Abstract: The invention consists of the application of both fuel and water in engines and is characterised by the simultaneous vaporisation of these substances using one or more injection pumps of the type used for diesel and petrol injection engines. The fuel could be petrol, diesel, vegetable oil or another appropriate substance. Demineralised water is preferred to ordinary water. Blends of various fuels can also be used. The quantity of fuel and air can be adjusted for the proper operation of the engine. According to the method, water is transformed into high-pressure steam. The phase transformation requires relatively little energy. This energy can be obtained from the fuel which is transferred into the engine. The pressure of the steam and the gases which are released with the fuel explosion provide kinetic energy.

Abstract: Emulsions of mineral automobile fuel, such as gasoline and diesel oil, and containing at least 77 percent by weight of water, are described as a usable motor fuel. When vegetable oil is worked into the mixture, the automotive fuel can contain a percentage of water that can vary over a wide range. The advantages in using fuel mixtures are lower fuel consumption, lower CO2 emissions, affordable automobile fuel, and a lengthening of the period for which the increasingly scarce reserves of mineral oil will be available.

Abstract: Method to manufacture useful building bricks, blocks and elements by pressing granulated or partly granulated material comprising fly ash that may vary in quantity up to 92% of by weight, and cement. The average apparent density of the building materials may vary from aerated concrete density, which is 0.8 to 1.52 gram per cubic centimetre. The granulated or partly granulated mixture is formed to brick, block or element in a press, characterizing the process, suitable to compact the material under specific pressures varying up to 35 Newton per square millimetre of mixture mass. The press is of the type known as Sand Lime Brick press. The moisture content of to compress and to form mass may not exceed 13%, to enable the automatically working clamp of the press to take off rows of building blocks and the like and to place the rows on top of each other on a hardening car. Hardening of the products takes place under known cement hardening conditions.

Abstract: The pozzolanic properteis of a pozzolanic material, such as a fly ash, are improved by mixing the pozzolanic material with a calcium oxide or calcium hydroxide containing material and water in such a way that at the time of associating or bringing together the abovementioned components the mixture has or immediately attains a temperature of more than 50.degree. C., preferably at least 80.degree. C., most preferably 85.degree. to 100.degree. C.A mixture of pozzolanic material and calciumoxyde and/or calcium hydroxide may be preheated, water subsequently is added to said mixture.Hot water may be used and is preferably added as one mass at one moment.The pozzolanic material obtained from the process of the invention is suitable as cement substitute, as material for manufacturing building articles and a binder for occluding one or more fillers to be introduced into a chemical process or one or more fillers presenting noxious properties.

Abstract: A method is described for producing a building element in which a hardenable binder-material is mixed with a coarse particles comprising material after which the mixture is used for forming unhardened building elements. The building elements are subsequently hardened at a temperature up to 100.degree. C. and at atmospheric pressure in a water-vapor containing atmosphere. The hardenable binder material is constituted by a separately prepared mixture of fly ash; Ca(OH).sub.2 or a substance which may be converted into Ca(OH).sub.2, and water.Optionally the hardenable mixture may be partially granulated before use.

Abstract: The pozzolanic properties of a pozzolanic material, more particularly a fly ash, are improved by mixing the pozzolanic material with a calciumoxyde or calciumhydroxide containing material and water in such a way that at the time of associating or bringing together the abovementioned components the mixture has or immediately attains a temperature of more than 50.degree. C., preferably at least 80.degree. C., most preferably 85.degree. to 100.degree. C.A mixture of pozzolanic material and calciumoxyde and/or calciumhydroxide may be preheated, subsequently, water being added to said mixture.Water as used may be hot water and said water is preferably added as one mass at one moment.The pozzolanic material obtained from the process of the invention is suitable as cement substitute, as material for manufacturing building articles and a binder for occluding one or more fillers to be introduced into a chemical process or one or more fillers presenting noxious properties.

Abstract: Granulated material, at least comprising a filler, being bound by an inorganic binder, which filler consists at least partially of a substance possessing latent hydraulic properties, in the form of a substance possessing pozzolanic properties, preferably fly ash, and process for obtaining said material by starting from a calcium oxide product, silica granulate and water in which a portion of the heat development is absorbed by said granulate and is recuperated.

Abstract: Hydrothermally cured articles are formed by mixing a filler and a binder, moulding this mixture and coating said moulded articles with silica or calcium hydroxide particles. Hydrothermal curing may comprise a first step, wherein the steam pressure in the autoclave is increased, thereafter the steam pressure is decreased and subsequently the pressure is increased to a steam pressure being higher than in the first step.

Abstract: The invention relates to a method of producing silicate-containing granulates having a density of more than 0.7 kg/dm3 and a size of 2 to 40 mm, by mixing sand, a calcium oxide-containing product and water, forming granules and curing same in a moist atmosphere without any substantial condensation of moisture upon the granules to be cured.The granules contain 10 to 14% of moisture and curing is effected at temperatures above 90.degree. C.The granules may contain a filler, such as fly ash.
