abstract
The heat of hydration evolution of three cement pastes having varying water to cement ratio and one cement paste with polycarboxylate superplasticizer have been studied by means of isothermal calorimetry during the first 7 days of the hydration process and by means of solution calorimetry for up to 120 days. The results of early heat of hydration values obtained by both methods are comparable. The heat evolution of cement paste (expressed in Joules per gram of portland cement) is increasing with increasing water to cement ratio. The superplasticizer is acting as retarder in first days of hydration, but after 7 days the influence of superplasticizer is negligible. The values obtained by solution and isothermal calorimetry for other samples containing silica fume as mineral admixture differ though. The results from isothermal calorimetry show an acceleration of the hydration process by the presence of the fine particles of silica fume.
