SHORT TERM STEAM-CURING AND CONCRETE LATER-AGE STRENGTH

The effect of steam curing on the later strength of concrete was studied on mixtures having a nominal cement content from 150 to 400 kg/m3. Three series of tests were carried out, during which after 30 or 60 minutes curing time varied from 2 to 5 hours and the curing temperature varied from 60 to 80 deg C. The tests have confirmed that steam affects the later strength of concrete. However it was concluded that for short curing periods at moderate temperatures, this negative effect is mainly due to a defect in curing related to the moisture content and not necessarily to physical parameters such as increased porosity, internal cracking or heterogeneity of the paste. Under these conditions it was established that an additional time of 7 days in a humid atmosphere was necessary to eliminate the adverse effects of steam curing on concrete strength.
