Different types of steel fibers with variations of addition volumes were applied to the concrete mixtures and various kinds of mechanical properties such as strength, toughness, and fracture energy were evaluated.
The workability and mechanical properties of each FRC mixture were evaluated and the effects of fiber types and addition volumes were observed.
This is because the structural design is fundamentally based on the mechanical properties under static loading conditions.
As a preliminary study, in order to observe the effects of fiber types and fiber volumes on the changes of mechanical properties of FRC mixtures, and for future studies related to the changes of dynamic increase factors due to fiber reinforcements, the single type of concrete mixture that is currently used for nuclear power plants (especially for containments) in Korea was chosen as a base concrete mixture.
Also, three different volume fractions (Vf = 0.5, 0.75, and 1.0%) were applied to permit observation of the effects of fiber volume on the variations of mechanical properties of the FRC mixtures.

Introduction CO2 partial pressure is one of the important influence factors on CO2 corrosion, the PH value of solution or the concentration of a series of chemical compound of CO2 dissolved in the solution will exert an influence directly and further affect the rate of corrosion [1-2].
Due to excellent corrosion resistance, good mechanical properties and free of contamination, polyurea coatings are widely used in industrial antisepsis and mechanical wear protection lining areas [3-5].
The first time constant is the constant of coating properties, and the second time constant is a time constant of the electrical double layer.
This indicates that after the high-pressure high-temperature corrosion, the protective properties of the coating greatly reduced, generates serious corrosion, and the occurrence of dual capacitive impedance arc indicates that the corrosion resistance effect of the polyurea coating is basically lose, the corrosion resistance process transfers from the control process of the coating gaps through the corrosion medium into the charge transit process control of corrosion of the metal substrate.

Presenting novel approaches, the paper emphasizes the crucial role of reproducible experiments to elucidate the scale properties coupled with numerical analysis to develop quantitative models with predictive accuracy.
The research quickly revealed that the oxide scale on the hot metal undergoing plastic deformation would need to be treated as a detailed material, not just a homogeneous layer with nominal properties.
Understanding the scale removal mechanism is important for optimisation of industrial mechanical descaling conditions when bending, tension and compression at room temperature are operational factors influencing scale spallation.
The main mathematical assumptions of the model related to oxide scale and implemented properties of materials have been described elsewhere [12].

Introduction A machine tool is a powered mechanical device, typically used to fabricate metal components of machines by machining, which is the selective removal of metal.
In the processing of manufacturing, the rising of temperature caused by friction heat, cutting heat, ambient temperature and other factors will lead to thermal deformation of the driving components of machine tool, so that the correct position between the tool and work piece will be changed.
Generally the inaccuracy of machine is caused by the following factors
The key point in this research is to study the thermal induced deformation and the major factors are temperature difference and material properties which are not affected by above errors, thus, we can say that the simulated temperature distribution is acceptable and could be used as boundary conditions for further structure simulation.
