Cementing Efficiency Of Flash And Rotary

The research focuses on strength efficiency of rotary kiln metakaolin and flash metakaolin in concrete. The Smith and Bolomey modified model is used to develop efficiency factor (k) for calculating strength efficiency in reference to pozzolan content and relative strength. The present study shows that as the replacement percentage of metakaolin ...
