基于原真性的近代历史建筑混凝土材料清洗原则及方法

Research on cleaning principles and methods of early-modern historic architecture concrete based on the authenticity

以"原真性"为指导原则和评价标准的历史建筑保护与修复工作已成为国际上该领域的重要议题,具体实施的技术问题更是近年来探索之热点。清洗,作为历史建筑保护与修复技术链条的初始环节,不仅有益于保持建筑的原始风貌,更是后续修复工作的必要基础。以我国近代历史建筑主要材料——混凝土为对象,提出具体的清洗原则,根据其劣化现象有针对性地提出清洗方法,为近代历史建筑混凝土材料的保护修复工作提供技术指导与支持,为专业的、科学的"原真性"保护提供技术基础。

The preservation and restoration of early-modem historic architecture based on the authenticity has become an important topic in the field.Cleaning, as the initial link of the technology chain in historical architecture preservation and restoration, not only con- ducive to maintaining the authenticity of the architecture, also is the necessary basis for the follow-up work.Take concrete materials in Chinese early-modem historic architecture as the object,put forward specific cleaning principles, according to deterioration put forward targeted cleaning method for the concrete materials, to provide guidance and support for the professional, scientific authenticity preserva- tion and restoration.
