Abstract
In this study, we examined whether the paper-ash could be used as a foaming agent for blast furnace slag-based foamed concrete. We attempted to examine the amount of hydrogen produced from paper-ash based on the mechanism of hydrogen generation caused by non-reacted Si and validated experimentally. The results of the experiment showed that the hydrogen generation caused by non-reacted Si of paper-ash was the highest at about 57 % of NaOH based on 100 % paper-ash consumption. In addition, it was found that 10.8 % of NaOH consumption was required when the paper-ash consumption amounted to 5 % of binder.
