Without any treatment, most of them were transported to the outskirts to pile up in the open air or landfill, and that would need a considerable amount of construction investment with land and other factors.
Currently, more and more studies have been paid to the properties of recycled concrete aggregate at home and abroad[5,6,7], but the research on recycled brick concrete was still less.

The mechanical behaviours of SiCp_A356 composite at room and elevated temperature were investigated.
This is because of their superior properties such as enhanced specific strength and stiffness, high thermal conductivity, low weight, high heat capacity and high-temperature resistance[3,5].

The thermal conductivity of nanofluids depends on several factors such as temperature, concentration and temperature.
These parameters have the most significant effect on thermal conductivity compared with other factors.
By applying nanotechnology it is possible to improve the strength of material, their thermal conductivity and other thermophysical properties [3,4].
Among the several factors, temperature, concentration and size of nano particles are among the most important ones.
Thermal conductivity and rheological properties of graphite/oil nanofluids.

PLA has broadened its application range due to its good mechanical properties relative to petroleum-based commodity plastics, relatively accessible cost, biodegradability, and biocompatibility [2].
We investigated the factors that increase molecular weights through the control of experimental variables and focused on the synthesis of HMW PLLA.
However, considering the difference in molecular weight, it is evident that the end-group content of the growing chain in the amorphous region during SSP is a key factor affecting molecular weight increase.
The amount of water present in the monomer is the most critical factor affecting the increase of molecular weight since it increases the reverse reaction rate during the polymerization of PLA.

Introduction Molded parts precision, performance and efficiency are the three main factors that slows down the development of RPM, in which the four main factors affecting accuracy of FDM parts can be summarized as follows: ① Errors caused by prototyping system, referring to the localization accuracy and repeatability of localization accuracy of nozzle motion; ② Principle errors caused during the triangulation and slicing process; ③ Errors caused by nozzle with a certain diameter; ④ Errors caused by material shrinkage.
Second, with temperature increasing, it gradually changes to high-elastic state and finally to melted state where it shows rheological property, very important property for FDM process.
Extrusion temperature determines the bonding properties of materials, accumulation property, filament material liquidility and extruded filament width.
However, not a fixed value is the width of extrusion filament, subject to influence of many factors such as nozzle diameter, layer thickness, extrusion speed, scanning speed, extrusion temperature, envelope temperature, coefficient of adhesion, shrinkage rate, and so on.
In addition, there also exist other factors affecting parts accuracy such as principle error, error caused by numerical control system and error caused by material shrinkage etc..

The different control and uncontrollable factors are evaluated by placing it into an orthogonal array form.

And further, independent sealing pores, high mechanical strength of pore wall, pore structure approximate to sphere and pore diameter with similar and small size were all favorable factors for higher strength of foam concrete.
This test will be in accordance with the above these problems, through the test research to reduce exterior insulation with foam concrete plate density at the same time, improve the compressive mechanical properties such as tensile strength of the effective methods, and on this basis to discuss the influence of the bubble pore structure, for this new type of inorganic heat preservation material, the popularization and application of the lay the foundation.
Because chemical foaming has huge advantage in strength , water absorption properties and low density, the method of chemical foaming is selected in test andf foaming agent is hydrogen peroxide.

The solder joint geometry plays an important role among the factors that affect solder joint fatigue performance [1].
Considering solder joints shape parameters including height, diameter, solder outline and contact angle, it is not comprehensive to consider separately the height as the single factor affecting the ability of solder joints to resist thermal fatigue.
But the mechanical properties of LF solder joints during the thermal cycling test are not as well-studied as SP solders.
The model includes molding compound (MC), a chip, a BT substrate, top Cu pads, bottom Cu pads, solder joints and PCB which all have their unique material properties as shown in Table 2 [6, 7].
The material properties of the eutectic 63Sn/37Pb solder, the hypoeutectic 96.5Sn/3.0Ag/0.5Cu and the PCB were all dependent with temperature.

Introduction With the development of modern science and technology, there are more and more high demands on the material properties in each field.
Machined Surface Quality Machined surface quality contains surface roughness and surface defects, which affects the mechanical and physical properties of the parts. 
Among the influencing factors of surface roughness, the influencing of the cutting feed is largest, then the cutting speed and the particle content[7].
Cutting parameters are the main factors that affect the tool wear and the effect of the cutting speed is largest.
