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.
