为了满足施工现场的要求，自密实混凝土主要是在满足混凝土强度和流动性的前提下，找出如何降低水灰比来控制收缩裂缝的发生，从而达到混凝土“高流动性”和“高稳定性”的平衡。由于自密实混凝土可以提高混凝土的施工性能，降低人工成本，有利于环境保护，同时可以提高硬化混凝土的力学性能和耐久性。为了提高海工混凝土结构的耐久性，在码头和跨海大桥中采用海工高性能混凝土，以提高混凝土结构的使用寿命。在分析自密实混凝土应用意义的基础上，探讨了海洋气候环境下自密实混凝土的设计要点，并对工程中自密实混凝土的工作性能和力学性能进行了分析。
In order to meet the requirements of the construction site, self-compacting concrete is mainly to find out how to reduce the water cement ratio to control the occurrence of shrinkage cracks on the premise of meeting the strength and fluidity of concrete, so as to achieve the balance between "high fluidity" and "high stability" of concrete. As self-compacting concrete can improve the construction performance of concrete and reduce labor costs, it is conducive to environmental protection, and at the same time it can improve the mechanical properties and durability of hardened concrete. In order to improve the durability of concrete structure of marine engineering, high performance concrete of marine engineering is used in the wharf and cross Sea Bridge to improve the service life of concrete structure. Based on the analysis of the application significance of self compacting concrete, this paper discusses the design key points of self compacting concrete in the marine climate environment, and analyzes the working and mechanical properties of self compacting concrete in the project.
