Study on Recycling of Silicate Contained Wastes for Fiber Cement Board Cheng-Kuo Hsieh, T. H. Ueng and Jyh-Herng Chen
Abstract 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. Keywords Industrial wastes
Fiber cement board Recycling
40.1 Introduction In this study, silicate contained wastes, such as spent refractory materials, cutting sludge of dimension stone, or waste glass, are intended to be developed as recycling materials for replacing the silica sand materials used in the traditional fiber cement board [1, 2]. After the silicate contained wastes were processed through the C.-K.

high-pressure molding and high-temperature maintenance of fiber cement board production process, the difference of hydration reaction products was analyzed with XRD and SEM [3, 4]. Simultaneously, the physical properties of board materials were detected according to CNS13777, and also the usability of various silicate contained wastes in fiber cement board production process is discussed.
40.2 Fiber Cement Board Production Process Commercial production process of typical fiber cement board is as shown Fig. 40.1. In this study, the raw materials ratio and production process conditions provided by Germany SIEMPELKAMP Company that is in the leading position in fiber cement board factory equipment and technology were used as reference, as shown in Table 40.1. Silica sand is the primary raw material of fiber cement board, accounting for 52 % of the total materials.
40.3 Characteristics of Silicate Contained Raw Materials In this study, silicate contained wastes, such as granite material and sludge, spent refractory materials of silicon and aluminum, or waste glass, are attempted to be developed
