Study on the potential use of nano-wollastonite to improve the fire resistance and dimensional stability of poplar wood (Populus nigra)
In this study possibility of nano-wollastonite uses for improving fire retardency of poplar wood (Populus nigra) was investigated. Also, water absorption and volumetric swelling of specimens were measured. Specimens for fire resistance were prepared according to ISO 11925 standard and for physical p...
