摘要/Abstract

摘要： 水硬性石灰因优异的性能且与文物亲和力较强而被广泛用于历史建筑、岩土文物修复工作中。本文介绍了水硬性石灰的制备与性质,并对酸、碱、盐三类侵蚀环境下水硬性石灰宏观性能变化、改性后的性能提升及微观劣化机理进行了总结,旨在揭示水硬性石灰腐蚀行为的机理。研究表明,盐环境对水硬性石灰造成的损坏最严重,酸性环境次之,碱性环境最小。可以通过降低水胶比、加入火山灰材料和掺入改性剂来改善水硬性石灰生成物、孔隙率和微观形貌,以提高水硬性石灰的耐久性。最后指出水硬性石灰现阶段研究的不足,为水硬性石灰应对实际环境问题及新型建筑修复材料的研发提供参考与启示。

Abstract: Hydraulic lime is widely used in the restoration of historical buildings and geotechnical heritages due to its excellent performance and strong affinity with cultural relics. This paper introduces the preparation and properties of hydraulic lime, and summarizes the macroscopic performance changes of hydraulic lime in three types of corrosive environments: acid, alkali and salt, the performance improvement after modification and the microscopic deterioration mechanism, aiming to reveal the mechanism of the corrosion behavior of hydraulic lime. The research shows that salt environments cause the most damage to hydraulic lime; acid environments are second; and alkaline environments are the least. The durability of hydraulic lime can be improved by lowering the water cement ratio, adding volcanic ash materials and incorporating modifiers to improve the hydraulic lime generators, porosity and micro-morphology. Finally, the deficiencies of the research on hydraulic lime at this stage are pointed out, which provides reference and enlightenment for the research and development of hydraulic lime to deal with the actual environmental problems and new building repair materials.
