    Journal of Renewable Materials, Vol.11, No.8, pp. 3351-3370, 2023, DOI:10.32604/jrm.2023.027512

    Abstract In order to improve the comprehensive utilization rate of high fines sand (HFS) produced by the mine, full solid waste shotcrete (HFS-BFRS) was prepared with HFS as fine aggregate in cooperation with basalt fiber (BF). The strength growth characteristics of HFS-BFRS were analyzed. And the fitting equation of compressive strength growth characteristics of HFS-BFRS under the synergistic effect of multiple factors was given. And based on the orthogonal experimental method, the effects on the compressive strength, splitting tensile strength and flexural strength of HFS-BFRS under the action of different levels of influencing factors were investigated. The effect of three factors… More >

    Experimental Investigation on Fracture Performance of Short Basalt Fiber Bundle Reinforced Concrete

    Jinggan Shao1,2, Jiao Ma1, Renlong Liu1, Ye Liu3, Pu Zhang1,*, Yi Tang4, Yunjun Huang2

    Structural Durability & Health Monitoring, Vol.16, No.4, pp. 291-305, 2022, DOI:10.32604/sdhm.2022.015097

    Abstract In this paper, a notched three-point bending test is used to study the fracture performance of the short basalt fiber bundle reinforced concrete (SBFBRC). To compare and analyze the enhancement effect of different diameters and different content of basalt fiber bundles on the fracture performance of concrete, some groups are set up, and the P-CMOD curves of each group of specimens are measured, and the fracture toughness and fracture energy of each control group are calculated. The fracture toughness and fracture energy are two important fracture performance parameters to study the effect and law of the new basalt fiber bundles… More >

    Compressive Performance of Fiber Reinforced Recycled Aggregate Concrete by Basalt Fiber Reinforced Polymer-Polyvinyl Chloride Composite Jackets

    Zhijie Fan1, Huaxin Liu1, Genjin Liu2,*, Xuezhi Wang1, Wenqi Cui1

    Journal of Renewable Materials, Vol.11, No.4, pp. 1763-1791, 2023, DOI:10.32604/jrm.2023.024319

    Abstract 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… More > Graphic Abstract

    The Effect of Basalt Fiber on Concrete Performance under a Sulfate Attack Environment

    Qiang Su, Jinming Xu*

    Journal of Renewable Materials, Vol.11, No.1, pp. 233-244, 2023, DOI:10.32604/jrm.2023.020573

    Abstract To enhance the sulfate attack resistance performance of concrete, Sulfate erosion test was carried out on basalt fiber concrete with different contents, selecting a concentration of 5% sulfate solution and using a dry−wet cycle mechanism attack of basalt fiber-reinforced concrete (BFRC). Every 15 dry−wet cycles, the mass, compressive strength, splitting tensile strength, and relative dynamic elastic modulus of BFRC were tested, and the SO42− concentration was measured. This work demonstrates that the mass, relative dynamic elastic modulus, compressive and splitting tensile strength of BFRC reveal a trend of climb up and then decline with the process of the dry−wet cycle.… More >

    Damage and Deterioration Model of Basalt Fiber/Magnesium Oxychloride Composites Based on GM(1, 1)-Markov in the Salt Spray Corrosion Environment

    Jianqiao Yu1,*, Hongxia Qiao1,2, Theogene Hakuzweyezu1, Feifei Zhu1

    Journal of Renewable Materials, Vol.10, No.11, pp. 2973-2987, 2022, DOI:10.32604/jrm.2022.019620

    Abstract This study was designed to solve the problem of magnesium hazards due to potash extraction in the salt lake region. Using basalt fiber (BF) as the reinforcement material and magnesium oxychloride cement (MOC) as the gelling material, a BF/MOC composite material was prepared. Firstly, the effect of BF addition content on the basic mechanical properties of the composites was investigated. Then, through the salt spray corrosion test, the durability damage deterioration evaluation analysis was carried out from both macroscopic and microscopic aspects using mass change, relative dynamic modulus of elasticity (RDME) change, SEM analysis and FT-IR analysis. Finally, a GM(1,… More >

    Shear Strength Evaluation of Concrete Beams Reinforced with BFRP Bars and Steel fibers without Stirrups

    Smitha Gopinath1,2, S. Meenu3, A. Ramach,ra Murthy1

    CMC-Computers, Materials & Continua, Vol.51, No.2, pp. 81-103, 2016, DOI:10.3970/cmc.2016.051.081

    Abstract This paper presents experimental and analytical investigations on concrete beams reinforced with basalt fiber reinforced polymer (BFRP) and steel fibers without stirrups. Independent behaviour of BFRP reinforced beams and steel fiber reinforced beams were evaluated and the effect of combining BFRP bars and steel fiber was investigated in detail. It is found that combining steel fibers with BFRP could change the shear failure of BFRP reinforced beam to flexural failure. Further, the existing analytical models were reviewed and compared to predict the shear strength of both FRP reinforced and steel fiber reinforced beams. Based on the review, the appropriate model… More >
