21. Effects of the Test Conditions and Mixture Proportions on Behavior of High-Strength Concrete Exposed to High Temperatures
Published: 2/1/2002
Authors: Long Thanh Phan, Nicholas J. Carino
Abstract: Mechanical properties of high-strength concrete exposed to elevated temperatures were measured by heating 100 mm x 200 mm cylinders at 5 degrees C/min to temperatures of up to 600 C. Heating was carried out with and without a sustained stress, and pr ...
