    Abstract: Method for treatment of fly ash for preparation of mortars and concretes. The invention is characterized in, that in a first step fly ash is intensively blended with a highly-reactive and dry cement mixture, which mixture have been obtained by mixing Portland cement with a microfiller and possibly a water reducing agent and by grinding said mixture, in that, in a second stage the so obtained blend is intergrinded in a vibratory milling device to achieve the fineness of the final product with a retention on a 45 nullm sieve which is less than 15 percent by weight.

    Abstract: A method of dusting-preventive treatment in which a powder having dusting property is treated with fibril-forming PTFE (polytetrafluoroethylene) to impart non-dusting property thereto and the non-dusting property of the powder, after having been reduced during transportation, are economically and advantageously recovered or improved through a relatively simple step. The method comprises: a first dusting-preventive treatment step in which fibril-forming polytetrafluoroethylene is added to a powder having dusting property, and a compression/shear force is exerted to the mixture at a temperature in the range of 20 to 200null C. to thereby regulate powder so as to have a flow value of 150 mm to 200 mm; and a second dusting-preventive treatment step in which a compression/shear force is exerted again at a temperature in the range of 50 to 150null C., without newly adding fibril-forming polytetrafluoroethylene, to the resultant powder after the powder treated in the first step has deteriorated in dusting-preventive property during transportation with transporting means due to such an external force that the polytetrafluoroethylene fibrils partly cleave or powder particles partly fall off polytetrafluoroethylene fibril nets.

    Abstract: A method for producing cement useful for preparing pastes, mortars, concretes and other cement-based materials, having a high workability with reduced water content, high strength and density, and a rapid development of strength, which method includes a mechanicochemical treatment of cement. The method includes a two-stage mechanicochemical treatment of a mixture of cement and at least one of two components, the first component being a SiO.sub.2 -containing microfiller and the second component being a polymer in the form of a powdery water-reducing agent. In the first stage the cement and the first and/or the second component are intensively mixed in a dry state, whereby particles of the first and/or the second component are adsorbed on the cement particles. In the second stage the mixture obtained in the first stage is treated in milling equipment where the particles in the mixture receive in quick succession a large number of direct-changed impact impulses resulting in modification of the surface properties of the cement particles in the form of substantial increase of surface energy and chemical reactivity. The treatment in the second stage is carried out during a sufficiently long period of time in order that a 1-day compressive strength of a 20 millimeter per side cube of cement paste, which has been properly compacted under vibration and hardened at +20.degree. C. in sealed conditions, at least equals 60 MPa.
