The objective of this work was to improve the thermal stability, flame resistance, and surface properties of black poplar (Populus nigra L.) wood via different impregnation methods. The impregnation methods were employed through two distinct modalities: vacuum impregnation and immersion impregnation. Here, poplar wood was impregnated with calcium oxide solutions (1%, 3% and 5%). Fourier-transform infrared spectroscopic analysis revealed a shift in the typical peaks of cellulose, hemicellulose, and lignin depending on the impregnation method and solution ratio. Thermogravimetric analysis and the limiting oxygen index indicated that the samples impregnated with lime solutions exhibited higher thermal stability than the unimpregnated wood. Both impregnation methods caused a decrease in water absorption and thickness swelling of the sample groups. Using a scanning electron microscope, the effect of the impregnation process on the structure of the wood was examined. In terms of surface properties, it was determined that the surface roughness value increased. On the contrary, it was observed that the contact angle value also increased. A significant difference emerged between the applied methods. In conclusion, the applied lime minerals are suitable substances to increase the flame resistance and thermal stability of black poplar wood.

“…Otherwise, pedestrians may be injured once stepping on the damaged timber deck, which has already been reported across the country. In order to understand the mechanical behavior of timber materials, a large extent of experiments have already been carried out including nail withdrawal (Rammer et al, 2001;Taj et al, 2009), compression (Keskin, 2017;Saad et al, 2016;Xu et al, 2021), flexure (Burawska-Kupniewska et al, 2020). At the same time, it is noticed that in the region of Suzhou there is abundant rainfall as well as distinct seasons, i.e.…”

Timber boardwalks are exposed to the rigorous outdoor environments, and timber is a material with very high sensitivity to environmental factors, including temperature, moisture, etc., which may causes cracks in timber structures without the application of any external loads (Ross, 2010). At the same time, biological intrusion, such as fungus, termite, and other insects, etc., is another threat to the safety of timber structures (Ham et

“…For example in a study the compression strengths of impregnated wood with tanalith-E was investigated. The compression strength values were decrease with tanalith-E to control samples [2]. There are many ongoing researches to increase the resistance of wood especially against combustion and the environmental factors in the wood's place of use [3][4][5][6].…”

For this purpose, the samples, which were prepared from sessile oak wood according to ASTM-E 160-50 combustion principles, impregnated with wolmanit-CB (WC) and tanalith-E (T) in accordance with ASTM-D 1413-76 and then synthetic (St) and Water-based (wb) varnishes were applied according to ASTM-D 3023. The combustion test was carried out in 3 stages, combustion with flame (CWF), self-combustion without flame source (CWOF) and ember combustion stage (ECP). It was aimed to determine the combustion temperature values in CWF, CWOF and ECP stage, weight loss, total combustion time and demolition time. As a result, impregnation applications have increased the total combustion time to between 15-18% and reduced the demolition period. The exact opposite results were obtained for the varnish types, the total combustion time was reduced by 19-21% and the demolition time increased by 10-22%. In CWF stage, the highest temperature was obtained in water-based varnished samples (490 °C), the lowest in non-varnished samples (458 °C); in CWOF stage the highest temperature in water-based varnished samples (572 °C), the lowest in synthetic varnished samples (544 °C); and in ECP stage the highest temperature in non-varnished samples (306.5 °C), the lowest in the samples with the synthetic varnished (262.7 °C).
