3hour and 1day is slightly lower compared to the regulated setting cement, but after the
3day, it shows a higher strength than the regulated setting cement.
4) In the event that only the EAFRS is used, it shows large length change according to
time. But as the gypsum is mixed, it secures the volume stability with the contraction
compensation by expansion.
5) As a result of the hydration material analysis, the generation of the ettringite by the
gypsum mixture is measured, and, accordingly, the long-term durability is secured with
the continuous hydration reaction.
Through this experiment, the EAFRS is considered as used for the inorganic binder, but
in order to use as the alternative binder of the OPC and regulated setting cement, it is
considered to require long-term durability review.
