Sound-absorbing noise-reducing light-weight high-strength concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses sound-absorbing noise-reducing light-weight high-strength concrete and a preparation method thereof. The invention relates to sound-absorbing noise-reducing lightweight high-strength concrete, which is prepared from the following raw materials in parts by weight: 380 to 420 parts of cement, 40 to 60 parts of fly ash, 75 to 90 parts of slag powder, 650 to 710 parts of ceramsite, 560 to 620 parts of steel slag, 2.8 to 3.4 parts of water reducing agent, 3.9 to 4.2 parts of foaming agent, 2 to 4 parts of foam stabilizer, 60 to 80 parts of fiber-based porous material and 115 to 130 parts of water. The fiber-based porous material comprises aramid fibers, silicon dioxide nanofibers and nanocellulose in a mass ratio of 1: (0.5-1): (0.1-0.5). The lightweight high-strength concrete has the advantages of good sound absorption and noise reduction effects, low density, light weight and high compressive strength.
本申请涉及建筑材料领域，具体公开了一种吸音降噪轻质高强混凝土及其制备方法。一种吸音降噪轻质高强混凝土，包括以下重量份的原料：380‑420份水泥、40‑60份粉煤灰、75‑90份矿渣粉、650‑710份陶粒、560‑620份钢渣、2.8‑3.4份减水剂、3.9‑4.2份发泡剂、2‑4份稳泡剂、60‑80份纤维基多孔材料、115‑130份水；所述纤维基多孔材料包括质量比为1:0.5‑1:0.1‑0.5的芳纶纤维、二氧化硅纳米纤维和纳米纤维素。本申请的轻质高强混凝土具有吸音降噪效果好，且密度小、质量轻、抗压强度大的优点。
