| 1 | Unveiling the Carbonation Behavior and Microstructural Changes of Magnesium Slag at 0℃显示文摘Magnesium slag(MS)is an industrial byproduct with high CO_(2)sequestration potential.This study investigates the carbonation behavior and microstructural changes of MS during wet carbonation at 0℃.XRD,TG,FTIR,SEM,and BET techniques were used to characterize the phase composition,microstructure,and porosity of MS samples carbonated for different durations.The results showed that the main carbonation products were calcite,vaterite,and highly polymerized silica gel,with particle sizes around 1μm.The low-temperature environment retarded the carbonation reaction rate and affected the morphology and crystallization of calcium carbonate.After 480 min of carbonation,the specific surface area and porosity of MS increased substantially by 740%and 144.6%,respectively,indicating improved reactivity.The microstructure of carbonated MS became denser with calcite particles surrounded by silica gel.This study demonstrates that wet carbonation of MS at 0℃significantly enhances its properties,creating an ultrafine supplementary cementitious material with considerable CO_(2)sequestration capacity. | Junhao Ye Songhui Liu Jingrui Fang Xuemao Guan Hui Guo | 2023 | Journal of Building Material Science2023，5，2： | 0 |
| 2 | Trusted Virtual Machine Model Based on High-Performance Cipher Coprocessor显示文摘In the cloud computing environment,with the complex network environment,the virtualization platform faces many security problems.At the same time,trusted computing can greatly enhance the architecture security of virtualization platform systems,but there are many problems when trusted computing is deployed directly in the cloud environment.Therefore,this paper proposes a trusted virtual machine model based on high-performance cipher coprocessor to solve the security problems such as the isolation and insufficient performance of virtual TPM(vTPM)on the existing virtual platform.In this model,virtio technology was used to realize the virtualization of TPM,and a management architecture was designed to manage the life cycle of vTPM.The analysis shows that the model can complete the isolation of vTPM,and protect the security of vTPM during the migration process through the migration control server,and can strengthen the security of the virtualization platform.Finally,the simulation results show that the model is more feasible and suitable for cloud platform than hardware TPM. | Haidong Liu Songhui Guo Lei Sun Song Guo | 2020 | 国际计算机前沿大会会议论文集2020，，1： | 0 |
| 3 | Effects of LiAl-Layered Double Hydroxides on Early Hydration of Calcium Sulphoaluminate Cement Paste显示文摘As a 3D micro-nano material, layered double hydroxides have been widely used in many fields, especially for reinforced composite materials. In this paper, Li Al-LDHs was obtained by a hydrothermal method. In order to investigate the effects of Li Al-LDHs on the early hydration of calcium sulphoaluminate(CSA) cement paste, compressive strength, setting time and hydration heat were tested while X-ray diffraction(XRD), Fourier transform infrared spectroscopy(FT-IR), scaning electron microscopy(SEM) and differential scanning calorimetry(DSC) analysis were employed. The results indicated that Li Al-LDHs could significantly improve the early compressive strength and shorten the setting time of calcium sulphoaluminate cement paste with 3 wt% concentration. Besides, the hydration exothermic rate within 5h was accelerated with increasing Li Al-LDHs content. Moreover, the addition of Li Al-LDHs did not result in the formation of a new phase, but increased the quantity of hydration products providing higher compressive strength, shorter setting time and denser microstructure. | 李海艳 管学茂 YANG Lei LIU Songhui ZHANG Jianwu GUO Yanan | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，5： | 0 |
