Impact-resistant wear-resistant ultra-high performance concrete and application thereof
The invention relates to anti-impact wear-resistant ultra-high performance concrete which comprises the following components in parts by mass: 100 parts of a cementing material, 80-150 parts of ceramic sand, 1-8 parts of an additive, 14-24 parts of water and 0-30 parts of fibers. The preparation method comprises the steps that the waste sintered ceramic is crushed into ceramic sand, the ceramic sand serves as all fine aggregate to be used for preparing the ultra-high-performance concrete, the maximum particle size of the ceramic sand is 5 mm, and micron-sized pores are formed in the surface of the ceramic sand. The prepared ultra-high performance concrete can effectively improve impact resistance and wear resistance, compared with quartz sand aggregate ultra-high performance concrete, the anti-impact wear strength can be improved by 30% or above, the wear resistance of the ultra-high performance concrete can be improved by 40% or above, the ultra-high performance concrete is suitable for engineering parts with anti-impact wear and wear resistance requirements, waste sintered ceramics can be effectively recycled, and the cost is reduced. The economic and social benefits are obvious.
本发明涉及一种抗冲耐磨超高性能混凝土，以质量掺量比，包括以下组分，胶凝材料100份、陶瓷砂80‑150份、外加剂1‑8份、水14‑24份和纤维0‑30份。制备方法为将废弃烧成陶瓷破碎为陶瓷砂，以陶瓷砂作为全部细骨料用于制备超高性能混凝土，所述陶瓷砂的最大粒径为5mm，表面有微米级孔隙。本发明制得的超高性能混凝土能有效提高抗冲耐磨性能，与石英砂骨料超高性能混凝土相比，能够提高抗冲磨强度30％以上，提高其耐磨度40％以上，适用于有抗冲磨和耐磨要求的工程部位，并能有效的回收利用废弃烧成陶瓷，经济和社会效益显著。
