Abstract: A specific combination of components having unique properties both in composition and benefits. Such a combination has been found in alkali or alkaline earth metal nitrates, alkanolamines and alkali or alkaline earth metal thiocyanates. In such combinations it has also been found that alkaline and alkali earth thiosulfates and chlorides below the concentration level where corrosion is promoted may advantageously be substituted for all or part of the thiocyanates and that diethanolamine, N,N-di(hydroxyethyl)glycine (bicine) and N,N-di(hydroxyethyl)- beta -aminopropionic acid (DAPA) and certain alkanolamines and alkanolamino acids and derivatives may advantageously be substituted for all or part of the triethanolamine.

Abstract: 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.

Abstract: 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.
