Improved strength properties were obtained by using hydrothermal curing conditions and super-plasticizer addition.
The properties of the rock chips were tested according to ASTM C136 and the results are presented in Table 2 and Table 3.
Under the three curing methods, the main influencing factors of the total shrinkage were relative to hydration, the drying shrinkage of hardened cement pastes and moisture loss or migration.
The three factors corporately played roles on the shrinkage of the blocks under the curing method B.
Effect of silica fume and expanded perlite addition on the technical properties of the fly ash–lime–gypsum mixture [J].

For a given package, the misalignment of the fiber tip is determined by three key factors, namely the laser pulse energy, the welding sequence and the welding position [1,2].
PWS affects not only the coupling efficiency of the transceiver module [3,4], but also the bonding reliability [5] and the fiber shift in the fiber ferrule [6,7].
The model was constructed using eight-node hexahedral 3-D thermal-mechanical elements.
In performing the simulations, the material properties of the package components were assigned the temperature-dependent values.
A thermal-mechanical finite element model has been used to identify the welding sequence which minimizes the PWS within the package following the initial welding process.

In order to popularize the development and application of super high strength concrete prestressed pipe pile in China, the research on its mechanical properties is especially important and urgent.
Material Properties 2.1 Constitutive relation of concrete The non-linear analysis of reinforced concrete is carried out in ABAQUS.
Finite Element Calculation and Finite Element Calculation of Horizontal Bearing Capacity of Prestressed Pipe Pile Considering Different Factors The effects of different vertical load and hoop ratio on the horizontal bearing capacity of prestressed high strength concrete pipe pile under vertical load are analyzed.
The energy dissipation and ductility of pipe pile components are little affected by different hoop ratio.
Deep length of pile will affect the seismic performance of pile.

And the morphologies of the initial aluminum films were found to be critical factors for successfully anodizing the Al film on 316L SS surface.
However, the polymer coating is subjected to mechanical damaged at the time of stent implantation [2].
Recently, porous DES, which was defined as endovascular stents with a surface or internal porosity that functioned as a reservoir for a continuous release of antirestenotic agents [5], has attracted wide attention due to its promising application potential in offering desirable drug elution properties as well as favorable clinical outcomes [6,7].
But up to now, there only a few technologies used to create porous stents, such as coating the stents with nanoporous aluminum oxide film [8] or manufacturing the stent surface or body itself by mechanical surface modification [9,10], and laser-cut manufacturing[6].
A further increase in the current density, as shown in Fig. 1c and d, seems fail to affect the morphology of the aluminum layer so much as in the case of lower current densities.

The material properties of electroplated NiW alloys with potential for use as emitters in thermionic energy converters were investigated.
NiW alloy films with W content ranging from 11 to 25 at% were electroplated and the material properties of the alloy films including their surface morphologies, and crystallinities, were determined.
Electroplated NiW alloys have good strength, hardness, wear-resistance, and their properties depend on W content in NiW alloy [5, 6].
Changes in the electron emission properties, crystal structure, and surface morphology were also examined with and without heat treatment.
Electroplated NiW alloys with different W content were prepared and their properties investigated.

It is equipped with an optical microscope that is used to study the texture, topography, and surface properties of powders or solids.
Acetylation time is one of the factors that affect the rate of reaction.
The reaction occurs when the particles crash with each other and cause collision thus affecting the degradation process of bacterial cellulose into cellulose acetate.
