Effect of colloidal silica nanoparticles produced from rice husk on dimensional stability and water absorption of poplar wood (Populus deltoides)

This research was conducted to determine the physical properties of poplar wood treated with silica colloidal nanoparticles prepared from rice husk using ash making and alkaline digestion. Test samples were prepared according to ASTM-D1037 standard with the dimension of 2×2×2 cm and then were impreg...
