An Appraisal of Hydration Characteristics of Dead Burnt Dolomite Grains

CODEN: JTEVAB

Abstract

Five different Indian dolomites are densified by the process of two-stage sintering at 1923 K (1650°C). Hydration of the dead burnt dolomite by all three test methods is found to be strongly influenced by the bulk density and grain size of the dolomite. In spite of wide variations in test conditions, equivalent disintegrating actions have been identified by varying test duration. In all three test methods the distintegration of doloma grain during hydration has been found to be related to the generation of Ca(OH)2. Selective hydration of CaO has been confirmed by SEM study. Results on the disintegration characteristics, bulk density, and rehydration behavior of the hydrated doloma grain are also presented.
