Recycled Concrete at Elevated High Temperature Duration

Abstract:

Recycled concrete is the concrete mixed with crush aggregate recycled by waste concrete. This study investigates the effect of long term duration at high temperature on the mechanical properties and behavior of recycled concrete. The result shows that recycled concrete shrank after heating to temperatures below 500°C. Because the silicate aggregates expand over 573°C, recycled concrete expanded at 750°C. Recycled concrete contained the more recycled aggregates, the less expanded. The mechanical behavior of recycled concrete was worse than conventional concrete at treatments below 500°C. However, over 500oC, the resistivity of recycled concrete from construction sites, which contains some red brick, was better than conventional concrete. The property difference tends to decrease with elevated temperature.
