ALÇI ESASLI KARIŞIMLARDA MİKRONİZE CAM KÜRECİKLERİNİN DEĞERLENDİRİLMESİ

Öz

Bu çalışmada mikronize cam küreciklerinin alçı esaslı karışımların mühendislik özelliklerine etkileri incelenmiştir. Bu kapsamda mikronize cam kürecikleri alçı yerine ağırlıkça %10, %20 ve %30 oranında kullanılmıştır. 40x40x160 mm boyutunda prizmatik örnekler üretilerek, üretilen örneklerin sertleşmiş birim hacim ağırlık, ultrasonik ses geçiş hızı, su emme, kılcal su emme ve görünen porozite değerleri ölçülmüştür. Aynı zamanda 140x160x20 mm boyutlarına sahip örnekler üretilerek hazırlanan alçı esaslı karışımların ısıl iletim katsayıları ölçülmüştür. Mekanik özellikler kapsamında tek eksenli basınç dayanımı ve üç noktalı eğilme dayanımı testleri uygulanmıştır. Alçı esaslı karışımlarda mikronize cam küreciklerinin kullanımı birim hacim ağırlığı değerlerini yükseltmiştir. Ultrasonik ses geçiş hızı değerleri ise düşmüştür. Görünür porozite değeri de cam küreciklerinin kullanımı ile azalmıştır. Buna bağlı olarak su emme ve kılcal su emme değerlerinde de azalmalar gözlenmiştir. Isıl iletim katsayısı değerleri cam küreciklerin kullanımı ile referans alçı örneğinden daha iyi sonuçlar vermiştir. Cam kürecik kullanımı alçı esaslı karışımların mekanik özelliklerinde de bir miktar düşüşe neden olmuştur. Ancak bu azalmanın çok ciddi düzeylerde olmadığı gözlemlenmiştir. Elde edilen sonuçlar alçı esaslı karışımlarda mikronize cam küreciklerinin değerlendirilmesiyle su emme direnci daha yüksek, kabul edilebilir mekanik özelliklere sahip ve ısı yalıtım özellikleri geliştirilmiş yeni alçı esaslı ürünler üretilebileceğini göstermektedir.

EVALUATION OF GLASS MICROSPHERES IN GYPSUM-BASED MIXTURES

Abstract

In this study, the effects of glass microspheres on the engineering properties of gypsum-based mixtures were investigated. In this context, glass microspheres were used at the rate of 10%, 20%, and 30% by weight instead of gypsum. By producing 40x40x160 mm prismatic samples, the hardened unit weight, ultrasonic pulse velocity, water absorption, capillary water absorption, and apparent porosity values of the produced samples were measured. At the same time, the thermal conductivity coefficients of the gypsum-based mixtures were measured by producing samples with dimensions of 140x160x20 mm. Within the scope of mechanical properties, uniaxial compressive strength and three-point bending strength tests were applied. The use of glass microspheres in gypsum-based mixtures increased the unit volume weight values. On the other hand, ultrasonic pulse velocity values decreased. The apparent porosity value was also reduced with the use of glass microspheres. Accordingly, decreases were observed in water absorption and capillary water absorption values. The thermal conductivity coefficient values gave better results with the use of glass microspheres than the reference plaster sample. The use of glass microspheres also caused a slight decrease in the mechanical properties of gypsum-based mixtures. However, it has been observed that this decrease is not very significant. The results show that by evaluating glass microspheres in gypsum-based mixtures, new gypsum-based products with higher water absorption resistance, acceptable mechanical properties, and improved thermal insulation properties can be produced.
