A GRAVIMETRIC METHOD FOR THE DETERMINATION OF BARIUM OXIDE IN PORTLAND CEMENT

ANALYSES FOR BARIUM OXIDE WERE REQUIRED TO ADD TO THE DATA ON THE CEMENTS USED IN THE LONG-TIME STUDY OF CEMENT PERFORMANCE IN CONCRETE. SINCE NO METHOD WAS AVAILABLE FOR THE ANALYSIS OF CEMENT FOR BARIUM, ONE WAS DEVELOPED. THE METHOD AS DEVELOPED AND DESCRIBED HERE CONSISTS ESSENTIALLY OF REMOVING ALL THE CONSTITUENTS OF THE CEMENT EXCEPT BARIUM AND WEIGHING THE LATTER AS THE SULFATE. THE ACCURACY OF THE METHOD WAS VERIFIED BY ANALYSES OF SYNTHETIC MIXTURES OF KNOWN BARIUM CONTENT. THE CEMENTS USED IN THE LONG-TIME STUDY WERE ANALYZED AND FOUND TO CONTAIN NEGLIGIBLE AMOUNTS OF BARIUM CALCULATED AS THE OXIDE. THE DETAILED PROCEDURE IS PRESENTED IN AN APPENDIX. /PCA/
