AbstractAbout AuthorsReferences
The properties of dry mixtures consisting of nano-modified cement (NMC) (produced according to the pre-standard of the Russian Federation PST 19-2014) and fiberglass materials are presented. A new concept of fibrous NMC-stone as a composite material is introduced in contrast to the granular material on conventional cement. Recommendations about the sizes of fibers of the reinforcing material depending on the sizes of cement particles are made. An explanation of the absence of corrosion of vitreous materials in the NMC-stone is presented. The possibility of using glass fiber production waste and heat-insulating materials from non-alkali-resistant products as a reinforcing component in the composition of dry mixtures is shown. An explanation of the effect of a sharp (several times) increase in tensile strength and, as a consequence, reducing the brittleness of the new material is given. The method of manufacturing dry mixtures based on fibrous NMC is described in detail. The data of laboratory and production studies confirming the predicted positive effects are presented. It is shown that the fibrous NMC obtained by this method meets all the requirements of the latest standard for cements for transport construction GOST R 55224-2012 “Cements for transport construction. Technical conditions” with a reduced cost of production.
