Introduction Reinforced concrete (RC) is a kind of composite material which has become the indispensable choice to civil engineering.
Materials and mix proportions In order to reduce the discreteness of concrete, commercial concrete of grade 30 were applied to cast the specimen, the cementitious materials used for this investigation were Chinese standard (GB175-99) #42.5 Portland cement [7].

According to the National Science and Technology Commission, State Planning Commission, State Economic and Trade Commission statistics, China is one of the countries which have the most serious geological disaster hazards in the world.
It can reflect the present value of the affected property or material.
General the loss of fixed assets includes loss of buildings, means of transport, machinery and equipment; special loss of fixed assets such as roads, bridges, tunnels, culverts, hydraulic structures losses ;the loss of materialized current assets includes raw materials, fuel, auxiliary fuel, semi-finished products, finished products, goods and physicochemical current assets losses.
Other loss of material wealth includes agricultural products, fruit products, aquatic products and livestock products losses.

Forward New material data for selected alloys will be introduced to the models.
Finally new material data for new alloys will be introduced to the model to establish their formability.

Influence of Rapid Solidification on the Microstructure and Mechanical Properties of NiAl-Based Near Eutectic Alloys Jianting Guoa, Hutian Lib, Kaiwen Huaic, Gusong Lia Superalloys Division, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China a jtguo@imr.ac.cn, b htli@imr.ac.cn, ckwhuai@imr.ac.cn Keywords: rapid solidification; NiAl-based eutectic alloys; compressive deformation Abstract.
The existence of extensive dislocation network will strengthen the material by providing obstacles for dislocation motion, which could provide a strengthening of the order of [11] f=G∆b/2πb
However, operation of similar sources throughout the material probably leads to the high dislocation density observed throughout the NiAl phase in the samples.

The resulting deformation of the material, which is, bending toward the laser beam, is permanent.
The assumptions made for the numerical modeling are as follows: The workpiece materials are isotropic; the laser works in a continuous wave mode; no melting occurs in the laser forming process and no external forces are applied to sheet metal.

To evaluate the compaction process of powders Fe-20Cu (wt%) and Fe-20Cu-4 diamond (wt%), it was used the Balshin[4] and Rong-De's equations [5], once it is necessary to choose the ideal zone of compaction pressure for a minimum of porosity in the system - maximum of densification, mainly for the diamond composite, because it is mandatory the determination of the ideal range of compaction for this class of material, because the use of excessive pressures causes the premature wear of the compacting matrix and general rigid parts, due to the high hardness of the diamond crystals - that causes excessive wear and in it.
In addition, it is a original paper, in the point of the view of the preparation of diamond composites of metallic matrix, without scientific data about this class of materials preparation.

At the same time, aspen wood by-products can serve as a good raw material for obtaining new value-added products.
A study of the effect of the acid concentration in the low temperature hydrolysis (1 h at a hydromodulus of 1/20) on the amount of the released extraneous materials (the water-soluble products formed as a result of wood hydrolysis) shows (Table 1) that, with growing HCl concentration, their amount in water increases.
The ammoxidation of lignocellulosic materials can be one of the promising ways of their purposeful modification due to the efficiency and relatively high yield of the end product, the simplicity of the implementation of the modification process, the low content of by-products and the use of water as a reaction medium.

Fig. 3 Polishing covering area Experimental Configuration Material of Specimen.
Based on Table 5, Abrasive material, concentration, numbers of nozzles and step over have been pooled as error to meet the level of confidence.
According to Fang et al [17, 18] and Tsai et al [19] investigations, the material removal rate depends greatly on angular rotational speed and dwelling time of nozzle scanning.
It is evident that uniform material removal over a large area with a small polishing spot exhibits enormous challenge which requires extensive scanning of micro polishing nozzles constantly over the specimen.
