Low-carbon high-strength corrosion-resistant pipe pile and preparation method thereof
The invention belongs to the technical field of constructional engineering, and relates to a low-carbon high-strength corrosion-resistant pipe pile and a preparation method thereof. The technical key points are as follows: the concrete admixture comprises the following components in parts by mass: 5.5-6.5 parts of a composite admixture; 0.05 to 0.2 part of an anti-corrosion inhibitor; 13 to 15 parts of cement; 25 to 30 parts of machine-made sand; 50 to 55 parts of broken stone; 0.1 to 0.3 part of a high-performance water reducing agent; and 4-6 parts of water. The low-carbon high-strength corrosion-resistant concrete is prepared by replacing cement with the composite admixture, the strength grade of the high-strength concrete is C100, the cement consumption of the high-strength concrete is remarkably reduced, autoclaving is avoided in the forming process, the corrosion resistance of the machine-made sand high-strength concrete is improved, and the purposes of low carbon, high strength and corrosion resistance are achieved. And the high-strength concrete is prepared by reducing the use amount of cement, so that remarkable economic benefits and environmental benefits are realized.
本发明属于建筑工程技术领域，涉及一种低碳高强耐腐蚀管桩及其制备方法。其技术要点如下：包括如下质量份的各组分：复合掺合料5.5~6.5份；防腐蚀抑制剂0.05~0.2份；水泥13~15份；机制砂25~30份；碎石50~55份；高性能减水剂0.1~0.3份；水4~6份。本发明通过使用复合掺合料取代水泥，制备出满足低碳高强耐腐蚀的混凝土，高强混凝土的强度等级为C100，显著降低高强混凝土的水泥的用量，在成型过程中免压蒸，提高机制砂高强混凝土的耐腐蚀性，达到低碳高强耐腐蚀的目的，并减少水泥的用量制备高强混凝土，实现显著的经济效益和环境效益。
