Fiber-blended ultra-high performance concrete material and preparation method thereof
The invention discloses a fiber-blended ultra-high-performance concrete material and a preparation method thereof. The fiber-blended ultra-high-performance concrete material comprises a composite cementing material, aggregate, an auxiliary agent and fibers. The composite cementing material comprises the following components in parts by weight: 600-900 parts of cement, 50-200 parts of mineral powder or fly ash and 80-200 parts of silica fume. The aggregate is prepared from the following components in parts by weight: 400 to 800 parts of sand of 20 to 40 meshes, 150 to 400 parts of sand of 40 to 70 meshes and 100 to 200 parts of sand of 325 meshes; the auxiliary agent is prepared from the following components in parts by weight: 50 to 120 parts of a water reducing agent, 0.05 to 0.4 part of a de-foaming agent, 0.3 to 0.8 part of a stabilizing agent, 0.01 to 0.1 part of a wetting dispersant and 100 to 150 parts of water; and 10 to 24 parts of fiber. The fiber-blended ultra-high performance concrete provided by the invention meets the mechanical property requirement of a building outer wall decorative plate, and also greatly reduces the manufacturing cost of the plate.
本发明公开了一种混掺纤维超高性能混凝土材料及其制备方法，包括复合胶凝材料、骨料、助剂以及纤维。复合胶凝材料包括以下重量份的组分：水泥600‑900份，矿粉或粉煤灰50‑200份，硅灰80‑200份；骨料包括以下重量份的组分：20‑40目砂400‑800份，40‑70目砂150‑400份，325目砂100‑200份；助剂包括以下重量份的组分：减水剂50‑120份，消泡剂0.05‑0.4份，稳定剂0.3‑0.8份，润湿分散剂0.01‑0.1份，水100‑150份；纤维：10‑24份。本发明的混掺纤维超高性能混凝土在满足建筑外墙装饰板力学性能要求的同时，也使得板材的造价大大降低。
