Choice of appropriate repair materials for heritage earthen buildings.

本项目旨在研究最适合文物夯土及/或土坯建筑的修复材料。以往的研究表明，土质修复材料的岩土力学性能与现有结构的岩土力学性能相匹配，可以提高修复的性能。在回顾当前的修复技术之后，将调查这种匹配的精度如何影响修复性能（例如强度和耐久性），目的是提出首选修复方法和材料混合的建议。

This project aims to investigate the repair materials best suited for conservation use in heritage rammed earth and/or adobe earthen buildings. Previous research has indicated that matching the geotechnical properties of earthen repair materials with that of the existing structure could improve the performance of the repair. A review of current repair techniques will be followed by investigation of how the precision of this match affects repair performance (e.g. strength and durability), with the aim of producing recommendations of preferred repair methods and material mixes.
