Choose fly ash, admixture(pumping agent, water reducing agent, air-entraining agent), polypropylene fiber and so on from the common concrete materials as testing factors to study the influence law of the performance of raw materials on plastic shrinkage of pumping concrete of ultra-fine sand.
Select the water reducing agent, the pumping agent and the air entraining as experiment factor from commonly used admixture of pumping concrete.
These are much better than affect that water reducing agent single mixed.
Fibers play the role of bridge, which increased the tensile strength of materials to resist plastic cracking depending on the adsorption bond strength between fibers and concrete, and finally decreased cracking extent by reducing fracture speed and crack width depending on its mechanical properties.

It is necessary, however, to take account of factors such as process-related extreme weld cooling rates, dilution levels, possible nitrogen pick-up during welding, etc.
It is known, however, that mechanical properties suffer only if the σ-phase forms as a continuous network in the microstructure, which occurs at sigma levels above about 4 vol. %.
Both mechanical properties and corrosion resistance are then adversely affected.
Selection of base metals containing adequate nitrogen is an important step in maintaining phase balance in the weld HAZ and improving its properties.

Fig. 1 shows that increases in zinc changes the mechanical properties, e.g. strengthen and elongation, of brass[1].
Since 1990, micro-metal forming technology became more and more important [2,3].The main reason for the development of micro-metal forming is that it keeps the forming process costs down, increases production efficiency, and improves mechanical properties and material precision.
The effects of grain size, d/D or d/T to the true strain-stress curves after introducing factors such as grain refining and size-effects will be discussed.
Size-effect is one of the factors that affect micro-metal forming.

Durability provides the ability of the structure to maintain its load-bearing capacity for a certain period of time with simultaneous loading, chemical factors and temperature [7].
Usually, concrete and steel reinforcement largely loses their strength properties when exposed to temperatures above 200-300° C [17].
(4) We rewrite (4) taking into account: , (5) where - function, depending on the ratio of the deformation properties of the material under short-term and long-term load action (material state function).
In order to determine the degree of influence of the external compressive load on the properties of cooled concrete, the prisms were heated and cooled under the action of a load of from the destructive load or in its absence.
As the preheating temperature of the concrete increases, its integrity is violated, cracks appear in its structure, its porosity increases, which is the main factor determining the change in the physical and mechanical characteristics of heavy concrete after the temperature effect.

These nanostructures offer a greater flexibility for the surface functionalization as well as more flexible mechanical properties.
Unlike the widely used CNT, the properties of BNNT are independent of its diameter [5].
Such properties together with the excellent mechanical property and thermal conductivity make BNNT a potential candidate for biosensing applications [7, 8].
Mechanical.
The sensitivity of this biosensing system as a whole depends on a number of factors (e.g., length and diameter of CNT/BNNT, position of beam and target probe).

With the advent of high-power pulsed lasers, laser peening has emerged as a new and very promising technique to improve the resistance properties of materials to fatigue, wear and corrosion.
Introduction The use of high-power laser outputs for the generation of shock waves to improve material properties has been widely investigated since the 1970s [1-3].
With the advent of high-power pulsed lasers, LP has emerged as a new and very promising technique to improve the resistance properties of materials to fatigue, wear and corrosion.
In order to optimize laser peening parameters, it is necessary that the peak pressure P of shock wave induced by laser impacting on the materials surface should larger than the dynamic yield strength D ysσ under purely uniaxial strains in the peened materials, which depend on the mechanical properties.
These factors jointly improve greatly the service life of materials.

As a result, Fe – Gt : N = 1:3 catalyst had the greatest electrochemical properties which is identified by the large area of CV curve.
The Fe, Ni, Co and Mn are 3d-transition metals which can enhance the intrinsic activity by 2-4 times due to a change in morphology, electronic properties, inhibition towards anion adsorption and surface sensitive factors [8].
Furthermore, electrochemical and physical properties were characterized.
