 Abstract
Recently, many researchers of the construction materials field are concerned about eco-friendly concrete in the construction industry due to the greenhouse gas reduction problem and international issue. In this paper, we investigates the effect of the kinds and replacement ratio of cementitous materials including fly ash and granulated blast furnace slag powder on the fluidity, setting time, temperature rise, compressive strength and drying shrinkage of eco-friendly low cement concrete with 3 types of binders. Fly ash and granulated blast furnace slag powder were used to replace Portland cement at replacement ratios of 70, 80, and 90% by binder mass. Test results demonstrate that the fluidity, compressive strength and salt damage resistance of the eco-friendly low cement concrete mixes were better than that of the control mix. In addition, the peak temperature of the eco-friendly low cement concrete was 4.0 to lower than that of the control mix. In this investigation, 10% cementitous materials replacement caused a reduction in the peak temperature of about 0.3 to in the concrete mixes. The setting time of F10S80 concrete mix (cementitous materials replacement ratio 90%; fly ash 10% and granulated blast furnace slag 80%) was similar to that of the control mix.
