DILATOMETER METHOD FOR DETERMINATION OF THERMAL COEFFICIENT OF EXPANSION OF FINE AND COARSE AGGREGATE

THE METHOD IS PARTICULARLY ADAPTABLE TO THE STUDY OF SANDS AND ALSO PROVIDES A MEANS OF OBTAINING AND TESTING A REPRESENTATIVE SAMPLE OF A HETEROGENEOUS COARSE AGGREGATE OR OF THE VARIOUS MINERALOGICAL PORTIONS COMPRISING THE COARSE AGGREGATE. IT DETERMINES THE CUBICAL THERMAL COEFFICIENT OF EXPANSION FROM WHICH THE MEAN LINEAR THERMAL EXPANSION MAY BE CALCULATED. WITH THE PRESENT APPARATUS, THE THERMAL COEFFICIENT IS MEASURED OVER A RANGE OF APPROXIMATELY 7 DEG. F. BOTH THE TEMPERATURE INCREMENT AND THE BASE TEMPERATURE USED IN THE DETERMINATION CAN BE EASILY MODIFIED. THE ACCURACY OF THE APPARATUS HAD BEEN VERIFIED BY THE COMPARISON OF RESULTS OBTAINED WITH MATERIALS OF KNOWN THERMAL COEFFICIENTS OF EXPANSION. THE THERMAL COEFFICIENTS OF EXPANSION OF VARIOUS FINE AND COARSE AGGREGATES ARE INCLUDED. /AUTHOR/
