Properties of a Composite Cement Binder Using Fuel Ashes V.V.
We used different types of fuel ashes as active mineral additives with the following physical-mechanical and chemical properties (Table 1).
Analysis of the strength data shows that each additive affects the strength of the binder to a different extent, depending on its properties.
We can recommend these materials as additives only in the case when it is acceptable to use a binder with low physical and mechanical properties.

The interlaminar shear stress widely exists in the laminated structures of various composite materials actually [3], and its influence on the mechanical properties of composite materials is worthy of further discussion [4].
In the early stage of interlaminar shear stress research, many scholars explored and analyzed the factors influencing interlaminar shear stress through experiments.
Pagano and Pipes think that the lamination sequence along the thickness direction at a specific angle will affect the value of interlaminar shear stress, even the positive and negative [5], which is of great significance for analysis of the properties of laminates.
In order to analyze the physical factors causing the interlaminar shear stress of composite laminated structures, some scholars have studied the effects of elastic modulus, Poisson's ratio and shear modulus on the interlaminar shear stress [6].

The single factor test method was used to study the influence of pulse energy, pulse width and repetition frequency on the quality of micro holes.
The results revealed that pulse energy is one of the biggest influence factors, large pulse energy can lead to small hole taper within a certain range, and short pulse width can reduce orifice debris and splash.
Therefore, according to the requirements of the pore processing and the thickness of the material properties, pulse width should be choosed carefully. 2.3 Effects of repetition frequency Laser pulse repetition frequency is the number of pulse laser in unit time, As shown in type (3), between repetition frequency and average power has the following relationship: P average=E×F (3) Type：E is pulse energy; P average is average power；F is repetition frequency.
This is mainly because the pulse energy and pulse width are the main factors.
(2) Among the three process parameters, pulse energy is the most important influence factor of holes quality

The mechanical properties of solidified sludge block were evaluated by compressive strength, chemical oxygen demand (COD) and heavy metals concentration in the leachate from the solidified block were tested as well.
The hydration reaction Ca(OH)2, ettringite and calcium silicate hydrate and other hard water material, they cause the treated products have good mechanical properties [9].

Polysulfone (PSf) membrane relatively has great mechanical properties, resistance to extreme pH conditions as well as thermally stable.
However, to date, the previous work on water as non-solvent additives did not provide definitive information on membrane mechanical properties.
Porosity and tensile properties.
There are many factors that influenced the formation of membrane structure prepared via phase inversion method.
In general, membrane porosity has a direct relationship to the flux permeation, rejection and also mechanical properties of membrane, and can be considered as a key specification factors for the membrane performance.

Among modern composite materials, particularly, discontinuous reinforced materials, such as aluminium matrix composites reinforced by SiC particles, have become practical engineering materials due to their superior performance like high mechanical properties, wear resistance, low coefficient of thermal expansion [1].
Though many factors affect the grinding process, the machining parameters such as wheel velocity (Vw), workpiece velocity (Vc), feed rate (f) and depth of cut (ap) are the important parameters.
The ANOVA analysis in Table 3 and percentage contributions for each term affecting grey relational grade (Figure 3), indicate that the all four process parameters i.e wheel velocity, workpiece velocity, feed rate and depth of cut are the important parameters affecting the multiple performance characteristics.
