Study on Recycling of Silicate Contained Wastes for Fiber Cement Board

摘要

In this study, silicate contained wastes, such as spent refractory materials, cutting sludge of dimension stone, or waste glass, were used in the traditional fiber cement board process to replace the conventional raw material of silica sand. It was demonstrated that the recycled materials could be prepared with good fire resistance and heat insulation properties. Materials tested according to CNS13777 regulation showed that recycled silicate contained materials could meet the commercial product specifications. Above-mentioned industrial wastes are suitable as the raw materials for fiber cement board.
