Abstract

Abstract Conduction calorimetry technique makes possible to follow the kinetic of cement hydration through the rate of heat evolution. This work presents experimental results using the following types of cement: oilwell Class G, Class A, Pozzolanic and Blast Furnace. The effects of cement aeration (carbonating and/or humidifying), temperature and use of additives on the hydration rate of Class G cement slurries were analysed. In addition, the characterization of the different cement types was performed. The tests were run in a JAF Conduction Calorimeter which working principles were described in the work. A computer program was developed to calculate the heat liberation rate and the cumulative heat of hydration generated along the process.
