Abstract:This paper explains the concept of water sorptivity as a measure of concrete quality and discusses the effect of interrupted curing (as distinct from continuous curing) on the quality of concrete. Results of a pilot study on concretes incorporating ground granulated blast-furnace slag either as a blend or as an intergrind are presented. It was found that the response to interrupted curing varied depending on the constituents of the concrete. Plain concrete (i.e. without chemical or mineral admixtures) with a 28-day strength of 28 MPa showed a very slow response to interrupted curing, but could be improved by the incorporation of slag or by specifying a higher 28-day strength.
