SFC綠冷結磚由爐石(S)、F級飛灰(F)、CFBC灰(C)三種工業副產物拌合、加壓製程，材料方面此三種副產物之混合為本研究室首創，並稱其為SFC無水泥膠結材。配比方面F級飛灰佔總重10-30%、CFBC灰佔15-25%、爐石佔45-70%為此膠結材設計範圍。SFC膠結材工程性質依ASTM-C109、ASTM-C230、ASTM-C267、ASTM-C1260、ASTM-C642、ASTM-C1585等試驗均有優異表現並有成為新型綠建材之能力，故將SFC無水泥膠結材製成高壓磚相較於傳統燒磚、水泥製磚大量減少二氧化碳產生，並增加CFBC副產石灰應用範圍，儀器上使用本研究室設計之加壓彈力鋼模，優點為方便組合、拆解，加壓試體經28天養護強度可達 、吸水率低於 ，依CNS 382規範SFC綠冷結磚為一級磚之標準。
The engineering and microstructural properties of non－fired hydraulic eco－brick fabricated with purely 100% solid wastes including ground granulated blast furnace slag (GGBFS/slag), low calcium Class F fly ash (FFA), and circulating fluidized bed combustion (CFBC) fly ash (CFA), have been preliminarily explored. Experimental results showed that the hardened bricks illustrated the engineering properties mostly satisfying requirements for building brick, such as 28－day compressive strength sufficient for wide application for construction materials, high UPV values, low water absorption, high capacity of thermal isolation due to low values of thermal conductivity coefficient, and particularly high durability in terms of resistances to corrosion induced by severely attacking environment. The microstructural examination showed that the hydration products of the hardened bricks mainly consisted of C－S－H/C−A−S−H gels blending with tremendous amounts of ettringite (AFt) and monosulfate (AFm) phases. The addition of FFA as replacement for slag was encouraged to produce the resultant bricks with improved engineering and durability performances in both fresh and hardened stages due to the better packing of particles and improved microstructures induced by additional hydration products.
