Based on cement, fly ash, sand, the desalination sea sand as experimental material.
Modern cement concrete is the most widely used construction materials, is also the most major artificial materials [1].
Due to the sea sand concrete in our country to use history is short, its durability still need to get numerous engineering inspection, with the development of science and technology, precision instrument invention, sea sand concrete durability will get enough guarantee [3].
Sea sand of chloride ions in concrete is caused by corrosion of reinforcement of the main The experimental detail The use of raw materials.

Transparent and highly stressed materials cannot be mixed, because of high demands.
This in-house recycling, known as primary recycling, makes economic sense as it reduces both production waste and utilization of raw materials.
The Shore D hardness test was used to determine the hardness of each of the tested recycled materials.
Recycling of plastic materials.

Transformation characteristics of materials used were analysed using thermomagnetic analysis (TMA) in addition to Thermocalc simulation.
In the transverse direction both filler materials presented mainly tensile residual stress pattern, however in the MCR weld filler the magnitude of stress was lower.

Introduction Concrete is a kind of typical anti-pressure materials.
As a kind of polyphase composite materials, concrete contains many innate flaws and crack tips, which represent the heterogeneous characters at the meso-level.

The theoretical and real chemical compositions of the blank material are presented in Table 1.
All these aspects can also cause and influence other phenomena that occur during small scale deep drawing, like: variation of sheet thickness, nouniform material strength and hence nonuniform material flow in die, material cracking, intensification of springback, wrinkling and earring.

When the small machine tools are made with expensive components and materials it is expected to make savings in a long term run.
Alternative processes like micro electro discharge machining (micro-EDM) can be suitable just for workpieces with 2D symmetry on conductive materials; but leaves heat affected zones and residual tensile stress.
The initial machining tests on Brass and Aluminum materials have shown promising results machined at various speeds from 15,000 rpm to 65,000 rpm.

In the filtering practice two types of filtering materials are used: woven fabrics and non-woven materials, made from various natural and synthetic fibres, as well as various meshes and porous partitions.
The new designs of filters, filtering materials based on synthetic fibres for water purification and disinfection, and of polymer composites and granular contact beds are being developed [3−7].
A flocculant for the clarification of sewage waters from suspended solids at coal-mining industry enterprises and in building materials industry has been synthesized.
