Fiber is the material of increasing the strength properties and is the role of increased material stiffness.
We can use additives to improve the resin matrix of the physical and chemical properties.
They thought that the surface of FRP reinforcement size, performance, and cement filler pipe anchorage stiffness were important factors affecting the performance bond.
In order to better apply the FRP tendons in prestressed concrete, and many scholars started their own mechanical properties.
In the course of its durability, we found that the higher the fiber content, the higher the intensity of FRP reinforcement, and the better its mechanical properties and durability[28].

The high-temperature corrosion of this weldment could be
one of the factors of the failure.
Since the selection of consumable plays a critical part in the improvement of the weldment properties, particularly the corrosion one, three different consumables were used.
The relationship between microstructure and properties, in both mechanical and corrosion aspects, of the weldments produced by different consumables were investigated for the purpose of selecting the most appropriate.

The enhancement in the gas-sensing properties was test by ethanol gas.
With a mechanical and a turbo pumps, the deposition chamber reached the base pressure at 1Í10-4 mTorr.
Results and discussion Microstructural Properties GIXRD patterns of the prepared TiO2 thin films are shown in Fig. 1.
Ethanol gas-sensing properties In this section, we examined the effect of the annealing treatment on the ethanol gas-sensing properties of the TiO2-based gas sensors.
The ethanol gas-sensing properties were investigated at different operating temperatures.

Road Input
Many interference factors affecting vehicle, which this paper only consider the effect of the road input.
Road roughness mainly USES the pavement power spectral density of describing the statistical properties [7]

The microstructures and
properties were investigated for PFM.
Table 1 shows the main properties of W, B4C and Cu.
Table 1 Main physical properties of W, B4C and Cu Property W B4C Cu Melting point, K 3680 2725 1357.6 Density, g/cm3 19.3 2.51 8.96 Thermal cond.
B4C/Cu Layered and Graded Coating for PFM The high melting point of B4C related to its excellent thermo- mechanical properties makes this low-Z material suitable for using as PFMs.
But, the water quenching tests showed that the graded coating had better heat quenching properties comparing with the others.

Rheology of Cement Slurry
Materials made of cement may help predict end-use performance and physical characteristics before and after processing by using rheological factors.
The Model 800 8-Speed Electronic Oilfield Viscometer is the equipment for rheological properties evaluation in this investigation.

This is somewhat difficult, since actually the material property values of a specific structure are not exact as those nominal values, they are influenced by several factors, such as manufacture process, temperature and others, inducing uncertainties to wave velocity.
In this study, a genetic algorithm (GA)-based approach is proposed for damage localization using measured ToF of the scattered Lamb wave without knowing the material properties and the theoretical wave velocity a priori.
Due to the dispersive nature of Lamb wave, the waveform of the scattered wave is always distorted, affecting the accuracy of measurement of ToF in time domain.
It is expected that when the minimization of J is achieved, the best estimation of the location of the damage and the wave velocity is obtained, thus the properties of the structure are not needed beforehand.
With the wave velocity of the scattered Lamb wave as a parameter to be identified, the material properties are not needed a priori.

Among steel types, where safety is
predominantly important they occupy distinguished place for their outstanding mechanical properties.
Besides outstanding mechanical properties their good weldability must be also considered.
Materials used TRIP steels have a non conventional chemical composition and mechanical properties.
Chemical Composition and Mechanical Properties of TRIP Steels are shown in Tables 1. and 2.
The steels properties which had been investigated by us are shown on Table 1.

Effect of basalt aggregate on the mechanical properties, deformations, thermal properties of concrete was studied in this paper.
The properties of two kinds of aggregates were showed in Table 1.
Results and discussions Effect of basalt aggregate on mechanical properties of concrete:In the case of approximate gradation and particle shape of aggregate, the crushing index and sturdiness of aggregate have greater influence on concrete strength.
Table 4 The thermal properties parameters of concrete No.
Due to the variety of factors to influence the shrinkage cracking of concrete, including strength, deformation, creep, and so on, there is no unified evaluation system to evaluate the crack resistance of concrete.
