Ancient analogues of cement-based materials: stability of calcium silicate hydrates

Values for the durability of cernent matrices for a period of over a hundred years cannot be reasonably obtained from laboratory experiments. A knowledge of these is, however, essential for estimating the long-term behaviour of cement constructions, especially in the disposal of nuclear wastes. Afte...

Description
Summary:Values for the durability of cernent matrices for a period of over a hundred years cannot be reasonably obtained from laboratory experiments. A knowledge of these is, however, essential for estimating the long-term behaviour of cement constructions, especially in the disposal of nuclear wastes. After a review of the literature an attempt is made to show the contribution that a specific detailed study of ancient cements (Gallo-Roman cements, with ages >1500 a) can provide, particularly for knowledge of the stability of some phases of modern cement matrices (longevity of C-S-H with a low C/S ratio).
