Abstract:
Extensive investigations at the Concrete Research Institute of the Dutch Cement Industry have shown that the difference in resistance to the alkali-aggregate reaction and sulphate attack between OPC and blastfurnace cement concretes is caused by the difference in permeability to ions and water. In this paper an investigation is described on the effect of high curing temperatures on the above mentioned difference in permeability. A model is given which explains both the difference in permeability between OPC and blended cements and the effect of temperature on this difference.
