摘要： Hydraulic cement or the like is poured into a closed mould under a reduced pressure condition to a level slightly higher than a predetermined level. Coarse aggregate and steel rods are prepacked in the mould. After pouring the pressure in the mould is increased to atmospheric pressure or a higher pressure to force the hydraulic cement above the predetermined level back into the space below the level thus compacting the poured in hydraulic cement. A cushion device is provided for the pouring device. An overflow tank is connected to the mould to observe the level of the poured cement. The pressure in the overflow tank is also decreased during pouring and increased after pouring.

摘要： A method and apparatus are provided for manufacturing articles made of hydraulic cement. The method includes the steps of preparing a plurality of moulding spaces adapted to be closed in a hermetic manner and having sufficient pressure-proof against the inner pressure therein, which pressure is raised during introduction and heat curing of hydraulic cement; introducing hydraulic cement into the mounding spaces substantially to fill the same by utilizing the pressure difference between the inner side and the outer side of the moulding space; indirectly heat curing the hydraulic cement substantially completely around the same immediately after the introduction of the cement is finished, the temperature thereof being rapidly raised up to more than 60.degree.C, and releasing the cured articles from the moulding spaces. The apparatus includes a vertical stack of a plurality of moulds, each including a side frame and a hollow bed overlying the side frame; sealing means interposed between the side frames and the beds for hermetically sealing the moulds; means for releasably interconnecting the stacked moulds; means for reducing the pressure in the moulds; means for pouring the hydraulic cement into the moulds; means for admitting a heating medium into said hollow beds, for indirectly heat curing said hydraulic substance poured into said moulds. This invention thus enables the manufacture of moulded articles of cement having high mechanical strength in a short time, and yet which can be readily removed from the moulds.

摘要： A method is provided for blasting concrete or mortar against a surface to be coated using a blasting nozzle. The method includes the steps of: preparing a slurry-like, freshly mixed, fluid composition by admixing a powder of an hydraulic substance and water; conveying the slurry-like freshly mixed fluid composition to a remote location through a conduit, under pressure; conveying an agreegate through a separate conduit to the remote location under pressure; combining the slurry-like composition and the aggregate at the remote location by introducing the slurry-like composition into the conduit conveying the aggregate to form a unified mixture and conveying the unified mixture through a common conduit to the blasting nozzle; and blasting the unified mixture against the surface to be coated the unified mixture being formed substantially immediately before the blasting nozzle. By the method, the generation of dust is minimized. It is possible thereby to produce thick layers of concrete having high strength.

摘要： A slurry shaped freshly mixed fluid compound such as paste or mortar and coarse or fine aggregate are conveyed under pressure through discrete conduits and then mixed together substantially immediately before blasting. The mixture is blasted through a nozzle against a body to be covered with concrete.

摘要： A plurality of moulds each including a side frame and a hollow bed overlying the side frame are vertically stacked with sealing members interposed between the beds and the side frames for hermetically sealing the moulds. While the pressure in the moulds is being reduced a hydraulic substance such as cement is poured into the moulds. The poured hydraulic substance is heat cured to produce solid articles releasable from the moulds. An empty mould is added to one side of the stack while a mould containing the cured substance is removed from the other side of the stack. Alternatively, the process can be carried out according to a batch system. The moulds may be packed with aggregate, fittings or means for interconnecting the articles.

摘要： The fluidity of a plastic fluid, cement mortar for example, is measured by passing the fluid through a flow passage packed with an aggregate for simulating an actual mould, measuring the flow pressure, and measuring the quantitative flow coefficient of the fluid with respect to the flow passage. The pressure remaining in the passage after the fluid has been poured into the passage and after the flow speed has been decreased to zero or the pressure after a quantity of the fluid has been added to the passage and prior to the discharge of the fluid from the passage is measured to determine the relative shear stress yielding value. Thereafter, the fluid is caused to flow to determine again the relative shear stress yielding value, and the relative closure coefficient is determined by the difference between said two relative shear stress yielding values. After the elapse of a predetermined time the plastic fluid is caused to flow under a pressure and the pressure at the commencement of the flow is measured to quantitatively determine the variation in the shear stress yielding value with time, thereby determining the relative inital flow pressure. The relative flow viscosity coefficient is measured by varying the flow speed of the plastic fluid and by determining the relationship between the speed and the pressure of the plastic fluid. In the actual moulding operation the plastic fluid is prepared by using the factors thus determined and the pouring conditions are predetermined, or automatically controlled. Thus, by using the measuring device simulating the actual prepacked mould, various data regarding the fluidity of cement mortar, etc., are determined. From these data optimum pouring conditions of the mould is predetermined. Accordingly, irrespective of the composition of the mortar, void free high quality products can be produced.
