文摘
- •
Pre-mixed earthen plasters were tested for highlighting any correlation between textural and/or compositional characteristic and their performances.
- •
The presence of natural additives (straw particles/fibres) seems to increase open porosity and pore interconnection.
- •
Abundance of clay minerals seems to improve the aptitude of the earthen plaster to control moisture adsorption and desorption.
- •
Sound absorption performances seem to be correlated to open porosity and abundance of sand aggregate.
- •
Macropore (> 0.05 μm) volume plays a considerable role in thermal conductivity performance.
