Underwater concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses underwater concrete and a preparation method thereof. The underwater concrete is prepared from the following raw materials in parts by weight: 300 to 400 parts of medium sand, 600 to 750 parts of gravel, 120 to 280 parts of cement, 5 to 15 parts of inorganic polymeric flocculant, 5 to 10 parts of water reducing agent, 100 to 250 parts of water, 15 to 45 parts of mineral admixture and 10 to 25 parts of impermeable modified polypropylene reticular fiber, the impervious modified polypropylene reticular fibers are obtained by surface modification of polypropylene reticular fibers with an SY-K expansive fiber anti-crack waterproof agent; the preparation method comprises the following steps: mixing and stirring the raw materials except the water and the impermeable modified polypropylene reticular fibers; then adding the impermeable modified polypropylene reticular fibers and stirring; and finally adding water, mixing and stirring to obtain the underwater concrete. The underwater concrete has the advantage of effectively improving the impermeability of the underwater concrete.
本申请涉及建筑材料的领域，具体公开了一种水下混凝土及其制备方法。一种水下混凝土，包括以下重量份的原料：中砂300‑400份，碎石600‑750份，水泥120‑280份，无机高分子絮凝剂5‑15份，减水剂5‑10份，水100‑250份，矿物外加剂15‑45份，抗渗改性聚丙烯网状纤维10‑25份；且抗渗改性聚丙烯网状纤维由聚丙烯网状纤维经SY‑K膨胀纤维抗裂防水剂表面改性得到；其制备方法为：将除水和抗渗改性聚丙烯网状纤维外的原料混合后搅拌；之后加入抗渗改性聚丙烯网状纤维搅拌；最后加入水混合搅拌得到水下混凝土。本申请一种水下混凝土具备有效改善水下混凝土抗渗性能的优点。
