Pozzolana and Pozzolanic Cements—A Review Part—II: Pozzolanic Cements

In this review pozzolanic cements have been discussed. A certain amount of pozzolana can be mixed with Portland cement to yield pozzolanic cements and thus the mixture becomes economic as well as inter-reactive. The specific advantages are its better strength, improved workability, less heat of hydration, less shrinkage and greater resistance to chemical attack and cracking. The improvement of properties as well as their mechanisms have teen discussed.
