Anti-seepage and anti-cracking concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses anti-seepage and anti-cracking concrete and a preparation method thereof. The anti-seepage and anti-cracking concrete is prepared from the following raw materials: cement, coarse aggregate, fine aggregate, water, volcanic ash, fiber aggregate, maleic anhydride, allyl polyoxyethylene ether, polytetrahydrofuran, ammonium persulfate and polypropylene glycol. The preparation method comprises the following steps: 1) uniformly mixing maleic anhydride, allyl polyoxyethylene ether, polytetrahydrofuran, ammonium persulfate and polypropylene glycol, and performing constant-temperature treatment to obtain a fiber modifier; 2) cooling the fiber modifier and adding the fiber aggregate for stirring to obtain improved fiber aggregate; and 3) uniformly mixing the volcanic ash, the cement, the water, the coarse aggregate, the fine aggregate and the improved fiber aggregate to obtain the anti-seepage and anti-cracking type concrete.The prepared anti-seepage and anti-cracking type concrete has excellent anti-seepage performance and anti-cracking performance.
本申请涉及混凝土领域，具体公开了一种抗渗防裂型混凝土及其制备方法。一种抗渗防裂型混凝土包括以下原料组成：水泥、粗集料、细集料、水、火山灰、纤维集料、马来酸酐、烯丙基聚氧乙烯醚、聚四氢呋喃、过硫酸铵以及聚丙二醇。其制备方法为：1）将马来酸酐、烯丙基聚氧乙烯醚、聚四氢呋喃、过硫酸铵、聚丙二醇混合均匀后恒温处理，获得纤维改性剂；2）将纤维改性剂降温并投入纤维集料搅拌，获得改良纤维集料；3）将火山灰、水泥、水、粗集料、细集料与改良纤维集料混合均匀，获得抗渗防裂型混凝土。本申请制得的抗渗防裂型混凝土具有优良的抗渗性能与防裂性能。
