Abstract

The invention provides a process of producing a porous body which exhibits sufficient strength although it is obtained by using fly ash as a main component. The porous bodies 9 are obtained by feeding fly ash 1, cement 2 and water 3 from respective feeders 12-14 of a main raw material slurry producing unit 10 into a mixer 11, then mixing the raw materials to prepare a main raw material slurry 4 having a viscosity of 200-1,200 cp, feeding the main raw material slurry 4 from a feeder 22 of a foamed slurry production unit 20 to a mixer 21, at the same time, feeding a protein-based foaming agent from a foaming unit 30 into the mixer 21, after stirring for producing a foamed slurry 6, pouring the foamed slurry 6 into a molding flask 41 of a porous body forming unit 40 so as to cast, subjecting to preliminary steam curing, removing a cured material from the molding flask 41, cutting the formed body 8 removed from the mold into pieces each having a predetermined size using a piano wire, and curing the pieces in a curing unit 42.

Description

[0001] Field of invention [0002] The present invention relates to a porous body containing fly ash, its production method and a foaming device for the production. Background technique [0003] In Japan, about 60% of the large amount of coal ash and other fly ash generated from thermal power plants can be reused, but the remaining about 40% cannot be reused and must be disposed of in landfills. This is because the chemical composition and particle size distribution are different depending on the production area of ​​the coal used, and the quality of the fly ash (specific surface area (particle size) and unburned component amount (carbon amount), etc.) is dispersed due to the power output during power generation. That is to say, at present, when overseas coal is mainly used, it is used in the form of powder raw materials, and the variation in properties is large, and it is difficult to meet the conditions for manufacturing stable products. [0004] In addition, most of the re...
