Method of producing binders for building and building products consisting of a material of man-made and/or natural origin from solid products produced by burning of solid fuels, metallurgical slag, ground fire products, products from burnt out mining deep stock piles, 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. The material 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 cause passing of mechanical energy Etk to grains of the material and/or passing of magnetic energy Etm to its grains together with passing 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. The energy 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. The defects were produced as a result of passing of mechanical energy. As a consequence the internal energy of the material treated increases and the particles become more fine at least to 200 micrometers. Re-aggregation of its particles is thus prevented and chemical reactivity of the material treated is increased to obtain dry binder and/or dry building material. Water is added in the quantity from 8.20 to 420% by weight, based on weight of the material treated to obtain formable wet binder and/or formable wet material, which can be formed to the desired form of products and/or hardened by autoclaving and/or dry warming up. |
