In fact, published information appears to indicate that the ferrite phase imparts low strength characteristics to hydraulic Portland cements. For instance, Bogue in "The Chemistry of Portland Cement," second edition, Reinhold Publishing Corporation 1955, at page 672, FIG.

One of the desirable characteristics of an aqueous hydraulic cement slurry is that the fluid content thereof must not be readily lost to more porous medium, e.g., the geologic formation, for this causes the hydraulic cement slurry to prematurely set and thus be unsuitable in the cementing process.

Thus the cement that has been hardened will preserve its hardness and strength even when in contact with water. These characteristics make the hydraulic cements suitable for buildings in or during wet climates, suitable for structures that remain in contact with water, and for several other applications.
