AN 'ISOTHERMAL' CONDUCTION CALORIMETER FOR STUDY OF THE EARLY HYDRATION REACTIONS OF PORTLAND CEMENTS

THE CONSTRUCTION, CALIBRATION, AND OPERATION OF A CONDUCTION CALORIMETER FOR MEASURING THE HEAT EVOLVED BY HYDRATING PORTLAND CEMENTS ARE DESCRIBED. BECAUSE ONLY A SMALL SAMPLE OF CEMENT IS REQUIRED (8 GRAMS) AND THE HEAT PATH IS SHORT, THE CALORIMETER IS VERY NEARLY ISOTHERMAL. BY OPERATING AT VARIOUS SELECTED TEMPERATURES, THE EFFECT OF TEMPERATURE ON HYDRATION REACTIONS MAY BE STUDIED. THE CALORIMETER IS ALSO SUITABLE FOR GENERAL USE, SUCH AS STUDY OF THE INFLUENCE OF CHEMICAL ADMIXTURES AND OTHER ADDITIONS ON THE EARLY HYDRATION REACTIONS. /PCA/
