- Synopsis
- There is the following problem when the melting slag of the trash and the drainage sludge is used as a concrete aggregate. 1) Deterioration of consistency. 2) Deterioration of the strength. 3) Deterioration of the durability.
- And, it sometimes expands with some of the slag. Therefore, a countermeasure method was examined. That way of solving it is to add drainage sludge powder. And, agent was developed toward the repression of swelling. Furthermore, the execution examination of the actual structure thing which slow cooling slag was used for was done.
