Crack-resistant and corrosion-resistant concrete suitable for marine environment and preparation method of crack-resistant and corrosion-resistant concrete
The invention relates to anti-crack and corrosion-resistant concrete suitable for a marine environment and a preparation method of the anti-crack and corrosion-resistant concrete. Comprising the following components in parts by mass: 300 to 310 parts of cement, 30 to 40 parts of fly ash, 20 to 30 parts of mineral powder, 10 to 15 parts of silica fume, 770 to 790 parts of fine aggregate, 900 to 950 parts of coarse aggregate, 8 to 10 parts of a water reducing agent, 130 to 135 parts of mixing water, 15 to 18 parts of heavy calcium carbonate, 12 to 17 parts of a composite anti-cracking agent and 0.6 to 0.8 part of polypropylene fiber. The composite anti-cracking agent is formed by optimally matching multiple active chemical substances, the anti-cracking performance, mechanical performance and durability of concrete can be effectively improved for a long time, the performance of the concrete can be further enhanced through the synergistic effect of the composite anti-cracking agent, the mineral admixture and the polypropylene fibers, meanwhile, the concrete is endowed with the crack self-repairing capacity, and the self-repairing effect is good. The service life of the concrete structure is effectively prolonged.
本发明是一种适用于海洋环境的抗裂耐腐蚀混凝土及其制备方法，抗裂耐腐蚀混凝土，包括以下质量份数的组分：水泥300‑310份、粉煤灰30‑40份、矿粉20‑30份、微硅粉10‑15份、细骨料770‑790份、粗骨料900‑950份、减水剂8‑10份、拌合水130‑135份、重质碳酸钙15‑18份、复合抗裂剂12‑17份、聚丙烯纤维0.6‑0.8份。本发明通过优化搭配多种活性化学物质形成复合抗裂剂，可长久有效提升混凝土的抗裂性能、力学性能和耐久性能，与矿物掺和料和聚丙烯纤维的协同作用能进一步增强混凝土性能，同时赋予混凝土裂缝自修复能力，有效延长混凝土结构使用寿命。
