THE EFFECT OF MOISTURE ON THE THERMAL CONDUCTIVITY OF LIGHTWEIGHT AGGREGATE CONCRETE.

Author(s) : STUCKES A. D., TINKER J. A., SIMPSON A.

Type of article: Article

Summary

THE THERMAL CONDUCTIVITY OF 13 SPECIMENS OF LIGHTWEIGHT CONCRETE, INCORPORATING EITHER LYTAG, PELLITE OR AGLITE AGGREGATES, VARYING IN DENSITY FROM 1,144-1,424 KG/M3 HAVE BEEN MEASURED AT MOISTURE CONTENTS BETWEEN 0.03 AND 19.75% BY VOLUME. ALTHOUGH THE CONDUCTIVITY INCREASED WITH INCREASING MOISTURE CONTENT, THE CHANGE WAS MUCH LESS THAN THAT PREDICTED BY THE JAKOB FACTORS. A GENERAL EXPRESSION HAS BEEN DERIVED RELATING THE MOISTURE FACTOR TO BOTH DENSITY AND MOISTURE CONTENT BY VOLUME OVER THE RANGE 0-4%. A COMPARISON HAS BEEN MADE BETWEEN RESULTS USING THIS EXPRESSION, AND EXPERIMENTAL RESULTS AT 3% MOISTURE CONTENT. CLOSE AGREEMENT WAS OBTAINED.
