“…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.…”

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).

“…Therefore the wood material impregnated with some chemical substances when it used in outdoor environments [4,5]. Because of degradation in the outdoor exposure is slow and variable, it requires that the changes be examined under the same conditions for a given period [6]. Stamm, (1978) found that lignin was degraded and decayed in wood remaining for 20 years under outdoor conditions without impregnation and oversurface treatment, and that cellulose was little affected except for the nearby parts [7].…”

The most objectionable environment for wood is outdoor conditions. In this study, test specimens prepared from chestnut wood (Castanea sativa Mill) were impregnated with natural and chemical impregnation agent. It was aimed to determine the effect of outdoor conditions on physical and mechanical properties of wood material by keeping them under these conditions for one year. As natural impregnation material pine tannin and acorn tannins, as chemical impregnation material imersol aqua and timbercare aqua were used. The retention amount, air-dried density, bending strength, modulus of elasticity, compression strength parallel to fibers, adhesion strength parallel to fibers, screw withdrawal strength were determined. As a result, it can be said that the physical and mechanical test values can compare wood impregnated with natural impregnation materials to wood impregnated with chemical impregnation materials after one year exposed to outdoor conditions. Anahtar Kelimeler: Outdoor conditions, chestnut, pine tannin, acorn tannin, mechanical tests. Açık Koşullarına Bırakılan Doğal ve Kimyasal Maddelerle Emprenye Edilen Kestane Odununun BazıFiziksel ve Mekanik Özellikleri ÖZ Ahşap koruyucular, ahşabın kullanım ömrünü uzatmak için yaygın şekilde kullanılmaktadır. Ağaç için en sakıncalı ortam açık hava koşullarıdır. Bu çalışmada, kestane (Castanea sativa Mill) ağacından hazırlanan örnekler doğal ve kimyasal emprenye maddesi ile emprenye edilmiştir. Açık hava koşullarının ağaç malzemenin fiziksel ve mekanik özelliklerine etkisini, bir yıl boyunca bu koşullar altında tutarak belirlenmesi amaçlandı. Doğal emprenye materyali olarak çam taneni ve meşe palamudu taneni, kimyasal emprenye maddesi olarak imersol aqua ve timbercare aqua kullanılmıştır. Retensiyon miktarı, hava kurusu yoğunluk, eğilme direnci, elastikiyet modülü, liflere paralel basınç direnci, liflere paralel yönde yapışma direnci, vida tutma direnci belirlenmiştir. Sonuç olarak, doğal emprenye maddeleriyle emprenye edilen ahşap malzemelerin kimyasal emprenye maddeleri ile emprenye edilen ahşap malzemeler ile bir yıl süreyle açık hava koşulları altındaki değerlerin mukayese edilebilir düzeyde olduğu söylenebilir.

“…Depending on the variations in the WWU composition, the energy characteristics may vary. The presence of waterproofing materials and some types of glue, i.e., can facilitate combustion, increasing the temperature and emissions of gases, such as CO 2 , CO, SO 2 , and NO, during the process (FIDAN et al, 2016).…”

This research analyzed the effect of the addition of E. grandis x E. urophylla wood to the wood waste of urban origin (WWU) as a strategy for energy generation. The WWU was collected in transshipment and from a sorting company of civil construction waste in the city of Piracicaba, SP. The wood of eucalyptus was obtained from a 7-year old plantation. Five treatments with proportions (%) of WWU and eucalyptus wood were analyzed: T1 = 100/0, T2 = 75/25, T3 = 50/50, T4 = 25/75 and T5 = 0/100. The treatments had the physical, chemical, immediate characteristics, mineral contaminants rate, and combustion test (ICOM) analyzed. The data were analyzed through the study of variance, correlations, and multivariate hierarchical clusters analysis (HCA). The higher content of extractives, holocellulose, volatile materials, low ash content values, rate of mineral contaminants and high performance for combustion test were observed only for the treatment having exclusively eucalyptus wood (T5). However, the addition of eucalyptus wood in the WWU allowed for the increase of the ICOM of these materials. In this way, the T3 treatment presents as the most recommended for energetic use.
