Description

This study aimed the utilization of waste gypsum board as raw materials. The merit of this recycle method is can be utilize waste gypsum boards without separate process of covered paper from gypsum layer. The conclusions of this experiment are as follows. 1. Most desirable curing method and mixing ratio for slag-gypsum boards were presented. 2. Concerning to the pretreatment of waste gypsum boards, wet crushing system produced better results than dry system. 3. It is found that waste gypsum boards can be utilize as the raw materials for slag-gypsum board by ordinary Hatcheck-system.
