Characterization of the Combustion Parameters of Impregnated and Varnished Cedar Wood (Cedrus libani)

Abstract

The present study investigated the effect of various types of impregnating and surface treatment materials on the fire resistance of wood material indoors and outdoors. Wood samples (Cedrus libani A. Rich.) were impregnated with Wolmanit-CB or Tanalith-E according to ASTM D1413‐76 (American Society for Testing and Materials 1976). The impregnated surface was treated with either synthetic or water-based outdoor varnish materials. The impregnated and varnished samples were left in outdoor conditions for 1 year. The combustion characteristics of the samples were investigated at the end of 1 year according to the combustion parameters detailed in the ASTM E160‐50 (1975) combustion test. The results of this study indicated that the combustion parameters were lower in the 1-year-old samples (89.12% of control values), in the samples impregnated using Wolmanit-CB (89.18% of control values), and in samples treated using water-based varnish (88.43% of control values). The analysis of flue gas indicated that the O2 content of the 1-year-old samples impregnated with Wolmanit-CB and treated with synthetic varnish was higher, whereas the CO content was lower. In conclusion, impregnated Wolmanit-CB specimens provide higher fire resistance.

The Effects of Wood Preservatives on the Combustion Characteristics of Sessile Oak (Quercus Petreae L.)

“…In future studies; wood preservatives can be tested on samples in different sizes by applying different concentrations and pressures. The varnish types reduced the total time of combustion between 19-21% and raised the demolition time between 10-22% [3][4][5][6]38]. Wolmanit-CB raised the average temperature values in combustion with flame and combustion without flame, kept the minimum combustion temperatures high.…”

“…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]. Water-based solutions prepared from water-borne salt like oil-based creosote, petrol solution *Sorumlu Yazar (Corresponding Author) e-posta : ssyasar@gumushane.edu.tr pentachlorophenol and CCA, ACQ, CCB, CCP and CBA are commonly used wood preservatives [7].…”

Combustion Properties of Impregnated and Heat-Treated Wood Material

“…As a results of study boron compounds showed a decreasing impact on combustion properties of the laminated wood materials. In a similar study Fidan et al [8] investigated the effect of impregnation materials and synthetic or water-based varnish on the combustion properties of wood (Cedrus libani A. Rich.)…”
