    Assessment of the Mechanical Properties of Carbon-Fiber Heating Cables in Snow and Ice Melting Applications

    Zhiyong Yang1, Jiacheng Zhang1, Henglin Xiao1,2, Zhi Chen1,*, Tian Bao1, Yin Liu1

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.9, pp. 2267-2288, 2023, DOI:10.32604/fdmp.2023.028652

    Abstract The use of carbon-fiber heating cables (CFHC) to achieve effective melting of snow and ice deposited on roads is a method used worldwide. In this study, tensile and compressive tests have been conducted to analyze the mechanical properties of the CFHC and assess whether the maximum tensile and compressive strengths can meet the pavement design specifications. In order to study the aging produced by multiple cycles of heating and cooling, in particular, the CFHC was repeatedly heated in a cold chamber with an ambient temperature ranging between −20°C and +40°C. Moreover, to evaluate how the strength of the pavement is… 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 >

    Mechanical Properties of Lime-Fly Ash-Sulphate Aluminum Cement Stabilized Loess

    Liang Jia, Chunxiang Li, Jian Guo*

    Journal of Renewable Materials, Vol.8, No.10, pp. 1357-1373, 2020, DOI:10.32604/jrm.2020.012136

    Abstract Lime-fly ash stabilized loess has a poor early strength, which results in a later traffic opening time when it is used as road-base materials. Consideration of the significant early strength characteristics of sulphate aluminum cement (SAC), it is always added into the lime-fly ash mixtures to improve the early strength of stabilized loess. However, there is a scarcity of research on the mechanical behavior of lime-fly ash-SAC stabilized loess and there is a lack of quantitative evaluation of loess stabilized with binder materials. This research explored the effects of the amount of binder materials, curing time and porosity on the… More >

    Experimental Research on the Physical and Mechanical Properties of Concrete with Recycled Plastic Aggregates

    Haikuan Wu1,2, Changwu Liu1,2,*, Song Shi1,2, Kangliang Chen1,2

    Journal of Renewable Materials, Vol.8, No.7, pp. 727-738, 2020, DOI:10.32604/jrm.2020.09589

    Abstract In order to study the effect of recycled plastic particles on the physical and mechanical properties of concrete, recycled plastic concrete with 0, 3%, 5% and 7% content (by weight) was designed. The compressive strength, splitting tensile strength and the change of mass caused by water absorption during curing were measured. The results show that the strength of concrete is increased by adding recycled plastic into concrete. Among them, the compressive strength and the splitting tensile strength of concrete is the best when the plastic content is 5%. With the increase of plastic content, the development speed of early strength… More >
