Abstract:
Cement-based composition for the embedding of a boron-containing aqueous solution, said composition being composed of a sulphoaluminate cement optionally comprising gypsum, and of a sand.Process for embedding, by cementation, of a boron-containing aqueous solution in which said aqueous solution is kneaded, mixed with said cement-based composition.Cement grout composition thus obtained.
