Effect of additive added to cemented wood composite material on board properties

Öz

Cemented wood composites are among the high strength materials formed by combining the good qualities of cement and the high advantages of wood compared to other traditional materials and it is high moisture and fire resistance, easy to workability, high resistance to fungus and termites.
In the study, composite boards were produced by using 20% of red pine wood timber wastes according to the amount of cement and by adding 2.5%, 5% and 10% active wood carbon as an additive, and the effect of different ratios of activated carbon on the board properties was investigated. The humidity, oven dry density (g/cm3), air dry density (g/cm3), water absorption, thickness swelling, bending strength (N/mm2), modulus of elasticity (N/mm2) and heat transmission coefficient values of the cemented wood composite board were determined. It was determined that as the amount of activated carbon added to the produced boards increased, the amount of moisture, water absorption and thickness swelling increased, and the amount of full dry density and air dry density decreased. While there was no effect on the nail holding resistance from mechanical properties, it increased the screw holding resistance, bending resistance and modulus of elasticity values. In addition, it was determined that the additive decreased the heat transfer coefficient value.

Çimentolu odun kompozit malzemeye eklenen katkı maddesinin levha özelliklerine etkisi

Öz

Çimentolu odun kompozitleri, çimentonun iyi niteliklerini ve ahşabın yüksek avantajlarını birleştirerek rutubet ve yangın direnci yüksek, işlenebilmesi kolay, mantar ve termitlere karşı yüksek mukavemet özellikleri göstermesi nedeniyle, lignoselülozik katkılı levhalar içerisinde yüksek dayanımlı malzemeler arasında önemli yapmaktadır.
Yapılan çalışmada, kızılçam (Pinus brutia Ten.) odunu kereste atıkları çimento miktarına göre %20 oranında kullanılarak ve katkı maddesi olarak %2.5, %5 ve %10 oranında aktif odun karbon eklenerek kompozit levhalar üretilmiş ve farklı oranlardaki aktif karbonun levha özellikleri üzerine etkisi araştırılmıştır. Çimentolu odun kompozit levhalarının rutubet; tam kuru yoğunluk (g/cm3), hava kuru yoğunluk (g/cm3), su alma, kalınlık artımı, eğilme direnci (N/mm2), elastikiyet modülü(N/mm2) ve ısı iletim katsayısı değerleri belirlenmiştir. Üretilen levhalar içerisine eklenen aktif karbon miktarı arttıkça, rutubet, su alma ve kalınlık artımı miktarının arttığı, tam kuru yoğunluk ve hava kuru yoğunluk miktarının azaldığı tespit edilmiştir. Mekanik özelliklerden çivi tutma direnci üzerine herhangi bir etkisi görülmezken, vida tutma direnci, eğilme direnci ve elastikiyet modülü değerlerini arttırmıştır. Ayrıca katkı maddesinin ısı iletim katsayısı değerini düşürdüğü tespit edilmiştir.
