Preparation process and construction method of waterproof, anti-corrosion and anti-seepage concrete
The invention relates to a preparation process and a construction method of waterproof, anticorrosive and anti-seepage concrete, the feeding sequence of a stirrer adopts a two-feeding method, and the feeding sequence during construction comprises the following steps: firstly, feeding fine aggregate, cement, fly ash and mineral powder into the stirrer; the preparation method comprises the following steps: mixing the raw materials, adding SY-KS multifunctional anti-erosion preservative, SY-K expansive fiber anti-crack waterproof agent, PH-A modified polypropylene anti-crack fiber and other admixtures, stirring for 30 seconds, adding water for stirring, stirring for 40 seconds, finally adding coarse aggregate, stirring for 60 seconds, and controlling the total stirring time of the concrete to be about 130 seconds. According to the invention, generation and development of micro cracks and communication cracks are inhibited. Meanwhile, the addition of countless fiber monofilaments can effectively hinder the segregation of the aggregate, and ensures the early uniform bleeding property of the concrete, thereby hindering the formation of settlement cracks.
本发明涉及一种防水防腐抗渗混凝土的制备工艺及其施工方法，搅拌机投料顺序采用二投料法，施工时的投料顺序为：先向搅拌机投入细骨料、水泥、粉煤灰、矿粉，再加入SY‑KS多功能抗侵蚀防腐剂、SY‑K膨胀纤维抗裂防水剂、PH‑A改性聚丙烯抗裂纤维等外加剂拌合30s,加入拌和用水拌合40s,最后再加入粗骨料进行拌合60s,混凝土总搅拌时间控制在130s左右。本发明抑制了微细裂缝、连通裂缝的产生的产生和发展。同时，无数纤维单丝的加入可有效阻碍骨料的离析，保证了混凝土早期的均匀泌水性，从而阻碍了沉降裂纹的形成。
