Concrete alkali inhibitor as well as preparation method and application thereof
The invention discloses a concrete alkali inhibitor as well as a preparation method and application thereof, and the concrete alkali inhibitor comprises the following components in parts by weight: 50-70 parts of metakaolin, 35-50 parts of fly ash, 15-25 parts of nano silicon dioxide, 3-10 parts of a silane coupling agent, 5-10 parts of graphene oxide, 5-15 parts of polyurethane resin, 10-20 parts of an expanding agent and 10-25 parts of a water reducing agent. The alkali inhibitor significantly reduces the concrete efflorescence phenomenon. The alkali inhibitor can reduce the content of saltpetering substances in a concrete material, reduce transmission media of the saltpetering substances and block ion channels for transmission of the saltpetering substances in concrete. The alkali inhibitor can significantly improve the saltpetering degree of the concrete surface. The alkali inhibitor for inhibiting concrete efflorescence is excellent in performance and reasonable in formula. The saltpetering resistance of the concrete material is remarkably improved, and the quality, the mechanical property and the durability of the concrete material are remarkably improved.
本发明公开一种混凝土抑碱剂及其制备方法和应用，该混凝土抑碱剂按照重量份数计，包括50～70份的偏高岭土、35～50份的粉煤灰、15～25份的纳米二氧化硅、3～10份的硅烷偶联剂、5～10份的氧化石墨烯、5～15份的聚氨酯树脂，10～20份的膨胀剂以及10～25份的减水剂。该抑碱剂显著减少了混凝土泛碱现象。该抑碱剂可降低混凝土材料内的泛碱物质含量、减少泛碱物质的传输介质和堵塞混凝土中泛碱物质传输的离子通道。该抑碱剂可显著改善混凝土表面的泛碱程度。本发明的抑制混凝土泛碱的抑碱剂性能优异，配方合理。不仅显著提高混凝土材料的抗泛碱性能，而且对于混凝土材料的质量、力学性能和耐久性都产生了显著的改善结果。
