Abstract

The aim of this study is to produce self-compacting mortar with calcium aluminate cement. The advantages of self-compacting mortars like filling and passing ability without the need of vibration process and the superior properties of calcium aluminate cement like abrasion resistance, high thermal resistance, high acid resistance, and high early strength are intended to be combined. However, hydration process of calcium aluminate cement might cause strength reduction at later ages. Therefore, in order to prevent the possibility of strength reduction, several supplementary binders such as gypsum, fly ash, ground granulated blast furnace slag and silica fume were utilized in the mortar mixtures. In this sense, 11 different self-compacting mortars were produced, and those mortars were tested to obtain values of mini slump flow, setting time, abrasion resistance and 1, 2, 7, 28, and 90 day flexural and compressive strength. Test results showed that different supplementary binders exhibited different behaviors in mortar mixtures. As a conclusion, it was seen that the production of self-compacting mortar with calcium aluminate cement was possible.

Özet

Bu çalışmanın amacı, kalsiyum alüminatlı çimento ile kendiliğinden yerleşen harç üretmektir. Kendiliğinden yerleşen harçların vibrasyon işlemine ihtiyaç duymadan doldurma ve geçme kabiliyeti gibi avantajları ile kalsiyum alüminatlı çimentoların aşınma direnci, yüksek ısıl dayanıklılık, yüksek asit direnci, yüksek erken dayanım gibi üstün özelliklerinin birleştirilmesi amaçlanmaktadır. Bununla birlikte, kalsiyum alüminatlı çimentoların hidratasyonu ileriki yaşlarda dayanım kayıplarına yol açabilmektedir. Bu sebeple, dayanım kaybı ihtimalini önlemek amacıyla, alçı, uçucu kül, öğütülmüş granüle yüksek fırın cürufu, silis dumanı gibi ilave bağlayıcı malzemelerden harç karışımlarında yararlanılmıştır. Bu bağlamda, 11 farklı kendiliğinden yerleşen harç üretilmiştir ve bu harçların yayılma, priz süresi, aşınma dirençleri ve 1, 2, 7, 28 ve 90 günlük eğilme ve basınç dayanımları belirlenmiştir. Test sonuçları ilave bağlayıcıların harç karışımlarında farklı davranışlar sergilediğini göstermiştir. Sonuç olarak, kalsiyum alüminatlı çimento ile kendiliğinden yerleşen harç üretiminin mümkün olduğu görülmüştür.
