This chapter mainly illustrates that the mechanism and process of cold-bonding technique as well as using of three various innocuous recycling resources, construction residual soil, granite sludge, and lime sludge, to produce recycling coarse aggregates through the cold-

The attention of shortage of the primitive aggregate has been received in Taiwan. Although the natural resource in Taiwan is rather lack, the innocuous recycling resources are quite plentiful (e.g., construction residual soil, granite sludge, lime sludge, reservoir sediments, and so on). Using above-mentioned resources to manufacture the recycling green building materials is a good means in light of several aspects, including the reduction of waste, recycling of resource, and low carbon society. The Taiwan government has been devoted to developing the sustainability of society and has promulgated some acts to achieve this goal (Hsieh et al., 2012). Certainly, use of above-mentioned resources is one of the crucial issues because the resources and space for storing waste in Taiwan is so limited. Moreover, the global warming (or so-called climate change) is one of hot issues, in which how to reduce

For the promotion and facility of reuse and recycling of construction residual soil, which are generally sorted as 9 categories (i.e. B1 to B7) in Taiwan as shown in Table 1 (Industrial Technology Research Institute [ITRI], 1996). Herein the construction residual soils of B1, B2-1, B2-2, and B5 categories were immediately reused through uncomplicated process (like crushing and sieving, etc.), but the reuse rate of B2-3, B3, B4, B6, and B7 categories is extremely low due to their poor properties. According to the evaluation by the Construction and Planning Agency Ministry of the Interior, R.O.C. the construction residual soil of about 40 millions m3 is generated every year as shown in Table 2, and the B2-3, B3, B4, B6, and B7 categories with extremely low reuse rate accounted for more than
