Rapid repairing agent for shield segment
The invention relates to the technical field of repairing materials, and discloses a shield segment rapid repairing agent which comprises a component A and a component B. The component A is a polymer emulsion, the component B is an early-strength high-strength anti-cracking anti-seepage premix, the mass ratio of the component A to the component B is 1: 6, and the component B is composed of, by mass, special cement, quartz sand and superfine mineral powder. The concrete is prepared from the following raw materials: silica fume, redispersible latex powder, special fibers, a water-retaining thickener, a water reducer and a nano anti-permeability agent. The rapid repairing agent for the shield segment is a cement-based composite material modified by silicone acrylic emulsion, not only retains the advantages of easy availability, good durability, environmental friendliness and relatively low price of an inorganic material, but also plays the advantages of high bonding strength and flexibility of a high polymer material, and is specially used for repairing defects of the concrete shield segment.
本发明涉及修补材料技术领域,且公开了一种盾构管片快速修补剂,包括A组分和B组分,所述A组分为聚合物乳液,所述B组分为早强高强抗裂抗渗预混料,所述A∶B的质量比为1∶6,所述B组分的组成和质量分数如下:特种水泥份、石英砂份、超细矿粉份,硅灰份,可再分散乳胶粉份,特种纤维份,保水增稠剂份,减水剂份、纳米抗渗剂份。该盾构管片快速修补剂,是一种由硅丙乳液改性的水泥基复合材料,它既保留了无机材料易得、耐久性好、环境友好,价格相对便宜的优点,又发挥了高分子材料高粘结强度和柔韧性的优势,专用于混凝土盾构管片缺损的修补。
