| Research Abstract |
The decomposition process of cement-asbestos composites when a small amount of salt is added was investigated. The most effective additive, CaCl_2, makes recycling of decomposed products into raw materials for cement difficult due to increase in Cl content from formation of Ca_2SiO_4・CaCl_2. The compound was synthesized and thermal properties were measured. Removal of Cl content in the actual processed material was difficult, thus we investigated decomposition additives without Cl content and methods to reduce processing time.
