Abstract
Research on the effect of elevated temperature on the resistance to bending spruce wood impregnated with silica containing fire retardant. The paper presents results of the study on the effect of high temperature on the resistance to bending spruce wood impregnated with aqueous solution containing SiO2 nanoparticles at a concentration of 400 ppm. Impregnation was carried out with the vacuum method of vacuum pressure of 0.07 MPa. Based on the results of the studies, it should be noted that impregnation with aqueous solution containing SiO2 nanoparticles adversely affects the spruce wood resistance to bending both at room temperature and after initial exposure at 230 °C. The results of the tests conducted at 230° C show that impregnation has unfavourable effect on sampling stiffness. There is an increase in the statistical coefficient of variation in elevated temperature conditions.
