| Abstract: | The damage characteristics of fire concrete and the features and liminations of the traditional methods for testing fire-damaged concrete were analysed. Several latest technologies for testing fire-damaged concrete, such as colour image analysis, fire behaviour test, infrared thermal image, thermoluminescence test and electrochemical test, and their principles, advantages and applications were systematically reviewed.The possible study trend of testing technology for fire-damaged concrete was forecasted. |
