Preparation method of natural brucite fiber modified lime-metakaolin composite mortar
The invention discloses a preparation method of natural brucite fiber modified lime-metakaolin composite mortar. The preparation method specifically comprises natural brucite fiber pretreatment and natural brucite fiber modified L-MK mortar, a lime-metakaolin cementing material is an inorganic cementing material having hydraulicity and prepared by mixing slaked lime and active metakaolin accordingto a certain ratio; the metakaolin is a main active component in the L-MK cementing material; therefore, the L-MK cementing material not only retains good compatibility of lime and an ancient building matrix, but also has hydraulicity of cement; the L-MK cementing material has the non-negligible advantage in the repairing work of masonry and rock soil ancient buildings; in addition, the raw materials limestone and kaolin are rich in resource, convenient to process, low in price and low in calcination temperature, CO2 in the atmospheric environment can be absorbed in the hardening process, andthus the L-MK cementing material is a low-energy-consumption environment-friendly material.
本发明公开了一种天然水镁石纤维改性石灰‑偏高岭土复合砂浆的制备方法，具体包括天然水镁石纤维预处理和天然水镁石纤维改性L‑MK砂浆，石灰‑偏高岭土胶凝材料是将熟石灰与活性偏高岭土按一定比例混合后制成的具有水硬性的无机胶凝材料，其中偏高岭土是L‑MK胶凝材料中的主要活性成分，因此，L‑MK胶凝材料既保留了石灰与古建筑基体良好兼容性的同时又具有水泥的水硬性，在砖石及岩土质古建筑的修护工作中具有不可忽略的优势，此外，其原料石灰石与高岭土资源丰富、加工便利、价格低廉，煅烧温度低，硬化过程中还会吸收大气环境中的CO2，因而L‑MK胶凝材料还是一种低能耗的环境友好型材料。
