The constructional quality judicatory authentication involves the significant interests between both parties of prosecution and the defense and the conflicts exist inevitably in the process of court hearing and evidencing over the verification of the information and documents, therefore the persons involving the judicatory authentication shall insist in the principles of science, rigors and objectiveness and fairness in their operation.
The hardening and cooling contractions of the materials of beams concrete are constrained by concrete framework columns and the constrained pulling stress are caused on the beams’ vertical cross section, while another pulling stress are on the beam bottom due to load action.

It well known that almost of the important technologically materials are not available in the nanocrystal way.
Moreover, the powders and pressing materials are easier to be obtained with low cost.
This confirms hypothesis that the microdeformations is caused by release of organic materials in the structure.

The crystallisation mechanism of glass-ceramic materials from a CMAS group Al0.37B0.34Fe0.01Mg0.02Zn0.29Ca0.05Si0.78O3 was tested under non-isothermal conditions by the DTA method.
By proper selection of chemical composition to obtain specified crystalline phases it was possible to deign materials for specific applications, e.g. body stubs in microelectronics, biomaterials, composite fillers, bonding materials, high-duty and hard materials resistant to wear [1,2].
Glass-ceramic materials from a CMAS group, with the main phase in the form of diopside, respecting their high wear resistance were also used to reinforce among others alumina composites, and also they constituted an important group of materials such as binders for porous abrasive composites [6].

Textile fiber material recycling economic cost, mainly through analysis the cost of new textile fiber materials prices and the price of recycled fiber, of which the price of recycled fiber is the recovery of the prices of textile fibers combined with the recycling processing costs.
Waste textile fibers materials recycled including two major parts, one is waste fiber turn into recycled fiber, and the other is the use of recycled fiber process [5].
If waste fiber materials return to fiber state, they must be removed through finishing agent, decolorizing, and opening into a single fiber processing technology.

The reason for this change may be that the organic acid generated at the earlier stage of the compost has been gradually decomposed or compound into humus with other materials with the proceeding of the compost, at the same time, the release and accumulation of NH3 cause the pH of materials to increase and stabilize at the end.
