Method of producing inorganic hydraulic binders

Abstract

Method of producing binders for building and building products cosisting in that a material of man-made and / or natural origin from a set comprising solid products produced by burning of solid fuels, metallurgical slag, ground fire products, products from burnt out mining deep stock piles after mining of fossil fuels, glass production waste, ceramic production waste, brick and concrete construction waste, heat-activated clays, low-crystalline pyroclastic rocks, sedimentary laterite, bauxite, opalolite, allophanolite, diatomite rocks, limestones and claystones and clays, is subjected to physical treatment consisting in action of a power pulse, during which mechanical energy Etk is passed on to the particles of the material treated by acting of a force of the size from 50 to 3.105 N, related to 1 g of the treated material, during a very short time in the range from 1.10-6 to 1.10-2 s or more subsequent pulses that cause passing on of mechanical energy Etk to grains of the material treated and / or passing on of magnetic energy Etm to its grains together with passing on of mechanical energy and / or after it by means of alternate and / or variable magnetic field having frequency from 15.101 to 15.106 Hz and intensity from 10-2 to 103 T, which acts on particles of the ferromagnetic substances if they are present in the treated material and / or on charges in defects of grains of the material, which defects were produced as a result of passing on of mechanical energy, what is having as consequence that the internal energy of the material treated is increasing, the particles of which are becoming more fine at least to 200 micrometers.

Description

technical field [0001] The present invention relates to a process for the manufacture of inorganic hydraulic binders. Background technique [0002] Adhesives are currently in great demand in various industries, in particular eg in the construction industry or in agriculture. The price of organic and inorganic binders continues to increase, which, together with the increase in input prices, especially energy, represents a huge economic burden for the industrial sector in which they are consumed in large quantities. On the other hand, in some industries, especially in the energy, metallurgy and mining industries, large amounts of waste or simply difficult to utilize by-products occur. They are a considerable burden on the environment. Only a small fraction (10% to 20%) of these materials find use as a substitute for small aggregates in simpler fields, such as fillers in construction materials, or as so-called "mixed" or "ash-containing" cements. The so-called volcanic ash p...

Problems solved by technology

However, their manufacture is relatively difficult, their handling is quite different from conventional practice in handling conventional building materials, and they come with many additional complexities

Thus, while having a relatively wide range of interesting features, they have not found much practical application
