ON THE DEVELOPMENT OF HYDRATE CRYSTAL MORPHOLOGY IN SILICATE CEMENT BINDERS

The cement paste is in itself a composite multiphase material, in which the cement gel, of mainly C-S-H composition, is the bearer of the cohesive and adhesive properties. The commonly accepted view, that this gel is a degenerate form of the mineral tobermorite, is questioned, and the evidence from structural analyses is reviewed. An alternative structure, built with elements fundamentally different from those of tobermorite, is suggested and described. The morphologic growth and the hydraulic properties of cement gel are discussed in terms of this alternative structure, the elements of which are columnar rather than lamellar.
