Seawater-resistant concrete repairing material and preparation method thereof
The invention provides a seawater-resistant concrete repairing material which is composed of two parts of ingredients, namely a repairing high-viscosity concrete ingredient M1 and a salt-resistant antibacterial compact concrete ingredient M2. The repairable high-viscosity concrete ingredient M1 is prepared from 55 to 65 weight percent of modified magnesium phosphate cement, 1.5 to 2.5 weight percent of ternary copolymerized polyacrylamide, 25 to 35 weight percent of quartz sand with the fineness modulus of 2.5 to 2.7 and 5 to 10 weight percent of superfine steel fiber with the cross sectional area of less than or equal to 0.01 mm < 2 >; the salt-tolerant antibacterial compact concrete ingredient M2 is prepared from the following components in percentage by weight: 55 to 60 percent of modified magnesium phosphate cement, 0.4 to 0.8 percent of ternary copolymer polyacrylamide, 10 to 20 percent of coarse aggregate, 10 to 15 percent of fine aggregate, 5 to 10 percent of common steel fiber, 0.1 to 0.5 percent of water reducing agent and 0.01 to 0.5 percent of cuprous oxide. By matching the two concrete ingredients, the repair effect with stable and excellent performance can be obtained.
本申请提供了一种耐海水的混凝土修补材料，由两部分配料组成，分别是修复性高粘结混凝土配料M1和耐盐抗菌性致密混凝土配料M2。修复性高粘结混凝土配料M1的组成为55‑65wt.％的改性磷酸镁水泥、1.5‑2.5wt.％的三元共聚聚丙烯酰胺、25‑35wt.％的细度模数为2.5‑2.7的石英砂、5‑10wt.％的横截面积小于等于0.01mm2的超细钢纤维；耐盐抗菌性致密混凝土配料M2的组成为55‑60wt.％的改性磷酸镁水泥、0.4‑0.8wt.％的三元共聚聚丙烯酰胺、10‑20wt.％粗集料、10‑15wt.％细集料、5‑10wt.％的普通钢纤维、0.1‑0.5wt.％的减水剂、0.01‑0.5wt.％的氧化亚铜。通过将两者设定的混凝土配料配合使用，可以获得性能稳定优异的修补效果。
