要旨 |
Both laboratory and in-situ tests were carried out using normal concrete (NC) and the one having a high amount of ground granulated blast furnace slag in the binder (BC) to study the evolution of apparent coefficient of thermal expansion (CTE), which yielded a three-stage development for early-age concrete. The laboratory test showed that NC had similar apparent CTEs at stage II and III due to insignificant variation of internal relative humidity (RH), while BC had a further drop at stage III related to a pronounced RH reduction. The in-situ test showed more deviation in NC than in BC. |
