Ultra-high-performance anti-impact wear-resistant concrete and preparation method thereof
The invention discloses ultra-high-performance anti-impact wear-resistant concrete and a preparation method thereof, and the ultra-high-performance anti-impact wear-resistant concrete is prepared by mixing the following components in parts by weight: 40-60 parts of a rubber material, 0-12 parts of fine aggregate, 40-60 parts of coarse aggregate, 0.45-0.9 part of an additive, 4-6 parts of water and fibers accounting for 0.1-0.3% of the total volume of the rubber material, the fine aggregate, the coarse aggregate and the additive. The adhesive material, the fine aggregate and the additive are uniformly mixed in a dry manner, the fibers are added and then are uniformly distributed in a dry manner, and then the coarse aggregate and the water are added and stirred. The problems that common hydraulic concrete is prone to overflowing surface abrasion and cavitation erosion under long-term scouring of high-speed mud-clamping, sand-clamping and stone-clamping water flow are solved, large-area denudation of surface concrete is avoided, the mechanical property, durability and anti-impact and wear-resistant strength of the concrete are improved, and the service life of a building is prolonged.
本发明公开了一种超高性能抗冲耐磨混凝土及其制备方法，其组分以重量份计，包括胶材40～60份、细骨料0～12份、粗骨料40～60份、外加剂0.45～0.9份、水4～6份，及占胶材、细骨料、粗骨料、外加剂总体积的0.1％～0.3％的纤维混合而成。将上述胶材、细骨料、外加剂干拌均匀，加入纤维后进行干拌使其均匀分布，再加入粗骨料和水搅拌制备而成。本发明解决了普通水工混凝土在高速夹泥、夹砂、夹石水流长期冲刷下易发生过流面磨蚀及空蚀现象，避免了表层混凝土大面积剥蚀，提高了混凝土的力学性能、耐久性能及抗冲耐磨强度，提高了建筑的使用寿命。
