This study proposes a new type of no-cement eco-binder which could serve as a potential material for bridge construction to facilitate its safety, maintenance and management. Such cement is denoted as the SFC binder and fabricated by a mixture of three industrial wastes of ground granulated blast furnace slag (S), Class F fly ash (F), and circulating fluidized bed combustion fly ash (C). Experimental results showed that the SFC binder illustrated significantly low heat evolution during hydration compared to that of ordinary Portland cement (OPC). The fresh selfcompacting concrete (SCC) produced with the optimized mix proportions of SFC binder (SFC-SCC) was reported to have excellent flowability and filling ability. The hardened SFC-SCC specimens had compressive strength high enough to be applicable for bridge construction with remarkably low drying shrinkage with equivalent 28-day compressive strength, and the confining SFC-SCC illustrated a bonding behavior with deformed steel rebar as good as that of the OPC concrete.
