Experimental study on the free expansion deformation of concrete during the cooling process after being heated to high temperature
Construction and Building Materials（2022）
Abstract
•The free expansion of concrete during cooling process was studied.•The linear expansion rate of concrete decreased with a decrease in temperature.•The coefficient of thermal expansion decreased with a decrease in temperature.•Residual deformation existed in concrete cooled from temperature above 400 °C.
