摘要： Shaped articles with a coherent matrix comprising homogeneously arranged bodies (A) (18, 14) of a size of from about 50 66 to about 0.5 (Alpha)m, such as silica dust particles, and densely packed bodies or particles (B) (12) having a size of the order of from 0.5 - 100(Alpha)m and being at least one order of magnitude larger than the respective particles or bodies (A), such as Portland cement particles, and optionally additionally comprising, embedded in the matrix, solid particles (C) of a material having a strength exceeding that of ordinary sand and stone used for ordinary concrete, such as refractory grade bauxite, the particles (A) being homogeneously distributed, especially densely packed, in the void volume between the particles (B), are made from an easily flowable composite material containing a very low amount of liquid such as water and an extremely high amount of a dispersing agent such as a concrete superplasticizer. Test specimens comprising Portland cement/silica dust matrix with refractory grade bauxite embedded therein have higher compressive strength than hitherto reported for any cement-based matrix, which means that the matrix material makes it possible to construct larger structures with size in excess of what is possible with known structural materials such as high quality concrete and structural steel. Portland cement-based material may be used as a replacement for plastic, glass and steel such as for tools for making automobile steel body parts by compression. More generally, a new class of material is disclosed, not limited to cement systems, where the fundamental principle is utilization of known geometric and kinematic principles for arrangement of larger bodies or particles (12) in desired configuration relative to each other, in particular dense packing, in systems of fine particles or bodies (18, 14) which are 1 -2 orders of magnitude finer than the body or particle systems in which it has so far been possible to benefit from knowledge of large body geometry and kinematics, overcoming, by means of dispersing agent, the locking surface forces between adjacent bodies which hitherto prevented bodies or particles of micro and submicro size to be arranged densely according to pure geometric and kinematic principles. Application of these principles permits production of a variety of new materials of hitherto unknown high quality such as high performance fiber/ metal matrix composites where the compressive strength and abrasion resistance of the metal matrix is strongly improved by introducing submicro particles (A) (18) which is made possible by the particle arrangement principle where locking surface forces have been overcome. In spite of a high content of fibers such as 50% by volume of high strength very thin fibers in the 5 - 10 micron range, densely packed particles (A) (18) may be introduced by shaping the particle/fiber system with an auxiliary vehicle (20) such as water which is then substituted with the final inter-particle substance such as a metal in a subsequent process such as infiltration.

摘要： In composite materials comprising an organic and/or inorganic matrix, e.g. a cement matrix, reinforcing bodies such as fibers are surrounded by a contact domain comprising a material which is different in composition from as well the matrix as the fiber. The contact domain comprises a material such as a polymer which provides slidability of the fiber in the matrix so as to provide a controlled bond strength between the reinforcing body and the matrix, and/or the contact domain comprises ultra fine silica particles. Ultra fine silica particles provide a chemical protection of glass fibers. The matrix is particularly a cement/ultra fine silica matrix where the cement particles are densely packed and the ultra fine silica is homogeneously arranged and preferably substantially densely packed in the voids between the cement particles. Such matrix is prepared from a slurry of a very low water content by means of a concrete superplasticizer. Protection of silicate fibers against deterioration is obtained by incorporation of a catalyst poison.

摘要： Shaped articles with a coherent matrix which comprises homogeneously arranged inorganic solid particles (A) of a size of from about 50 66 to about 0.5 micron, such as silica dust particles, and densely packed solid particles (B) having a size of the order of 0.5 - 100 micron and being at least one order of magnitude larger than the respective particles A, such as Portland cement particles, the particles A being homogeneously distributed, especially densely packed, in the void volume between the particles, B, are made from an easily flowable composite material containing a very low amount of liquid and an extremely high amount of a dispersing agent, such as a concrete superplasticiser. Test specimens with Portland cement-silica dust-based matrices with dense packing of the silica dust have higher compressive strengths than hitherto reported, and reinforcements such as fibers or steel bars are subject to a high degree of fixation in the dense Portland cement-silica dust matrix because of the density of the matrix contacting the reinforcement such as illustrated in Fig. 5 which shows a plastic fiber incorporated in the dense matrix. Composite material for making shaped article comprises dispersing agent in sufficiently high amount to obtain a viscous to plastic consistency of the composite material with the small volume of liquid necessary to fill voids between particles A and B. The shaping of the composite material may be performed in a low stress field and without exchange of liquid with the surroundings.
