NEW STUDY ON REACTIONS IN BURNING CEMENT RAW MATERIALS

THE TERNARY SYSTEM CALCIUM OXIDE-ALUMINUM OXIDE-SILICON OXIDE INVOLVES THE THREE PRINCIPAL OXIDE CONSTITUENTS OF PORTLAND CEMENT. THE PHASE DIAGRAM IS STUDIED WITH REFERENCE TO THE REACTIONS WHICH OCCUR WHEN TERNARY CEMENT COMPOSITIONS ARE BURNED. THROUGH THIS STUDY SOME PRINCIPLES CAPABLE OF EXTENSION TO THE COMMERCIAL PROCESS OF CEMENT MANUFACTURE ARE DEMONSTRATED. THESE INCLUDE THE RELATION OF COMPOSITION TO THE PROPORTION OF LIQUID FORMED IN THE BURNING OPERATION, THE TECHNICAL LIME LIMIT, AND THE INFLUENCE OF CHANGES IN COMPOSITION ON RETENTION OF CLINKER COATING IN THE KILN. THE INFLUENCE OF THE BURNING AND COOLING OPERATIONS ON THE CONSTITUTION OF CEMENT CLINKER IS DISCUSSED BRIEFLY. /PCA/
