Effects of Mineral Additive Substitution on the Fresh State and Time-Dependent Hardened State Properties of Calcium Alumina Cement Mortars

Öz

Calcium aluminate cements (CAC) are a candidate alternative binder to provide the requirements of a repair material such as accelerated hardening, good adhesion, compatibility with existing concrete, dimensional stability and corrosion resistance. The absence of water-soluble hydrated lime among the hydration products can also be accepted as an important advantage. However, the transformation reactions that may occur in the phase structure of the CAC depending on the ambient conditions over time may cause a loss of strength in the concrete produced with this cement. In this study, it is aimed to provide solutions to the problems arising from the conversion reactions in the hydration process of CAC, to improve the fresh state properties and to stabilize the strength development in the long term. Consequently, the effects of using CAC blended with different mineral additives (SiO2 and CaSO4) on the mortar consistency, setting time and rheological properties were investigated. In the hardened state, abrasion resistance and time-dependent compressive and flexural strength developments were determined. As a result of the experimental studies, it was concluded that the CAC mortars containing 16% SiO2 and 50% CaSO4 additives can provide improved properties in their fresh state, and they also demonstrate an improvement in strength after 400 days by obtaining stable products during the hydration process without any time-related strength loss.

Mineral Katkı İkamesinin Kalsiyum Alümina Çimentolu Harçların Taze Hal ve Zamana Bağlı Sertleşmiş Hal Özelliklerine Etkileri

Öz

Kalsiyum alüminat çimentoları (KAÇ) bir onarım malzemesinden beklenen; hızlı sertleşme, iyi yapışma, mevcut betonla uyumluluk, boyutsal kararlılık ve korozyon direnci gibi özellikleri sağlamaya aday bir alternatif bağlayıcıdır. Hidratasyon ürünleri arasında suda çözünür kireç olmaması da önemli bir avantaj olarak görülebilir. Ancak KAÇ’ın zaman içerisinde ortam koşullarına bağlı olarak faz yapısında meydana gelebilen dönüşüm reaksiyonları, bu çimento ile üretilen betonlarda dayanım kaybına neden olabilmektedir. Bu çalışmada KAÇ’ın hidratasyon sürecindeki dönüşüm reaksiyonlarından kaynaklanan problemlere çözüm sunmak, taze hal özelliklerini geliştirmek ve uzun dönemde dayanım gelişimini kararlı hale getirmek amaçlanmıştır. Buna bağlı olarak, farklı mineral katkı kaynaklarının (SiO2 ve CaSO4), KAÇ ile birlikte kullanımının harç kıvamı, priz süresi ve reolojik özelliklere etkileri incelenmiştir. Sertleşmiş halde aşınma dayanıklılığı ve zamana bağlı basınç ve eğilme dayanımı gelişimleri belirlenmiştir. Deneysel çalışmalar sonucunda, %16 SiO2 katkılı ve %50 CaSO4 katkılı KAÇ içeren harçların, taze hal özelliklerinde kullanım alanlarına uygun gelişmiş özellikler kazandırabildiği ve hidratasyon sürecinde kararlı ürünler elde ederek zamana bağlı bir mukavemet kaybına uğramadan, 400 günlük periyot sonunda dayanım gelişimi gösterdiği sonucuna ulaşılmıştır.
