CEMENT BLOCK AND ITS MANUFACTURING METHOD |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To solve the problem that if a cement block using a conventional rubber chip aggregate is pressed at a molding or coating time, when a force is removed only by deforming the rubber, the block is returned to an original, and hence the pressing is not effective so that it is difficult to mold the block in a predetermined shape or thickness. <P>SOLUTION: The cement block comprises an aggregate layer containing an aggregate and provided on an upper surface of a cement body so that the aggregate has a surface material fixed to the surface of an elastic material chip. <P>COPYRIGHT: (C)2003,JPO</p> |
