Abstract

In this study, Portland cement (PÇ 42,5) replaced with Crom Magnesit brick dust as a ratio of its weight of %0, %5, %10, %15, %20 and %25. By this prosedure, six different mixture are prepared and effect of cement is investigated on the opening and closing time of the setting. As a result, the mixture %5 Crom Magnesit brick dust decreases the opening and closing setting time in small amount with respect to control cement, but plussing of crom magnesit brick dust in the mixture increases the opening and closing setting time

Özet

Bu çalışmada, portland çimentosunun (PÇ 42,5) ağırlıkça %0, %5, %10, %15, %20 ve %25’i yerine Krom Mağnezit tuğla tozları ikame edilerek altı değişik karışım elde edilmiş ve çimentonun (PÇ42,5) priz başlama ve sonuna olan etkisi araştırılmıştır. Sonuç olarak %5 katkılı Krom Mağnezit tuğla tozunun çimentoda priz başlama ve priz sonu sürelerini kontrol çimentosuna göre nispeten azda olsa kısalttığını ancak miktar arttıkça priz başlama ve priz sonu süresinin uzadığı tespit edilmiştir.
