Abstract
Beton, çimento esaslı kompozit bir yapı malzemesidir. Çimentonun hidratasyon süreci ve ürünleri doğrudan beton özelliklerini etkilemektedir. Bu amaçla, istenilen beton kalitesini gerçekleştirmek maksadıyla kür işlemleri uygulanmaktadır. Genellikle beton malzemeye, laboratuvar şartlarında su tankı içerisinde bekletilerek dayanım kazandırılmaktadır. Bu çalışmada mineral katkı ikameli betonlara, farklı sıcaklık (110-145-165 0C) ve basınç (2-4-6 bar) değerlerinde basınçlı buhar kürü uygulanmıştır. Kür işlemlerinin ardından fiziksel ve mekanik deneyler gerçekleştirilmiştir. Elde edilen sonuçlara göre, basınçlı buhar kürü mineral katkılı betonların dayanımında düşüşe sebep olurken en iyi mekanik değerler 145 0C sıcaklık ve 4 bar buhar
basıncı altında kür edilen numunelerde tespit edilmiştir.

Abstract
Concrete is a cement based composite building material. Cement's hydration process and products directly affect the concrete properties. For this purpose, curing operations are carried out in order to realize the desired concrete quality. Generally, concrete material is retained in water tank under laboratory conditions and it is given strength. In this study, pressurized steam curing was applied to concrete with mineral admixtures at different temperatures (110-145-165 0C) and pressure (2-4-6 bar) values. After curing, physical and mechanical tests were carried out. According to the results obtained, the best mechanical values were determined at the samples cured under 145 0C temperature and 4 bar vapor pressure, while the pressure steam cure caused a decrease in the strength of the mineral added concretes.
