| 1 | Bond Behavior between BFRP Bars and Hybrid Fiber Recycled Aggregate Concrete after High Temperature显示文摘The aim of this study is to improve the bond performance of basalt fiber reinforced polymer(BFRP)bars and recycled aggregate concrete(RAC)after being exposed to high temperatures.The bond behavior(failure modes,bond strength,bond stress-slip curves)between BFRP bars and hybrid fiber recycled aggregate concrete(HFRAC)after being exposed to temperatures ranging from 20℃up to 500℃was studied by using pull-out tests.The effect of high temperatures on mechanical properties of concrete(compressive strength,splitting tensile strength)and tensile strength of BFRP bars was also investigated.The bond strength decreased as the temperature increased and the drop of bond strength between RAC and BFRP bar was larger than that between HFRAC and BFRP bar.As the temperature rises,the key factor affecting the bond strength was gradually transformed from concrete strength to BFRP bar strength.The relationship between bond stress and slip in the dimensionless bond stress-slip ascending section was established,which was in good agreement with the experimental results. | Boheng Zhu Huaxin Liu Genjin Liu Abasal Hussain Xiaofei Zhang Xuezhi Wang | 2021 | Journal of Renewable Materials2021，9，3： | 2 |

| 3 | Compressive Performance of Fiber Reinforced Recycled Aggregate Concrete by Basalt Fiber Reinforced Polymer-Polyvinyl Chloride Composite Jackets显示文摘The development of recycled aggregate concrete(RAC)provides a new approach to limiting the waste of natural resources.In the present study,the mechanical properties and deformability of RACs were improved by adding basalt fibers(BFs)and using external restraints,such as a fiber-reinforced polymer(FRP)jacket or a PVC pipe.Samples were tested under axial compression.The results showed that RAC(50%replacement of aggregate)containing 0.2%BFs had the best mechanical properties.Using either BFs or PVC reinforcement had a slight effect on the loadbearing capacity and mode of failure.With different levels of BFs,the compressive strengths of the specimens reinforced with 1-layer and 3-layer basalt fiber reinforced polymer(BFRP)increased by 6.7%–10.5%and 16.5%–23.7%,respectively,and the ultimate strains increased by 48.5%–80.7%and 97.1%–141.1%,respectively.The peak stress of the 3-layer BFRP-PVC increased by 42.2%,and the ultimate strain improved by 131.3%,relative to the control.This reinforcement combined the high tensile strength of BFRP,which improved the post-peak behavior,and PVC,which enhanced the structural durability.In addition,to investigate the influence of the various constraints on compressive behavior,the stress-strain response was analyzed.Based on the analysis of experimental results,a peak stress-strain model and an amended ultimate stress-strain model were proposed.The models were verified as well;the result showed that the predictions from calculations are generally consistent with the experimental data(error within 10%).The results of this study provide a theoretical basis and reference for future applications of fiber-reinforced recycled concrete. | Zhijie Fan Huaxin Liu Genjin Liu Xuezhi Wang Wenqi Cui | 2023 | Journal of Renewable Materials2023，11，4： | 0 |
| 4 | Chengdu’s Smart Manufacturing in the New Era:Achievements and Optimization显示文摘The promotion of smart manufacturing is a crucial move that will enable Chengdu to build a major growth pole for high-quality national development and shape a new growth powerhouse.In recent years,Chengdu’s capability has made marked progress in smart manufacturing,significantly enhancing the capability for independent innovation,gradually optimizing development factor allocations,relentlessly strengthening pilot and demonstration effects,and constantly emerging collaborative service platforms.The development of Chengdu’s smart manufacturing can be summarized in four points:taking a holistic approach to top-down design,raising policy incentives for innovative talents,creating a favorable environment for industrial innovation,and building service platforms to promote innovation.In the new era,Chengdu should continue to explore the best possible path to smart manufacturing and target high-quality development of local manufacturing industries by making the following efforts:a)optimizing top-down design for better policy guidance;b)focusing on technological innovation to improve corresponding innovation capability;c)forging service platforms to break barriers to development;d)strengthening lateral communications to promote collaborative transformation;and e)building leading enterprises and brands native to Chengdu. | Sun Genjin Gao Rui Liu Ying | 2022 | Contemporary Social Sciences2022，7，3： | 0 |
