Title: Method for manufacturing an artificial lightweight aggregate containing bottom ash
Inventor: JEONG YOUNG HO
IPC: C04B18/06
Filed: 2007-04-03
Abstract: The present invention relates to a method for producing an artificial lightweight aggregate containing bottom ash, and more particularly to a method for producing an artificial lightweight aggregate containing bottom ash, the method comprises the steps of: (a) mixing 100 parts by weight of clay and 10-100 parts by weight of bottom ash to obtain a mixture; (b) extrusion-molding the mixture by using an extruder and cutting the extrusion-molded mixture to form a molded article; (c) drying the molded article by using a rotary drier; and (d) Sintering the dried article at 1050-1150 °C for 15-45 minutes to produce the artificial lightweight aggregate. The lightweight aggregate according to the present invention is produced by mixing bottom ash that did not satisfy a desired physical property of an aggregate with clay and dust in an optimum mixture ratio, so that the problem that there is a great deviation in water absorptions of a lightweight aggregates that are mass produced using existing fly ash was solved so as to reduce a deviation in water absorptions depending on a change in the amount of raw material added during mass production, thereby making it possible to produce an artificial lightweight aggregate having uniform water absorption. In addition, bottom ash that was difficult to dispose is disposed in a large quantity and thus the cost required for installation of an ash pond is reduced and the bottom ash is recycled so that the produced artificial lightweight aggregate is economically efficient. Also, it is possible to solve environment-related problems.

The photoelastic monitoring device is designed to be attached to a structure or a part. The monitoring device is attached to the structure in such a way that stresses and strains from the structure are transmitted into the photoelasti c monitoring device. When a certain predetermined stress or strain is reached, the monitoring device may deform plastically. The plastic deformation can then be detected in the photoelastic material using the integrated polarizer. Also in accordance with the present inventio n, a method is described for photoelasticanalysis. The method comprises providing a photoelastic material to be analyzed for stresses and strains. An integrated polarizer is attached directly on top of at least a portion of the photoelastic material. The integrated polarizer is attached in such a way such that the photoelastic material can be illuminated with regular ligh t through the integrated polarizer, and such that light can be reflected back through the photoelastic material and back through the integrated polarizer to the observer or the detector. The method comprises illuminating the polarizer with light, and viewing the reflections of light that have traveled through the integrated polarizer, through the photoelasti c material, and been reflected back through the photoelastic material and back through the integrated polarizer. Observing or detecting fringe patterns in the reflected light indicate the presence of strain or plastic deformation in the photoelastic material.

Abstract: A vessel receives a liquid material, which is freeze-dried in situ within the vessel. A gas permeable material carried by the vessel provides gas transport for sublimation during drying. After freeze drying, an oxygen-free inert gas is introduced into the vessel through the gas permeable material, to occupy the interior of the vessel with the freeze-dried material. The gas permeable material is covered, to trap the oxygen- free inert gas within the vessel with the freeze- dried material. The freeze-dried material is stored in the entrapped oxygen- free inert gas within the vessel for a storage period. The vessel receives a reconstituting liquid for mixing with the freeze-dried material, and conveys the reconstituted freeze-dried material from the vessel for administration to an individual.
