The knowledge about physical and mechanical properties of the bricks is quite incomplete, especially the earthquake resistant behavior, which limit their more widespread application [3-5].A four storey masonry building model with 1:3 scales is built.
Compared with the conventional recycled concrete brick, the composition of the construction waste recycled bricks is more complex, so its’ mechanical properties under load will change greatly.
The physical and mechanical properties of the bricks with curing age of 28 days can be determined by experiments.
At the beginning and the end of the tests, the white noise was applied to identify dynamic properties of the model.
Mechanical and frost-resistance properties of rural area building waste hollow bricks.

As a result of the experimental data processing, the equations reflecting the influence of the varied factors on the studied indicators of the low-clinked binder properties have been obtained.
Taking into account the importance of the regression coefficients it is possible to draw a conclusion that, first of all mutual influence of factors x1 and x2 has affected the size R28.
As the overdose of superplasticizer C-3 or the increasing of the water-binder first of all affects the durability of solutions and concrete, as the mutual influence of the specified factors on the 28th day has decreased considerably.

Combining micromechanical testing and chemical analyses will help the study of basic wood properties.
Results and Analysis  The tensile strength of the fir, pine tracheid material  At first, Zero-span tension technology used to study the tensile strength of paper fibers, and later for the mechanical properties of wood tracheids.
The most serious problem of application of the technology to test the mechanical properties of wood tracheid was that whether the measured intensity value completely representative of the mechanical strength of the tracheid.
It is a new measurement of wood micro-mechanical properties.
Thereby affecting the degree of crystallinity of wood, in the end it makes the reduction of crystallinity of wood, wood tracheid longitudinal tensile strength decreased.

The components of iron ore concentrate and magnesia binder, having improved sorption properties, significantly accelerates the formation of such a structure.
It is known that the materials on magnesia binders have enhanced protective properties from electromagnetic radiation.
The radiation-protective properties of materials were measured by linear and mass attenuation factors of γ-radiation using a DKS-96 dosimeter-radiometer.
Further, the effect of LC and its heat treatment products at 800 ° C (LC800) on the properties of the magnesia binder was investigated.

Most existing researches are about the basic mechanical properties of the concrete after freeze-thaw cycles.
Zhao[13] studied mechanical behaviors of concrete beams reinforced by GFRP after freeze-thaw cycles.
Though ultimate load has no obvious decrease between 0 to 75 freeze-thaw cycles, downward faster after 75 freeze-thaw cycles. 2.4 Effection of stirrup ratio on cracking load, ultimate load Stirrup ratio is one of the main factors affecting the performance of concrete shear behavior, Effection curves of stirrup ratio on cracking load, ultimate load are shown in Figures 6 and 7.
The increasing of freeze-thaw cycles result in faster development of strain stirrups, and the final value decreases; (3) Concrete beams cracking load and ultimate load decreased with the increasing of freeze-thaw cycles, stirrup spacing’s increasing, and the freeze-thaw cycles considered being the main factors.

Summarize the previous research results, the mechanical properties of nano-rod influenced by various factors.

Necessity Surface roughness is one of the most important factors for evaluating work piece quality during the finishing process because the quality of surface affects the functional characteristics of the work piece such as fatigue and fracture resistance and surface friction.
Depending upon these three factors the corresponding responses measured are surface damage (%D), surface roughness (Ra) and tangential force(TF). 5.
The other parameters which are affecting the experimental results are assumed to be constant. 9.
But the grit size of the wheel is not affecting in the analysis of the surface roughness (Ra).
For the response tangential force (TF), the depth of cut, feed rate and grit size are the significant factors.
