Hydration behavior and mechanical properties of blended cement containing various amounts of rice husk ash in presence of metakaolin

This paper reports an experimental study carried out to investigate the effects of metakaolin and rice husk ash on the hydration behavior and mechanical properties of blended cement. The results showed that the combination of metakaolin and rice husk ash provides a positive effect on mechanical properties. The samples incorporating the ternary blends of cement with 20–15% metakaolin and 5–10% rice husk ash showed better compressive strength than that of the normal sample without rice husk ash. These blends proved to be the optimum combination for achieving maximum effect.
