Four variables, water to cementitious material ratio (W/CM), sand ratio, cement replacement ratio, and the average particle size of clay-brick-powder were determined to analyze the affected factors on the properties of the concrete.
(3) W/CM is the most important factors affecting concrete strength.
Normally, the concrete properties reduced as the W/CM increased.

Mechanical Properties of Concrete with Recycled Clay-Brick-Powder.

One of the factors that greatly affects the homogeneity of the mixture is the surface treatment of the guides that are designed to transport the granulate and it is important to take care of those lines.
Major factors include productivity, reliability, service life, labour cost, repairs, additional mechanisms and maintenance [1].
Is defined by ISO 9000: 2000 as a complex property of an object (Fig. 1): Reliability - is defined by the standard as a generic term used to describe the ability of an object to work and the factors that affect it.

They serve to modify the properties of plastics.

On the other hand, however, on the nanometer scale, the electrical properties of materials are affected not only by the structure and composition of these materials, but also by the mechanical factors of stress and strain due to lattice vibrations.
Thus, it is a great needing to research the electrical properties of materials on nanometer scale.
As the result, the M-AFM can be used to measure the electrical properties of materials with a high operating speed.
Such difference can be corrected by the calibration process with a zero setting, therefore it will not affect the evaluation of electrical properties of materials.

A study was carried out to evaluate how the Friction Stir Spot Welding (FSSW) process parameters affect the temperature distribution in the welding region, the welding forces and the mechanical properties of the joints.
Aim of these experiments was to evaluate how the welding process parameters affect the thermal distribution in the welding region, the welding forces and the mechanical properties of the joints.
The mechanical properties of the joints were evaluated by means of shear tests.
A general good repeatability was found in all cases and all the considered factors (S, F and Z) have an influence on the mechanical properties of the joints in terms of shear resistance.

However, unmodified blends are thermodynamically incompatible that negatively affects properties of the material [2].
Results and discussion Mechanical properties.
Apart from incompatibility this could be additional factor determining low mechanical properties of PP/NBR blends.
Mechanical properties of the investigated blends are especially affected at elastomer contents above 50 wt. %, especially for PP/NBR blends.

Many researchers, therefore, discussed the mechanical properties of the composite plating [2-7].
Hojo et al. [8] pointed out that the cleaning process of SiC particles, in which the particles were washed in an acidic solution to remove impurities, affected the particle dispersion into a nickel matrix and thus the mechanical properties.
Their friction properties were also discussed.
The friction and wear properties were evaluated by a ball-on-plate type reciprocating friction tester.

Evaluation of Mechanical Properties for Selected Dental Composite Resin Polymerized by Light Curing Technology at Different Thickness Fatin M.
Introduction A properties of composites materials containing resin are often re-evaluated because they may be affected by several factors, such as hardness and an intrinsic strength of a material, depending on a shade of the composite resin, the processing time, the phototherapy unit, the radiation, the spectrum of light emitted [1, 2].
Various studies have precise the effect of light emitting diode therapy on the properties of photovoltaic compounds.
Compressive strength was used in the mechanical and restorative properties evaluation test.

Therefore, preheating can influence the properties and fracture behavior of the joint by affecting the IMCs thickness and wetting ability of the aluminum alloy layer on the steel surface.
Meanwhile, the mechanical properties of aluminum alloy 6061 and Mild Steel Q235 were shown in Table 1 and Table 2.
Table 1 Mechanical Properties of Aluminium Alloy 6061.
Because the melting point of aluminum is lower than the filler metals used in this research, during joining of aluminum to mild steel, several factors can affect the porosity formation, such as solubility of the gas in the molten metal, temperature, viscosity of the molten pool and solidification time of the molten pool.
