage of preparation of production of products from dispersed-reinforced polymeric composite materials is possible.

Only the numerical method can be applied to calculate the sound transmission loss (STL), however, in the cavity of the air cleaner there are some filter materials whose acoustic property is hard to describe precisely even if using the numerical method.
In the experimental duct system，a filter material was mounted between two testing pipes.

Considering the good infiltration capacity of rockfill materials in general, the shearing rate is set at 0.4mm/min.
This may be attributable to the high strength of grains in primary and secondary rockfill materials.
