摘要:
A method for producing a molten glass conveying equipment element. The molten glass conveying equipment element has a conduit structure for molten glass containing at least one conduit comprising platinum or a platinum alloy, a first ceramic structure provided around the conduit and a second ceramic structure located around the first ceramic structure. The method includes filling a gap between the conduit and the second ceramic structure with a slurry body, and sintering the slurry body at a temperature of 1,300 to 1,550° C., thereby forming the first ceramic structure. The slurry body is prepared by blending specific first particles, specific second particles and specific third particles with specific mass ratios.

Concrete reinforcing members having rolled cross sections, and methods for manufacturing and using such reinforcing members in concrete construction are disclosed herein. In one embodiment, a concrete reinforcing member is formed from a piece of metal having a first elongate edge portion spaced apart from a second elongate edge portion. The piece of metal further includes an inner surface portion extending between the first and second edge portions, and an outer surface portion extending between the first and second edge portions. In this embodiment, the piece of metal is rolled about a longitudinal axis in an overlapping fashion into coiled or spiral cross-sectional shape.

The present invention uses a three-dimensional metal reinforcing aggregate as an aggregate in producing a common ready-mixed concrete according to its object of use in producing the ready-mixed concrete and a mortar. Since it is the three-dimensional metal reinforcing aggregate, it is a technique to enhance the external pressure, internal pressure and tensile strength when the ready-mixed concrete is hardened and solidified. Since the three-dimensional metal reinforcing aggregate is forced into between an aggregate and an aggregate in the ready-mixed concrete, the aggregate and the aggregate are further bound, thereby enhancing the internal pressure, the external pressure and the tensile strength. For example, if split, crack and the like is generated on the concrete body near the cold joint of the placed concrete, the conventional concrete body leads to drop thereof and causes an accident. However, with the concrete body using the inventive three-dimensional metal reinforcing aggregate as the aggregate, even if the crack or the like is generated thereon, the three-dimensional metal reinforcing aggregate is coupled and connected with a variety of aggregates in the concrete body. Therefore, even if the split, crack or the like is generated thereon, it never leads to the drop. Consequently, it is a technique of high strength that can prevent the accident of concrete lump drop due to the cold joint and that also intends safety for a variety of structure of public works and buildings. It is an earthquake-resisting concrete that can construct structures such as bridges, dams, tunnels, buildings, airports, harbors and the like. It is characterized by using and mixing and kneading a three-dimensional metal reinforcing aggregate as an aggregate in manufacturing a ready-mixed concrete.

High-flexural-strength concrete is produced by mixing wet hydraulic cement-sand mixture with coarse, flat, tabular aggregate, pouring the resulting mixture into a form in a shallow layer, vibrating the form containing the mixture, thereby orienting the coarse aggregate particles, pouring another shallow layer of the mixture into the form, again vibrating the form, and repeating these processes until the form has been filled to the desired level. The mixture then is allowed to cure. Cast-in-place items are prepared by placing thin layers or lifts of oriented, tabular-aggregate concrete into conventional forms and vibrating each lift using flat-plate vibrators.

Soundproofing materials consisting essentially of zinc oxide whisker particles having a nucleus body and needle crystal portions extending radially from the central body in different plural directions. The materials may comprise a support material for supporting the zinc oxide whisker particles. Such support materials include inorganic materials such as metals, ceramics, glasses, cements, mortars and various fillers in the form of powder, flakes, fibers and the like, and organic materials such as resins, rubbers, waxes and the like. These materials are particularly suitable for sound insulation, sound proofing, vibration damping and vibration insulation.
