Anti-crack concrete and preparation method thereof
The invention discloses anti-crack concrete and a preparation method thereof. The anti-crack concrete is technically characterized by comprising 600 to 800 parts of coarse aggregate, 500 to 650 parts of fine aggregate, 150 to 300 parts of cement, 0.6 to 2 parts of a water reducing agent, 60 to 80 parts of filler, 15 to 20 parts of modified wood fibers and 160 to 190 parts of water. The modified wood fibers are obtained by modifying wood fibers through silica sol. The 60-80 parts of the filler is prepared from the following raw materials in parts by weight: 50 to 60 parts of porous hollow microspheres and 10 to 20 parts of paraffin. The concrete of the invention has the advantage of improved crack resistance.
本申请公开了一种抗裂混凝土及其制备方法，其技术要点是：包括粗骨料600‑800份；细骨料500‑650份；水泥150‑300份；减水剂0.6‑2份；填料60‑80份；改性木纤维15‑20份；水160‑190份；上述所述改性木纤维是将木纤维通过硅溶胶改性得到；上述60‑80份的所述填料包括如下重量份数的原料制成：多孔空心微球50‑60份；石蜡10‑20份。本申请具有提高混凝土的抗裂性能的优点。
