Abstract

Bu çalışmada, kızılçam lifleri ve ticari çimento kullanılarak laboratuar şartlarında üretilmiş çimentolu lif levhaların hızlandırılmış yaşlandırma testleri öncesi ve sonrasında bazı fiziksel ve mekanik özellikleri araştırılmıştır. Levhalar üzerinde ayrıca yoğunluğun, lif/çimento oranının ve kullanılan kimyasal oranının etkisi de incelenmiştir. Çalışma sonuçlarına göre hızlandırılmış yaşlandırma testleri fiziksel ve mekanik özellikleri azaltıcı etki yapmaktadır. Yoğunluğun ve kullanılan bağlayıcı oranının artırılması mekanik özellikleri genellikle önemli düzeyde arttırmaktadır. Lif/çimento oranının artması eğilme direnci, kalınlığına şişme ve su alma değerlerini önemli oranda arttırırken elastikiyet modülünü önemli ölçüde düşürmüştür. Çalışma sonuçlarına göre kızılçam lifleri kullanılarak üretilen çimentolu lif levhalar dış ortamda kullanılmaya elverişlidir.
Anahtar Kelimeler: Çimentolu lif levha, yaşlandırma testleri, fiziksel ve mekanik özellikler

SOME PHYSICAL AND MECHANICAL PROPERTIES OF CEMENT BONDED FIBERBOARD EXPOSED TO ACCELERATED AGING

Abstract

In this study, some mechanical and physical properties before and after accelerated aging tests of the cement bonded fiberboard made of using Calabrian pine fibers have been investigated. Effects of density, wood / cement ratio, and accelerator (%) used in manufacturing experimental boards have been also studied. Comprehensive sets of replicated physical and flexural test data were generated, and were analyzed statistically. The results obtained in this study were indicative of significant effects of accelerated aging on physical and flexural performance of cement bonded fiberboard. Increase of density and percent of accelerators used generally causes an increase in mechanical properties. Percent accelerator used also cause an increase in TS and WA. Increase of fiber / cement ratio resulted in an increase in MOR, TS, and WA while a significant decrease was observed for modulus of elasticity. Results indicate that fiber cement boards with Calabrian pine fibers are suitable for outdoor exposure conditions.
Keywords: Cement bonded fiberboard, physical and mechanical properties, accelerated aging
