High-strength long-life ocean engineering concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to high-strength long-life ocean engineering concrete and a preparation method thereof. The high-strength long-life ocean engineering concrete is prepared from the following components in parts by weight: 200 to 300 parts of Portland cement, 50 to 100 parts of fly ash, 50 to 80 parts of mineral powder, 20 to 50 parts of silicon powder, 1500 to 2000 parts of aggregate, 30 to 40 parts of stainless steel fiber, 5 to 10 parts of synergist, 5 to 10 parts of water reducing agent and 5 to 10 parts of anti-cracking agent, the synergist is prepared from 50 to 60 percent of aromatic polyamide fiber, 15 to 30 percent of zirconium oxide, 5 to 10 percent of anionic surfactant and 20 to 30 percent of water; and the water reducing agent comprises 30-55% of a polycarboxylic acid water reducing agent, 20-30% of lignosulfonate, 5-10% of a film-forming agent and 20-30% of water. The strength and durability of the concrete in the marine environment are improved, and the service life of the concrete in the marine environment is prolonged.
本发明属于混凝土技术领域，具体涉及一种高强度长寿命海洋工程混凝土及其制备方法。所述高强度长寿命海洋工程混凝土，包括以下重量份数的组分：硅酸盐水泥200～300份、粉煤灰50～100份、矿粉50～80份、硅粉20～50份、骨料1500～2000份、不锈钢纤维30～40份、增效剂5～10份、减水剂5～10份、抗裂剂5～10份；增效剂包括芳香聚酰胺纤维50～60％、氧化锆15～30％、阴离子表面活性剂5～10％、水20～30％；减水剂包括聚羧酸减水剂30～55％、木质素磺酸盐20～30％、成膜剂5～10％、水20～30％，提高了混凝土在海洋环境中的强度、耐久性能和使用寿命。
