Abstract
While heat curing is mostly used in the precast concrete industry, freshly cast insitu concretes can
also potentially attain high temperatures even without artificial heat application. The demands of
the modern construction industry coupled with advances in cement manufacture promote the use of
high early strength cements and high cement contents. These factors in addition to hot weather
conditions in tropical countries, and large concrete pours may raise concrete temperatures to levels
similar to those of heat cured concretes.
This article attempts to give an overview of the modern application of heat curing practice,
discusses problems associated with exposing concretes to undesireably high temperatures at an
early age. Current needs and recent developments associated with delayed ettringite formation are
highlighted while potential future advancements are speculated.
