Abstract

Self-compacting concretes (SCC), a new type of concrete, were realized with the development of polycarboxylate-based chemical additives. The interaction of these additives with the powder materials in the nano and micro scales affects the fresh and hardened properties of concrete in meso and macro scales. To change and improve the macro-dimensional properties of concrete, it is necessary to better analyze the nano-micro-dimensional interaction. The aim of this study is to examine the interactions of cement, mineral and chemical additives in micro scale. For this purpose, the zeta potential values of the mixtures consisting of cement, water, calcite and blast furnace slag prepared by using a polycarboxylate based plasticizer additive were analyzed. In addition, SEM analyzes of hardened samples were made on the 28th days.

Özet

Polikarboksilat esaslı kimyasal katkıların geliştirilmesi ile yeni bir beton türü olan kendiliğinden yerleşen betonlar (KYB) hayata geçirilmiştir. Bu katkı maddelerinin nano ve mikro boyutlardaki toz malzemelerle etkileşimi, betonun taze ve sertleşmiş özelliklerini mezo ve makro boyutlarda etkilemektedir. Betonun makro boyutlu özelliklerini değiştirmek ve iyileştirmek için nano-mikro boyutlu etkileşimini daha iyi analiz etmek gerekmektedir. Bu çalışmanın amacı çimento, mineral ve kimyasal katkı maddelerinin etkileşimlerini mikro ölçekte incelemektir. Bu amaçla polikarboksilat esaslı plastikleştirici katkı kullanılarak hazırlanan çimento, su, kalsit ve yüksek fırın cürufundan oluşan karışımların zeta potansiyel değerleri analiz edilmiştir. Ayrıca 28. günde sertleşmiş numunelerin SEM analizleri yapılmıştır.
