Test Study of Fracture Mechanical Properties of Reactive Powder Concrete with Additives Zhigang Yin 1,2 1.
Fracture mechanical properties of RPC is researched in double-K fracture model and fracture energy release rate G.
What people concern currently is the study on the preparation of high strength and performance concrete as well as its tensile strength, compressive strength and other mechanical properties; while the study about the mechanical parameters, such as fracture mechanics properties (fracture toughness, fracture energy) and the durability affecting the structural use is relatively less, so it is necessary to conduct further research.

The mechanical property parameters of ceramic materials are selected as influencing factors for grindability, the interval sample matrices are established, the interval grey relational coefficient matrices are calculated and the factors weights determined by the eigenvectors.
It is difficult to comprehensive evaluate the ceramic materials grindability using single factor, in fact, there are many interrelated factors that affect the processing of ceramic materials grinding [1-4].
It is convenient and credible to estimate the fluctuation ranges of ceramic materials mechanical properties by testing experiments [6].
Moreover, the weight distinctions are obvious; it is easier to identify the key factors affecting the ceramic grinding.
Conclusions The interval gray principal component analysis method is advanced to evaluate the grindability of ceramic materials; the grindability ranking is based on mechanical properties of the ceramic materials.

Evolution characteristic of soil physical properties is that soil water content, bulk density and porosity made a response to mining subsidence, and soil moisture content variation was much more obvious and affected by seasonal weather.
All the affected indexes of chemical properties did not recover to initial level before mining in one year.
Changes of soil physical and chemical properties in coal mining subsidence land is formed by the ground movement and deformation and cracks and other factors, so the monitoring of soil physical and chemical properties should fully considered the distribution law of surface movement and crack.
Surface non-uniform subsidence, crack sand other factors had led to changes in soil structure in the early days of mining disturbance.
Soil cracks remains the primary factor affecting soil water content, the greater the fracture density, the larger the area of soil water evaporation, the faster the water loss.

When the densities were increased, the mechanical properties also increased.
Utilization of sawdust can be one of the helping factors in adding more types of composite panel product as a new source of material for wood based industry.
It showed that the density was affected by the strength properties of the panel.
The density can affect the strength properties of the composite.
Conclusion From this study, it can be concluded that the homogeneous particleboard composite demonstrated better mechanical properties.

This improvement in structure and properties is attributed to increasing in the cooling rate during squeezing.
Higher cooling rate, especially if coupled with a prompt large undercooling as mentioned above, can cause significant improvements in the structure and mechanical properties of the castings.
Structural changes: by affecting cooling rate of the melt and its undercooling, the applied pressure causes a lot of structural changes.
In consequence, these factors can promote an improvement in mechanical properties [11].
To evaluate mechanical properties tensile tests were carried out on machined specimens having 10 mm diameter and gauge length of 50 mm using a tensile test machine with a crosshead speed of 1 mm/min, Fig. 1.

There are reasons for coupling investigations on the residual mechanical properties to fire resistance data, aiming at a more complete knowledge of the behavior of a masonry member during and after fire exposure.
Generally, the maximum temperature of exposure is the main factor that affects the residual mechanical properties of concretes and masonry materials (aside from the parameters that are peculiar to the material); secondly, the duration of exposure, the heating rate and the cooling regime [23] are of relevance.
The decay of a generic mechanical property Χ after fire exposure, i.e. the ratio Χres/Χ = kq between the decayed and the original property, could be expressed as a function of the maximum exposure temperature q, provided that the other relevant factors (heating rate, duration at maximum temperature and cooling regime) stay unvaried.
This numerical research proposes factors of original properties < 1 (listed in Table 3) that can be of reference for correlation between fire endurance and residual load capacity; in fact, such factors express the mechanical decay in post-fire condition in the worst case, i.e. after the wall has exceeded its prescribed fire resistance limit.

The metastable β Ti-6Al-4V alloy has been used clinically as a permanent implant material owing to its suitable mechanical properties and biocompatibility.
There are some factors in considering the selection of alloying elements such as the fabrication method and the resulting mechanical properties.
The alloys produced from the casting method require post-treatment to improve its mechanical properties and to minimize casting defects [1,4,5].

The involved manufacturing processes which including thermal-mechanical processes, material deformation, machining or any of operations that change the shape or properties of metals can lead to the origin of residual stresses in components.
Therefore, the engineering properties of structural components, such as fatigue, distortions and dimensional stabilities will all be considerably influenced by residual stresses [10].
The degree of distortions depended on the magnitude and geometric extension of the residual stresses, as well as many other factors, such as heat-transfer coefficients between parts and quenchants, uniformity of the quench, heat flow within the steel, transformations (as a function of chemistry, position, time and temperature cooling rates), carbon concentration gradients in carburized steels, temperature-dependent mechanical properties and plastic flow characteristics of mixtures of austenite and its decomposition products[14].
Also, to decrease the cooling gradients between different parts, such as, proper heat treatment approaches with excellent microstructural properties, can further improve the dimension stabilities.
