Study on engineering properties of mortar containing a ternary binder, including cement, fly ash, and sugar cane bagasse ash

Abstract

The purpose of this study is to survey the properties of mortars that contain a ternary binder, which includes cement, fly ash, and sugar cane bagasse ash. Ten mortar mixtures are created: the control mixture uses only cement binder, while the other mixtures are created by replacing 10%, 15%, and 20% of cement with fly ash and sugar cane bagasse ash. Three mortar mixtures containing a ternary binder are created by combining fly ash and sugar cane bagasse ash to replace 20% of cement. The mortar mixtures are evaluated for workability, unit weight, specific gravity, compressive strength, and flexural strength. The research results indicate that sugar cane bagasse ash reduces workability, unit weight, and specific gravity of mortar, and mortar mixtures develop strength late. On the other hand, fly ash has a positive effect on the flexibility and mechanical properties of mortars. Mortars containing a ternary binder have properties that are equivalent to the control mixture.
