EFFECTIVENESS OF ULTRA

This paper describes a new class of materials with binders of densely packed cement and ultra-fine particles arranged in the spaces between the cement. The new materials are shaped from a viscous mass in a low stress field - in spite of an extremely low water content (0.13 - 0.18 by weight of cement + ultra-fine particles).
