High-strength anti-crack concrete and preparation method thereof
The invention relates to a high-strength anti-crack concrete and a preparation method thereof. The high-strength anti-crack concrete comprises, by weight, 500 to 600 parts of sands; 400 to 600 parts of fine stone; 300 to 600 parts of cement; 50 to 100 parts of fly ash; 130 to 140 parts of water; 0.5 to 1.5 parts of a reinforcing agent; and 100 to 150 parts of a modified fiber filler. The modified fiber filler is prepared by the following steps: a, pretreating: heating and mixing polyester fibers and glass fibers, and performing vacuum freeze drying to obtain mixed fibers; and b, modifying: heating and mixing the mixed fibers, the modified sol and a coupling agent to obtain the modified fiber filler. The modified sol is prepared from mixed resin and filler; and the mixed resin is prepared from hyperbranched polyacrylate, amino resin and polybutadiene epoxy resin. The concrete prepared in the invention has the advantage of high crack resistance.
本申请涉及一种高强抗裂混凝土及其制备方法，其包括如下重量份数的组分：砂子500‑600份；细石400‑600份；水泥300‑600份；粉煤灰50‑100份；水130‑140份；增强剂0.5‑1.5份；改性纤维填料100‑150份；改性纤维填料由以下步骤制备获得：a、预处理：将涤纶纤维与玻璃纤维加热混合后，真空冷冻干燥，制得混合纤维；b、改性：将混合纤维、改性溶胶和偶联剂加热混合，即可制得改性纤维填料；所述改性溶胶由混合树脂和填料组成；所述混合树脂由超支化聚丙烯酸酯、氨基树脂、聚丁二烯环氧树脂组成。本申请中制得的混凝土，具有高抗裂性的优点。
