Technical Feasibility of Limewash for the Conservation of the External Walls of Historic Buildings:Exemplified by Fortaleza do Monte in Macao
摘要
Abstract
Fortaleza do Monte(Mount For-tress),one of the important historic buildings in the Historic Centre of Macao,retains limewash residues on three sides of its rammed earth exte-rior walls.However,the technical feasibility of using limewash as a protective material for the weathered plaster layer and the rammed earthen surface layer remains uncertain,partly because its technical advantages have yet to be fully demonstrated.This study evaluates the protec-tive effects of limewash on the surfaces of lime plaster and adobe bricks through experiments.It finds that limewash can effectively penetrate and fill microcracks and void on the weathered lime plaster surface,reducing the water absorption rate of the adobe brick surface and maintaining stability under water erosion.The active infrared thermographic analysis of sample surfaces with and without limewash treatment shows that limewash can effectively prevent rapid heat ab-sorption of the weathered lime plaster layer and adobe brick surface,thus preventing thermal deformation.On-site tests further indicates that under subtropical maritime climate conditions,the limewash coating can last for at least four years.The findings proves that limewash can serve as a protective material for weathered lime plaster layer and rammed earth surface layer.关键词
