THEORETICAL AND EXPERIMENTAL RESEARCH ON THE THERMAL CONDUCTIVITY OF CONCRETE

THE ESSENTIAL FACTORS THAT INFLUENCE THE CONDUCTION OF HEAT IN CONCRETE ARE' THE CONDUCTIVITY OF CEMENT, THE CEMENT FACTOR, THE CONDUCTIVITY OF THE AGGREGATE, THE COMPACTNESS OF THE CONCRETE AND ITS MOISTURE. THE FACTORS THEORETICAL INFLUENCE WAS STUDIED TO DETERMINE THE CONDUCTIVITY OF THE DRY AND COMPACTED CEMENT. THIS RELATIONSHIP WAS EXPRESSED IN TERMS OF THE CONDUCTIVITIES OF THE CEMENT AND AGGREGATE AND IN PROPORTION IN VOLUME OF THE AGGREGATE. THE INFLUENCE OF MOISTURE ON THE CONDUCTIVITY OF CONCRETES USING KRISCHERS HYPOTHESIS WAS ALSO STUDIED. BY COMBINING ALL THIS DATA, IT IS POSSIBLE TO DETERMINE THE CONDUCTIVITY OF ANY CONCRETE, IF ITS COMPOSITION, ITS POROSITY AND ITS DEGREE OF MOISTURE ARE KNOWN. THE CONDUCTIVITY OF ROCKS THAT MAY BE USED AS AGGREGATES IN MAKING CONCRETES WAS ALSO CONSIDERED.
