AbstractMany types of admixtures are being used in concrete for obtaining better workability, retardation or acceleration of setting, improved mechanical properties, etc. There is no doubt that for more judicial and efficient use and also for the development of new types of admixtures, a basic understanding of their action in cement is essential. The mechanism is involved and complex and hence attempts are being made to explore new methods of approach. The technique of differential thermal analysis (DTA) has largely been used as an adjunct or a subsidiary technique to investigate the role of admixtures. It is possible, by a systematic approach, to use DTA as the main source of information in many cases. Thermograms may be used to study the kinetics of hydration, the mechanism of action of admixtures, and for the identification and estimation of new products that may form in the presence of admixtures. In some instances thermograms provide information not easiliy obtainable by other techniques. By means of typical examples this paper attempts to examine the application of DTA to a study of the different aspects of the action of various types of admixtures on the hydration of cement.
