Submarine pipeline counterweight concrete repairing material and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to a submarine pipeline counterweight concrete repairing material and a preparation method thereof. The submarine pipeline counterweight concrete repairing and repairing material is prepared from a cementing material, aggregate, a polymer, a defoaming agent, a water-retaining agent, a thixotropic agent, a water reducing agent, a retarder, pigment and the like. The submarine pipeline counterweight concrete repairing and repairing material has the advantages of excellent physical and mechanical properties and durability, excellent construction performance, controllable and adjustable operable time and appearance color, high density, low water absorption rate, fast development of early strength, high later strength, fast development of bonding strength, high bonding strength, no shrinkage cracking problem, good durability, and long service life. Especially, the seawater corrosion resistance is excellent, and the like.
本发明属建筑材料技术领域，具体涉及一种海底管道配重混凝土修复修补材料及其制备方法。本发明所述的海底管道配重混凝土修复修补材料由胶凝材料、骨料、聚合物、消泡剂、保水剂、触变剂、减水剂、缓凝剂、颜料等组成。本发明所述的海底管道配重混凝土修复修补材料，具有优良的物理力学性能和耐久性能，施工性能优异，可操作时间及外观颜色可控可调，密度高、吸水率低，早期强度发展快，后期强度高，粘结强度发展快，粘结强度高，无收缩开裂问题，耐久性好，尤其是耐海水侵蚀性能优异等优点。
