摘要： An apparatus for producing a spherical hydraulic material comprises a melting furnace (1) for melting raw materials of a hydraulic material and/or the hydraulic material, fine granulation means for finely granulating the molten material (2) such as a nozzle (4) or a high speed rotary member, a chamber (5) for accepting the finely granulated material, cooling it and converting it into spherical fine powder, and means (6, 7) for recovering the spherical fine powder. When the material molten in the melting furnace enters the chamber and is finely granulated, the molten material is immediately formed into a complete sphere because its surface tension is relatively great, and is cooled and recovered as the spherical fine powder. The resulting spherical hydraulic material is highly fluidized by a small amount of water, and turns to a molded article having high strength and high durability, and moreover, having an excellent dimensional accuracy. Spherical hydraulic material which is approximately in the form of a complete sphere, is extremely smooth on the particle surface and exhibits high fluidity can be obtained by using this apparatus. This hydraulic material can be produced without limiting the blend ratio of the starting components, and various ashes of an incinerator can be utilized as the hydraulic material. Moreover, maintenance becomes easy.

摘要： PURPOSE:To obtain the spherical hydraulic substance useful for producing highly strong moldings by spraying and cooling the melted hydraulic substance. CONSTITUTION:A cement raw material is melted in a melting oven 1 and subsequently transferred into a holding oven 3. The holding oven 3 has a nozzle 4 thereunder. The melted product 2 is sprayed into a tank 5 through the nozzle together with a high pressure gas charged from a high pressure gas bomb 8 or compressor. In the tank, the sprayed melted product is cooled into a spherical or powdery cement due to its surface tension during the process, and the cement is recovered in powder tanks 7 through a cyclone 6. A vacuum method or a centrifugal method except the gas atomization method is adopted. A cement raw material such as lime stone, clay, silica, slag, bauxite or iron raw material, a proper combination of coal ash, incineration ash, etc., or a hydraulic substance such as a cement or a cement clinker or their mixture is employed as the raw material. The diameter, particle distribution and crystallinity of the spherical particles are controlled by changing the surface tension, particle size, spraying condition and cooling condition of the melted substance.

摘要： PURPOSE:To inexpensively obtain concrete excellent in fluidity by including a globular hydraulic substance containing a globular clinker powder in concrete. CONSTITUTION:A globular hydraulic substance containing globular clinker powder is added to concrete and as necessary, further admixture selected from an amorphous hydraulic substance, water-reducing admixture, a high performance water-reducing admixture, an AE water-reducing admixture, a high- performance AE water-reducing agent and a fluidizing agent is added thereto to produce the objective concrete having fluidity. This globular clinker powder is preferably produced by a method, etc., melting a raw material of limestone, quartzite, etc., by an electric furnace, etc., then scattering the melted material by a combustion gas system, etc., and then cooling and solidifying the melted material in a scattered state. Since the globular hydraulic substance containing this globular clinker powder is contained in the concrete, slipping property of a substrate added therein can be improved and since the globular hydraulic substance has high fluidity, the objective compaction-free concrete having fluidity can inexpensively be produced.

摘要： PURPOSE:To obtain a durable grout which exhibits a desired flowability at a low water level, has enough strengths after curing, and allows no minute crack to occur on the surface by using spherical particles of a hydraulic material as the main component. CONSTITUTION:A grout containing particles of a hydraulic material as the main component. The mean diameter of the particles is pref. 500mum or lower in order to accelerate the hydration reaction, i.e., to quicken the hardening, and to increase the strengths after hardening. The material is produced, e.g. by thermally melting a feedstock mixture contg. limestone, clay, silica rock, iron feedstock, etc., and converting the resulting melt into spherical particles by the melt atomizing method wherein the melt is scattered by blowing a high- pressure gas to it or it is scatterd in a vacuum and cooled to solidify in a scattered state.

摘要： PURPOSE:To form a high strength concrete by compounding a globular hydraulic substance as a part or the whole part of the binder into concrete. CONSTITUTION:Raw materials which consist essentially of CaO, SiO2, Al2O3 and Fe2O3 are melted and it is cooled and solidified to produce the globular hydraulic substance having >=500mum particle diameter by spraying the melted product. Next, a specified amount of spheric hydraulic substance as a part or the whole part of the binder, and an additive such as a mixing agent and a shrinkage reducing agent, if necessary, are incorporated and mixed to obtain the objective concrete with a lower water cement ratio and an excellent fluidity. As a result, the vibrating compaction time is greatly shortened and also generation of noise is reduced. The high strength concrete product without defect is obtained by hardening this concrete.

摘要： PURPOSE:To improve the development of strength after curing by using spherical hydraulic particles of cement and gypsum as the major components to ensure the fluidity needed when kneaded with water by the ball bearing action, thus reducing the amount of water. CONSTITUTION:The self-leveling material is prepared from spherical particles of hydraulic dust (gypsum and cement). As the hydraulic dust is spherical, the fluidity needed can be obtained by their ball bearing action, even when the kneading water is reduced. Thus, no bleeding water occurs after application, no laitance is formed, curing is accelerated and the surface hardness is increased.

摘要： PURPOSE:To provide a method for reclaiming concrete waste capable of utilizing in a large amount as a material for civil works and building structures. CONSTITUTION:A concrete waste is directly melted at a high temperature or blended with a Ca-based raw material, etc., and then the blend is melted at a high temperature. Further, the substance melted at a high temperature is scattered from a nozzle together with a high pressure gas and cooled and solidified in a scattered state. Thereby, the concrete waste is converted to a globular hydraulic substance.
