Introduction
Requirements regarding reduction of cars’ fuel consumption play a key role in automotive as they make cars lighter by application of more and more resistible materials.
Application of this kind of materials considerably reduces construction mass thanks to high durability.

Abstract.
In particular, the time-and stress-dependent material properties of the PCC have been explored only partially.
Materials The research were made with a low strength class Portland cement CEM I 32.5 R, to clearly point out the influence of the polymer modification.
Furthermore, crumb rubber as substitute materials with very little resistance to deformation were used.

Introduction
The dehydration technology and equipments for existing fine grain materials cannot meet the dehydration requirements of coal slurry in the respects of product moisture, processing capacity, working system, capital investment, operating expenses and reliability [1,2].Thus, to research new type continuous, efficient and highly reliable dehydration technologies and equipments and strengthen the dehydration for fine grain materials is significant for the respects, such as to promote the technology of clean coal, improve and enhance the productive technology level of coal preparation plant, increase the enterprise’s economic benefits, enhance the utilization rate of resources and environmental protection, etc[3].
So in practical operation, with the available conditions, it shall try to increase the filter concentration, increase the filtration pressure, increase the content of coarse grain materials to get lower filtration product moisture.From the numerical expression of actual influence factor, we can see that : the filter cake moisture increases as the feed concentration increasing, but the influence is not big; the filtration pressure is the most largest influence factor for filter cake moisture, the much higher of the pressure, the much lower of the filter cake moisture, and conversely, the filter cake moisture much higher.
As the fine grain content in feeding materials increasing, the filter cake moisture rises, filtration period and filtrate concentration larger, and the treatment capacity lowers. 2)Perform design, result analysis and optimization for series of test of positive pressure filtration dehydration effect for feed concentration, filtration period and filtration pressure by Design-Exper, result of which shows: the filter cake moisture, filtrate concentration and dry coal slime treatment capacity has notable linear relations with the three operation parameters. 3)The mathematical models for relations among filter cake moisture, filtrate concentration and dry coal slime treatment capacity and the three operation parameters are respectively expressed as: Filter cake moisture=33.662622-0.024704×A- 0.15708×B+13.69179×C Filtrate concentration=-0.60444+1.8311e-3×A+8.517e -3×B+2.28435×C Sqrt(dry coal slime treatment capacity)=-16.60950+0.082385×A-0.016163×B-0.80814×C 4)Through the research on

Selective laser melting process Introduction Additive manufacturing represents various processes for making a three-dimensional object of almost any shape from a 3D model or other digital data source primarily through additive processes in which successive layers of material are laid down under computer control [1].
Micro hardness mark left on SLM part Micro indentation hardness test, is a hardness test using a calibrated machine to force a diamond indenter of specific geometry into the surface of the material being evaluated (Fig. 9.), in which the test forces are 9.807x10-3 to 9.807 N (1 to 1000 gf) and the indentation diagonal, or diagonals are measured with a light microscope after load removal.
