“…Internal curing promotes hydration of cement by supplying water from the inside by using internal curing materials with high water absorption. Water-absorbing polymer and artificial lightweight aggregate are used as internal curing materials [4,5]. In addition to these two conventional internal curing materials, roof-tile waste aggregate has been also investigated as an internal curing material.…”

The purpose of this study is to quantitatively evaluate the effects of steam curing and internal curing on contribution of fly ash to strength development of mortar by using cementing efficiency factor (k-value) that represents strength development performance as a binder of fly ash. In addition, the pozzolanic reaction of fly ash was evaluated from the viewpoint of calcium hydroxide consumption by using thermogravimetry and differential thermal analysis as well as the degree of fly ash reaction by using selective dissolution method. The result indicated that steam curing improved early compressive strength and internal curing improved compressive strength and k-value at all ages. Also, a linearrelationship between the degree of fly ash reaction and the k-value was shown regardless of the age and the replacement ratio of fly ash.
