Natural hydraulic lime mortar for repairing cultural relics and buildings and modification preparation method of natural hydraulic lime mortar
The invention relates to the field of cultural relic building protection material modification research, in particular to natural hydraulic lime mortar for cultural relic building repair and a modification preparation method thereof. The mortar is prepared from 15 wt% of silica fume instead of natural hydraulic lime (NHL2), 1% of additive glutinous rice slurry and 1.5% of paper strip fiber. The mortar prepared according to the method has good air permeability and high compatibility with a cultural relic building repair matrix. The silica fume has high pozzolanic activity and reacts with the natural hydraulic lime, the mechanical strength of the mortar is greatly improved, meanwhile, the use cost can be reduced, environmental pollution can be reduced, the water absorption rate is reduced through the preparation method, the durability of the mortar is greatly improved, and the mortar better plays a role in cultural relic building repair.
本发明涉及文物建筑保护材料改性研究领域,尤其涉及一种文物建筑修复用天然水硬性石灰砂浆及其改性制备方法。采用硅灰以15wt%代替天然水硬性石灰(NHL2),添加剂糯米浆浓度为1%和纸筋纤维的掺量为1.5%制备砂浆。依据上述方法制备的砂浆具有透气性好,与文物建筑修复基体相容性高。硅灰具有较强的火山灰活性与天然水硬性石灰发生反应,大幅提高了砂浆的力学强度,同时还能降低使用成本和减少环境的污染,并且上述制备方法降低吸水率并大幅提高砂浆的耐久性,使砂浆在文物建筑修复中更好的发挥作用。
