concrete. For the TRC with a single layer of textile, the average shear strength tended to decrease with increasing bond length. In addition, the strength grade of the existing concrete had a minor... (FRP) wraps has become popular due to the favorable properties of this retrofitting method: extremely low weight-to- strength ratio, easy application, minimal change in the structure behavior......
[24-29]. A comparison of shear behavior under different boundary conditions indicated that shear strength was underestimated and dilation was overestimated under the CNL conditions, especially at low... and fragment during this experiment. Pulverized and crushed grain resulting from shearing abrasion and shearing off the second-order asperity were primary asperity failure mode for bolted joint......

the fractal characteristics of shale and coal using low-pressure N2 adsorption and NMR. Fractal theory, which uses a fractal dimension to quantitatively analyze the uniformity of a pore network, has been... fractal pore structure and analyzed the fluidity and exudation of fresh cement paste based on low-field NMR. An original method for calculating surface fractal dimensions of fresh cement paste based on low......
and WILLIAMS [3] reported that the microstructure after the primary deformation in the β region contains β grains with various sizes surrounded by the α phase boundaries. Moreover, the lamellar α phase.... Moreover, deformation heating due to the low thermal conductivity relative to other metals has a significant effect on flow stress during hot deformation. Hence, the flow behavior of the alloy was analyzed......

moisture migration, considering that the low annual rainfall, deep groundwater level and strong evaporation in these areas [1-4]. For subgrade soil, water vapor migration will cause water to accumulate... on the temperature, the concentration of the aqueous solution, and the moisture content of the soil [14-19]. Under non-isothermal conditions,water vapor will migrate from high to low temperature......
and Zr-25%Ta-5%Ti alloy prepared by spark plasma sintering (SPS) technology were investigated. The experimental results showed that the Zr-Ta-Ti alloys made by the SPS processing have a low level...-Ta alloys exhibited low elastic modulus, good corrosion resistance and excellent biocompatibility [17]. It is revealed that Ti reduces the elastic modulus of Zr alloys and Ta alloys, and improves......
