Abstract
A high-strength concrete with silica fume was placed in the full-scale model column specimens and temperature histories and core compressive strengths were determined. Laboratory-scale specimens were prepared with the same concrete and their temperature histories and compressive strengths were compared with those of model columns. Effects of testing parameters, such as the number of specimen in an adiabatic curing chamber, thickness of thermal insulation of specimen jacket and the duration of curing, on the temperature history and compressive strength were discussed. The effects of the number of specimen in a chamber and the thickness of insulation on the maximum temperature and temperature increasing rate were found to be significant but insensitive to 28 and 91-day compressive strengths.
