Comparison of resistance improvement to fungal growth on green and conventional building materials by nano-metal impregnation

摘要

This study is aimed for comparing the biological resistance of green and conventional building materials (BMs) before and after nano-metal treatment, as well as exploring best nano-metals to improve fungal growth resistance of BMs. The selected BMs include wooden flooring (WF), green wooden flooring (GWF), gypsum board (GB), green gypsum board (GGB), calcium silicate board (CSB), green calcium silicate board (GCSB), mineral fiber ceiling (MFC) and green mineral fiber ceiling (GMFC). The Aspergillus brasiliensis or Penicillium funiculosum was inoculated on each sample and their growth was visually evaluated according to ASTM G21-09.
