process of producing pozzolan

Disclosed is a process for the calcining and manufacturing of synthetic pozzolan with desirable color properties. Feed material is dried, crushed, and preheated in a drier crusher. The dry, crushed material is collected and fed to a calciner where it is heated to become a synthetic pozzolan.

The advantages of lime pozzolan. Until now. While the new iteration of lime pozzolan is clearly based on this ancient construction process, Ramboll's Dr Ellen Grist, who compiled the research doctorate that developed the current lime pozzolan prototype, is keen to point out that it is not merely the reintroduction of an old material.
