High-strength and high-impermeability sea sand concrete and preparation method thereof
The invention discloses high-strength and high-impermeability sea sand concrete, which is prepared from the following components in parts by weight: 200 to 300 parts of cement, 300 to 400 parts of basalt aggregate with the particle size of 10 to 30 mm, 200 to 300 parts of desalted sea sand with the particle size of 0.075 to 5 mm, 50 to 80 parts of superfine fly ash, 60 to 90 parts of superfine manganese slag powder, 30 to 50 parts of LDHs mixed liquid and 120 to 140 parts of water. Wherein the LDHs mixed solution comprises ferric nitrate, magnesium nitrate, a silane coupling agent, sodium carbonate and water. The high-strength and high-permeability-resistance sea sand concrete provided by the invention has excellent resistance to corrosion of chloride ions and the like and good fracture resistance and compressive strength, and can effectively resist damage of a marine corrosion environment to a building structure; the method can be widely applied to maritime work environments.
本发明公开了一种高强高抗渗海沙混凝土，按照重量份计，包括200～300份水泥、300～400份粒径为10～30mm的玄武岩骨料、200～300份粒径为0.075～5mm的淡化海砂、50～80份超细粉煤灰、60～90份超细锰渣粉、30～50份LDHs混合液、120～140份水。其中，所述LDHs混合液包括硝酸铁、硝酸镁、硅烷偶联剂、碳酸钠、水。本发明提供的高强高抗渗海沙混凝土具有优异的抗氯离子等侵蚀能力以及良好的抗折和抗压强度，可有效抵御海洋侵蚀环境对建筑结构的破坏；可以广泛应用于海工环境的应用。
