Pozolana is added to cement to increase early strength or reduce heat of hyderation, which is true?why?

05 May 2019 1 9K Report

Pozzolana is added to cement , this cement is used worldwide

The reduction in the heat of hydration is true when pozzolans are used. However, depending on the type of pozzolan used, only pozzolans containing high content of calcium increase the early strength.
