Densified cement ultra-fine particle-based materials
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). The dense packing is achieved by using a large quantity of superplasticizer. Concrete made with the new binder is far more durable than ordinary concrete and has a 3-5 times higher compressive strength than this (120-270 MPa). The geometric, kinematic and dynamic principles for arranging the fine particles in a dense structure are discussed, with special reference to the role of dispersing agents. The chapters on the hardened materials and applications concentrate mainly on the principles for developing new composite materials and structures that combine the excellent properties of the new binder with properties which this does not posses, for example, high tensile strength and ductility.
