Implications of the use of low-pH cementitious materials in high activity radioactive waste repositories

Abstract:

The behaviour of low-pH concretes made of low-pH binders is different from that observed in conventional concretes and their development implies an exhaustive study of their compatibility with the chemical admixtures used when shotcreting. Besides, due to the location and the long service life of this type of products, their durability properties must be also guaranteed. Low-pH concretes have been designed within this study and their suitability in the construction of plugs for underground repositories has been evaluated. Durability parameters, such as their resistance to underground waters aggression, their shrinkage behaviour and the corrosion risk in case of using reinforcement concretes have also been taken into account.
