Abstract The objective of this study is to investigate the effect of foaming agents and the incorporation of CBS-dust as a binder of light-weight foam concrete with 0.5 t/m3 of density on the performances of light-weight foam concrete using image analysis by the foam analyzer. Four different types of foaming agent are adpoted including Cationic foaming agent(CF), Anionic foaming agent(AF), Fe-protein foaming agent(FF) and Synthetic foaming agent(SF). To invesitgate the foaming capability and stability, foam analyzer is used. For binder compositions of lightweight foam concrete, Chlorine bypass system-dust(CBS?dust), which is collected at the cement production process, and granulated blast furnace slag(GBFS) are incorporated with Ordinary Portland cement ranged from 15% to 65%, respectively to facilitate settlement of light-weight foamed concrete. Test results indicated that the combinations of the AF with 0.2% and 5% of CBS-dust as blast furnace slag-based binders contribute to improve the resistance to settlement, strength enhancement of light-weight foamed concrete.
