Self-repairing modified lime cementing material for repairing ancient building brick masonry and preparation method of self-repairing modified lime cementing material
The invention discloses a self-repairing modified lime cementing material for repairing ancient building brick masonries and a preparation method of the self-repairing modified lime cementing material, and relates to a modified lime cementing material and a preparation method thereof. The invention aims to solve the problem that the weathering resistance of the cementing material in the existing ancient building brick masonry repair is poor. The modified lime cementing material for repairing the ancient building brick masonry is prepared from a lime cementing material, nano silicon dioxide, asbestos fibers and calcium silicate whiskers, wherein the lime cementing material consists of quick lime, superfine powder calcium hydroxide and hydraulic lime. After lime mortar is prepared from the modified lime cementing material and maintained for 28 days, the compressive strength reaches 6-10 MPa, the breaking strength reaches 4-7 MPa, and the modified lime cementing material can be used for repairing ancient building brick masonries in subfrigid zones and frigid zones.
一种用于古建筑砖砌体修缮的自修复型改性石灰胶凝材料及其制备方法，它涉及改性石灰胶凝材料及其制备方法。本发明是要解决现有的古建筑砖砌体修复中胶凝材料的抗风化较差的问题。本发明的用于古建筑砖砌体修复的改性石灰胶凝材料是由石灰胶凝材料、纳米二氧化硅、石棉纤维和硅酸钙晶须组成；其中石灰胶凝材料由生石灰、超细粉氢氧化钙与水硬性石灰组成。将该改性石灰胶凝材料制备成石灰砂浆养护28天后的抗压强度达到6～10MPa，抗折强度达到4～7MPa，可用于亚寒带、寒带地区的古建筑砖砌体的修复。
