Ultrahigh wear-resistant concrete and preparation method thereof
The invention relates to the technical field of concrete materials, and discloses ultrahigh wear-resistant concrete, which is prepared from the following raw materials in parts by weight: 300 to 900 parts of cement, 100 to 150 parts of silicon powder, 1 to 5 parts of nanometer materials, 600 to 1100 parts of millimeter-sized wear-resistant aggregates, 200 to 400 parts of micron-sized wear-resistant fillers, 15 to 30 parts of wear-resistant fibers, 200 to 350 parts of steel fibers, 5 to 15 parts of additives and 90 to 120 parts of water. The preparation method comprises the following steps: vibrating, stirring and dispersing the cement, the silicon powder, the nano material, the wear-resistant filler and the wear-resistant aggregate to obtain dry powder; mixing water, an additive and the dry powder, and uniformly stirring to prepare a slurry material; adding wear-resistant fibers and steel fibers into the slurry material, and uniformly stirring to obtain slurry; pouring the slurry material into a mold, and removing the mold after the slurry material is hardened to obtain a test piece; the prepared concrete can still have ultrahigh wear resistance in complex and severe environments such as high temperature, high stress, high erosion and the like.
本发明涉及混凝土材料技术领域，公开了一种超高耐磨型混凝土，包括如下重量份的原料：水泥300‑900份、硅粉100‑150份、纳米材料1‑5份、毫米级耐磨骨料600‑1100份、微米级耐磨填料200‑400份、耐磨纤维15‑30份、钢纤维200‑350份、外加剂5‑15份和水90‑120份，并公开了该混凝土的制备方法，包括将水泥、硅粉、纳米材料、耐磨填料和耐磨骨料进行振动搅拌分散，获得干粉料；将水、外加剂和干粉料混合后搅拌均匀，制得浆体物料；将耐磨纤维和钢纤维加入浆体物料中并搅拌均匀，获得浆体；将浆体物料浇筑至模具中，待浆体物料硬化后拆模得到试件；对试件进行养护，制得的混凝土能够在高温、高应力和高侵蚀等复杂恶劣环境下，仍然具有超高的耐磨性能。
