摘要
The purpose of this study is to develop a technology for reusing the paper sludge and co-generation ashes generated by the paper industry. The study will include the following: (1) employing granulation technology to produce a light-weight aggregate with a specific gravity less than 1.0 from paper wastes sludge, and a light-weight aggregate with a specific gravity less than 1.5 from co-generation ashes; (2) employing compounding technology to mix co-generation ashes with ceramic materials, and then to make it into constructional bricks through forming and sintering processes. The physical property tests have proved that the granulated light-weight aggregates having potential to replace the natural aggregate to make light-weight concrete. The constructional bricks made from co-generation ashes and other raw materials have a water absorption rate lower than 15%, and compressive strength greater than 150 kgf/cm(2), can conform to CNS specifications.
