Abstract

Bu çalışmada inşaat sektörüne yönelik üretimi yapılacak alçılarda, hammadde olan jipsin tane boyutunun ve pişirme sıcaklığının son ürünün performansına etkileri deneysel olarak incelenmiştir. Özellikle, alçıtaşından anhidrit III alçı üretiminin aşamaları detaylandırılmıştır. Analizlerde kullanılan alçıtaşı boyut aralıkları sırasıyla <0.50 mm, 0.50-0.75 mm, 0.75-1 mm, 1-2 mm, 2-4 mm, 4-8 mm, 8-16 mm ve >16 mm’dir. Her bir boyut aralığındaki alçıtaşı örnekleri sıcaklığı önceden sırasıyla 160, 170, 180, 190, 200, 220, 240, 255 ve 270 °C’ye ayarlanmış bir fırında 10’ar dakika krozeler içinde bekletilmiştir. Çalışma sonuçlarına göre, özellikle 0.75-1 mm boyut aralığındaki alçıtaşı örneklerinin anhidrit alçı için dehidratasyon ve kalsinasyon sıcaklık değerinin 200°C olduğu belirlenmiştir. Bu tane boyutu ve sıcaklık ile üretilen anhidrit III ürünü tekrar boyutlandırılmış ve mekanik özellikleri araştırılmıştır. En yüksek basınç dayanımı 500-750 μm olarak boyutlandırılan anhidrit III’te tespit edilmiştir.

Abstract

In this study, the effects of grain size and dehydration temperature of gypsum rock, which is the raw material, on the performance of the final product in gypsum to be produced for the construction industry were investigated experimentally. In particular, the stages of anhydrite III gypsum production from gypsum rock are detailed. The gypsum grain size ranges used in the analyzes are <0.50 mm, 0.50-0.75 mm, 0.75-1 mm, 1-2 mm, 2-4 mm, 4-8 mm, 8-16 mm and >16 mm, respectively. Gypsum samples in each grain size range were kept in crucibles for 10 minutes in an oven whose temperature was previously set to 160, 170, 180, 190, 200, 220, 240, 255 and 270°C, respectively. According to the results of the study, it was determined that the grain size and dehydration temperature values for anhydrite gypsum of gypsum rock samples, especially in the 0.75-1 mm size range, were 200°C. The anhydrite III product produced with this grain size and temperature was resized and its mechanical properties were investigated. The highest compressive strength was found in anhydrite III with grain size of 500-750 μm.
