Submarine pipeline counterweight concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to submarine pipeline counterweight concrete and a preparation method thereof. The submarine pipeline counterweight concrete is prepared from Portland cement, a composite admixture, aggregate, a thixotropic agent, a water reducing agent and water. The submarine pipeline counterweight concrete disclosed by the invention has the advantages of excellent physical and mechanical properties and durability, high density, low water absorption rate, fast development of early strength, high later strength, easiness in spraying on submarine pipeline matrixes with different sizes, good impact resistance, no shrinkage cracking problem, good durability, especially excellent seawater corrosion resistance and the like. The method is suitable for counterweight application of submarine pipelines and counterweight application of other pipelines, high-quality counterweight can be ensured, the long-term service performance is excellent, and the engineering quality of counterweight concrete pipelines is ensured.
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及其制备方法。一种海底管道配重混凝土由硅酸盐水泥、复合掺合料、骨料、触变剂、减水剂和水组成。本发明所述的海底管道配重混凝土，具有优良的物理力学性能和耐久性能，密度高、吸水率低，早期强度发展快，后期强度高，易于喷涂在不同尺寸海底管道基体，抗冲击性能好，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。本发明适用于海底管道的配重应用，也适用于其他管道的配重应用，能确保高质量配重，且长期服役性能优异，确保配重混凝土管道工程质量。
