Early-strength self-leveling concrete pavement rapid repair material and preparation method thereof
The invention discloses an early-strength self-leveling concrete pavement rapid repair material and a preparation method thereof. The material is prepared by mixing the following materials, by mass: 100 parts of a composite cement-based reinforcing material, 5-15 parts of fly ash, 5-15 parts of mineral powder, 0.1-0.5 part of polypropylene fiber, 0.15-0.35 part of a thickening time control component, 1-1.5 parts of a water reducing component and water. The rapid repair material is obtained through mutual cooperation and optimization of inorganic and organic components, and the graphite and theorganic water-soluble polyvinyl alcohol are added according to the mass ratio, so that the self-leveling property and permeability of the rapid repair material can be improved, and the toughness of the quick repair material is improved; the material has the characteristics of high hardening speed, high early strength, small shrinkage distortion, self-leveling property, high permeability, adjustable thickening time and the like. The material can be applied to pavement repair of highways, airports and the like, and overcome many defects of current similar products.
本发明公开了一种早强型自流平混凝土道面快速修补材料及制备方法，按以下质量份材料：复合水泥基增强材料100份、粉煤灰5～15份、矿粉5～15份、聚丙烯纤维0.1～0.5份、调凝组分0.15～0.35份、减水组分1～1.5份加水拌合而成。本发明为无机类与有机类组分相互协作优化而得，按质量比加入的石墨及有机类水溶性聚乙烯醇，可改善快速修补材料的自流平性、渗透性，提高快速修补材料的韧性；总体表现出硬化速度快，早期强度高，收缩变形小，自流平性、渗透性高、凝结时间可调等特点。本发明可应用于公路、机场等道面修补，弥补目前同类产品的诸多缺陷。
