    Experimental Study on Abrasion Resistance of Self-Compacting Concrete

    Weixi Zhu1,2,3, Yongdong Meng1,3,*, Jindong Xie2, Zhenglong Cai1,3, Yu Lyu2, Xiaowei Xu1,3

    Structural Durability & Health Monitoring, Vol.19, No.6, pp. 1733-1744, 2025, DOI:10.32604/sdhm.2025.070098 - 17 November 2025

    Abstract To mitigate the severe abrasion damage caused by high-velocity water flow in hydraulic engineering applications in Xizang, China, this study systematically optimized key mix design parameters, including aggregate gradation, sand ratio, fly ash content, and superplasticizer dosage. Based on the optimized mix, the combined effects of an abrasion-resistance enhancement admixture (AEA) and silica fume (SF) on the abrasion resistance of self-compacting concrete (SCC) were examined. The results demonstrated that the appropriate incorporation of AEA and SF significantly improved the abrasion resistance of SCC without compromising its workability. The proposed mix design not only achieves superior… More >

    An Abrasion Resistant TPU/SH-SiO2 Superhydrophobic Coating for Anti-Icing and Anti-Corrosion Applications

    Jiakun Shi1, Bizhu Zhang1, Xin Zhou1, Runxian Liu1, Jun Hu1,2,*, Huaan Zheng1, Zhong Chen3,*

    Journal of Renewable Materials, Vol.10, No.5, pp. 1239-1255, 2022, DOI:10.32604/jrm.2022.018045 - 22 December 2021

    Abstract As a passive anti-icing strategy, properly designed superhydrophobic coatings can demonstrate outstanding performances. However, common preparation strategies for superhydrophobic coatings often lead to environmental pollution, high energy-consumption, high-cost and other undesirable issues. Besides, the durability of superhydrophobic coating also plagues its commercial application. In this paper, we introduced a facile and environment-friendly technique for fabricating abrasion-resistant superhydrophobic surfaces using thermoplastic polyurethane (TPU) and modified SiO2 particles (SH-SiO2). Both materials are non-toxicity, low-cost, and commercial available. Our methodology has the following advantages: use of minimal amounts of formulation, take the most streamlined technical route, and no waste… More > Graphic Abstract
