Introduction The wear of Agricultural machinery by plant material is the chief reason which affect the mechanical endurance, such as feed processing machinery, grain grinding machinery[1].
In the production practice of ring die pellet mill production and grass particles, the shape, the physical and mechanical properties of the alfalfa are different with compound feeds.
The study on the abrasive wear properties of metals using alfalfa meal is necessary.
Testing design The chemical composition and mechanical properties of 45 steel and HT200 iron, which size is 65mm×30mm×10mm without any heat treatment are showed in table 1 and table 2.
This study selected the speed, abrasive size and load as the main factor to test regardless of interaction.

Accordingly, the thumb rule is to avoid, or at least to minimize, the critical factors impeding the primary healing, i.e. the associated mechanical, thermal and vascular damage generated by bone drilling [1-4].
The reason of choosing bovine femoral bone for this in vitro study was based on thermal isotropic properties of bovine and human bones, and on homogeneity and constant thickness of bovine cortical bone as well [17].
Obviously in implant failure may be involved a combination of various factors and is rather difficult to find out the real etiology.
The large tool bit diameter is adversely affecting the bone tissue as is increasing the temperature during drilling process [19].

This will help to understand the effect of crystallization conditions on the structure and mechanical properties of triblock TPUs.
All these factors limits direct interpretation of IR-spectra in terms of hydrogen bonding and phase separation.
The numbers correspond to the sample numbers in Table 1 The degree of crystallinity and the structure of the crystal phase affect the mechanical properties of adaptive materials.
The most critical factors are degree of crystallinity and interface between soft and rigid block formed by corresponding polyol and diisocyanate.

Anthropogenic Carbon Aerosol Induced Carbonation in Reinforced Concrete: Deterioration Effects on Mechanical Properties O.E.
Experimental tests were carried out to study the effect of carbonation caused by the emission of black carbon soot on mechanical properties and durability of reinforced concrete.
Moreover, there are some environmental and climatic factors such as carbon dioxide (CO2), black carbon soot, humidity, and temperature that affect carbonation and chloride ingress in concrete[10].
Conclusion The study aimed at investigating the anthropogenic carbon aerosol induced carbonation in reinforced concrete, with a significant focus on the deterioration effects on mechanical properties.

The main factors affecting concrete durability Subterranean environments structure concrete corrosion of reinforcement corrosion, mainly by erosion, dissolution and alkali salt - aggregate reaction and other factors.
We analyze the underground water, environment and resulting in the concrete structure rebar corrosion damage is the main factors of chloride ion penetration and prompted reinforced produce electrochemical corrosion, cause the cracking of concrete expansive, seriously affecting structures using life.
So we think the main factors affecting concrete durability is concrete chloride permeability velocity and chloride ions diffusion coefficient.
Pile high-performance concrete performance study Experiment with raw materials and its physical and chemical properties.
Concrete physical and mechanical properties test results, anti-chloride ion permeability and chloride ions diffusion coefficient test results as shown in chart 9.

The result shows that the coating has good coating effect, excellent mechanical and chemical performance which can meet the camouflage requirements of changing seasons.
TiO2 is white and very stable and the difference of additive amount will not affect its photochromic properties; CuCl2·2H2O, 0.85g; CoCl2·6H2O, 0.6g; MgCl2·6H2O, 2g.
Properties testing Spray and paint the prepared acrylic acid modified novolac epoxy as an important component of a painting whose color changed by temperature on tinplate in accordance with GB1727-79[5].
The physical and mechanical performance of film was tested one week after been dried at room temperature.

Temperature changes (hot and cold), the intensity of solar radiation, atmospheric gases, humidity, rainfall, and wind are all factors that create stress in structures [6].
Based on the experimental protocol, it is proved that factors affecting mortar carbonation are (i) pore system of hardened mortar, which is influenced by the w/c ratio, binder type, and hydration level; (ii) relative humidity; and (iii) the CO2 concentration.
