<p><P>PROBLEM TO BE SOLVED: To provide ALC which corresponds to the depletion of the ore of a silica stone being a silicic raw material and where the usage of natural resources is reduced by substituting a fine copper slag aggregate for the silicic raw material. <P>SOLUTION: The fine copper slag aggregate is substituted for 30% or less of the silicic raw material. An ALC containing 3.9-15.8% of the fine copper slag aggregate is used. Quicklime, ordinary portland cement, gypsum and a recycled raw material are blended with a main raw material for a fine aggregate containing at least a silica sand of 70% or more and a copper slag of 30% or less. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
