The effect of the obsidian of the rize region on the hydrating heat of cement

Öz

In this study, the effect of obsidian of Rize region on the hydration heat of cement was investigated. It was compared with the effects of fly ash and blast furnace slag on the hydration heat in cement. The compressive strengths of obsidian, fly ash and blast furnace slag cements were measured.

As a result of this study, the obsidian of Rize decreases the hydration temperature of cement and does not cause a negative effect in terms of compressive strength. Obsidian shows similar effects with respect to fly ash and blast furnace slag in terms of heat and compressive strength of hydration in cement..

Rize yöresi obsidyeninin çimentonun hidratasyon ısısına etkisi

Öz

Bu çalışmada, Rize yöresi obsidyeninin çimentonun hidratasyon ısısını nasıl etkilediği araştırıldı. Çimentoda yaygın olarak kullanılan mineral katkılardan uçucu kül ve yüksek fırın cürufunun çimentodaki hidratasyon ısısına etkileri ile karşılaştırıldı. Obsidyen, uçucu kül ve yüksek fırın cüruflu çimentoların basınç dayanımları ölçüldü.

Çalışma sonucunda Rize yöresi obsidyeninin çimentonun hidratasyon ısısını düşürdüğü görüldü. Basınç dayanımı açısından çimentoda puzolan olarak kullanılabileceği tespit edildi.
