High-performance marine concrete with excellent durability and preparation method thereof
The invention discloses high-performance marine concrete with excellent durability and a preparation method thereof. The concrete is prepared from the following components in parts by mass: 384-350 parts of cement, 154 parts of water, 785-797 parts of sand, 100-106 parts of small stones, 901-951 parts of large stones, 15-90 parts of fly ash, 15-50 parts of mineral powder, not higher than 16.4 parts of silica fume, not higher than 27 parts of metakaolin, not higher than 27 parts of microbeads, 5.64-6.9 parts of water reducing agent and 7.1-7.4 parts of a corrosion inhibitor. According to the invention, coarse admixtures such as fly ash, mineral powder and the like and fine admixtures such as silica fume, metakaolin, microbeads and the like are compounded and added, so that the prepared concrete has better density and impermeability; finally, the high-performance marine concrete with excellent durability and high strength is obtained.
本发明公开了一种具有优异耐久性的高性能海工混凝土及其制备方法，该混凝土配合比各成分按质量分数计如下：水泥384‑350份、水154份、砂785‑797份、小石子100‑106份、大石子901‑951份、粉煤灰15‑90份、矿粉15‑50份、硅灰不高于16.4份、偏高岭土不高于27份、微珠不高于27份、减水剂5.64‑6.9份、阻锈剂7.1‑7.4份。本发明通过选择粉煤灰、矿粉等粗掺合料及硅灰、偏高岭土和微珠等精细掺合料进行复合添加，使配制的混凝土具有更好的致密度、抗渗性；最终获得具有优异耐久性，同时具有高强度的高性能海工混凝土。
