| 1 | 玄武岩-聚丙烯混杂纤维混凝土硫酸盐腐蚀试验研究显示文摘通过对单掺和三种不同混杂比例混掺的方式,以体积掺加率0.3%、0.6%、0.9%、1.2%将玄武岩、聚丙烯纤维掺入普通C30混凝土中形成混杂纤维混凝土,对其进行7d、14d、28d龄期的抗硫酸盐腐蚀性能试验研究。结果表明,对基体混凝土在龄期为7d的抗压强度耐蚀系数提高最为显著的是单掺纤维系列与1:1、1:2混杂纤维系列纤维混凝土。各系列纤维对基体混凝土14d耐蚀系数提高的最佳纤维掺加率在0.3%附近;单掺聚丙烯纤维系列、单掺玄武岩纤维系列对基体28d耐蚀系数提高的最佳纤维掺加率分别在0.3%、0.9%附近。总体上混杂纤维系列纤维混凝土的抗硫酸静泡腐蚀能力优于单掺纤维系列纤维混凝土。 | 王学志 贺晶晶 邹浩飞 郑淑文 Mustapha Abdulhadi | 2014 | 混凝土与水泥制品2014，，5： | 15 |
| 2 | Stress-dependent shear wave splitting and permeability in fractured porous rock显示文摘It is well known that shear wave propagates slower across than parallel to a fracture, and as a result, a travelling shear wave splits into two directions when it encounters a fracture. Shear wave splitting and permeability of porous rock core samples having single fracture were experimentally investigated using a high-pressure triaxial cell, which can measure seismic shear wave velocities in two directions mutually perpendicular to the sample axis in addition to the longitudinal compressive wave velocity. A single fracture was created in the samples using a modified Brazilian split test device, where the cylindrical sample edges were loaded on two diametrically opposite lines by sharp guillotines along the sample length. Based on tilt tests and fracture surface profilometry, the method of artificially induced tensile fracture in the sample was found to create repeatable fracture surfaces and morphologies. Seismic velocities of the fractured samples were determined under different levels of stress confinement and fracture shear displacement or mismatch. The effective confining stress was varied from 0.5 MPa to55 MPa, while the fractures were mismatched by 0 mm, 0.45 mm and 1 mm. The degree of matching of the fracture surfaces in the core samples was evaluated using the joint matching coefficient(JMC). Shear wave splitting, as measured by the difference in the magnitudes of shear wave velocities parallel(V_(S1))and perpendicular(V_(S2)) to the fracture, is found to be insensitive to the degree of mismatching of the fracture joint surfaces at 2 MPa, and decreased and approached zero as the effective stress was increased.Simple models for the stress-and JMC-dependent shear wave splitting and fractured rock permeability were developed based on the experimental observations. The effects of the joint wall compressive strength(JCS), JMC and stress on the stress dependency of joint aperture were discussed in terms of hydro-mechanical response. Finally, a useful relationship between fractured rock permeability and shear wave splitting was found after normalization by using JMC. | Daisuke Katsuki Marte Gutierrez Abdulhadi Almrabat | 2019 | Journal of Rock Mechanics and Geotechnical Engineering2019，11，1： | 3 |
| 3 | Dielectric and microstructural properties of YAG:Dy^(3+) ceramics显示文摘Yttrium aluminium garnet(Y_3 Al_5 O_(12):YAG) singly doped with Dy3+ at different concentrations was prepared by solid state reactions using repeated heating cycles over the temperature range of 1300-1600 ℃. X-ray powder diffraction analysis confirms the presence of a well-crystallized YAG perovskite phase with cubic structure(by Rietveld refinement). The rare earth dopant is successfully integrated into the YAG host lattice without any major changes in the original structure. The temperature dependence,up to 250 ℃, of the conductivity, dielectric constant, dielectric loss, and loss tangent, at various frequencies of up to 5.0 MHz for undoped and doped crystals is compared to understand the electrical and structural characteristics. The experimental results reveal that Dy3+ dopants in YAG crystal significantly influence the conductivity, dielectric constant, and lossy mechanisms, which is probably due to the 3 d-AI ions and 4 f-Dy ions incorporated at different positions of both tetrahedral and octahedral symmetries in YAG:xDy3+ ceramics. | Munirah Abdullah Almessiere Bayram Unal Abdulhadi Baykal | 2018 | Journal of Rare Earths2018，36，12： | 2 |
