METHOD FOR PRODUCING CIVIL ENGINEERING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a civil engineering material of a simple production method and of inexpensive production costs in order to promote the effective use of coal ash the amount of which is estimated to increase. SOLUTION: In the method for producing the civil engineering material, after 100 pts.wt. of the ash of an in-furnace type fluidized bed coal boiler and 20-50 pts.wt. of water are mixed in a granulator, the mixture is cured naturally, and cured grains 9.5 mm or below in average particle size are produced.
