Abstract:
The p-x-t relational model was established based on the calculating model of concrete filter carbonization accelerated by wind pressure and relationship between wind pressure and time or depth. The carbonization depth was calculated in examples. A simple way was provided to calculate the concrete carbonization depth. In order to validate the effect of concrete carbonization accelerated by wind pressure, Π type concrete beam carbonization experiment was carried out. According to the theoretical analysis and experimental results, it is concluded that the wind swirl and the fosse moat effect can also accelerate the concrete carbonization. Besides, wind pressure can generate secondary air field, which can also accelerate the concrete carbonization. The principle of concrete carbonization accelerated by wind pressure is perfected.
