Application of silicon carbide whisker in preparation of wear-resistant toughened anti-crack cement-based material
The invention provides an application of SiCw in preparation of a wear-resistant toughened anti-crack cement-based material. The application method comprises the following steps: mixing SiCw, water and a polycarboxylate superplasticizer, uniformly stirring, and sequentially carrying out ultrasonic dispersion and magnetic stirring dispersion to obtain a SiCw dispersion liquid; and adding the obtained SiCw dispersion liquid into a cement mixture to prepare the SiCw wear-resistant toughened anti-crack cement-based material. SiCw is doped into the cement-based material, so that the wear resistance, the toughness and the crack resistance of the cement-based material are remarkably improved, and the high cost required for structure detection and external repair of a concrete structure due to airshrinkage deformation and cracking can be reduced; the wear resistance of the cement-based material is remarkably enhanced, and the wear of a cement concrete pavement is reduced.
本发明提供了一种SiCw在制备耐磨增韧抗裂水泥基材料中的应用，所述应用的方法为：将SiCw、水、聚羧酸减水剂混合，搅拌均匀后依次经超声分散、磁力搅拌分散，得到SiCw分散液；将所得SiCw分散液加入水泥混合料中，制得SiCw耐磨增韧抗裂水泥基材料；本发明将SiCw掺入水泥基材料中，显著提升水泥基材料的耐磨性、韧性和抗裂性能，能够减少混凝土结构因干缩变形和开裂而引起的结构检测和外部修补所需的高额费用；显著增强水泥基材料的耐磨性，减轻水泥混凝土路面的磨损。
