- Synopsis
- This paper describes test methods for fire spalling resistance of concrete and techniques for the assessment of concrete damage from fire, based on the findings of the Japan Concrete Institute's Research Committee on Performance Evaluation of Concrete Structures under Fire Conditions. Specifically, regarding test methods for are spalling resistance of concrete, this paper outlines the Committee's hdings regarding common tests conducted for the purpose of proposing a test method for fire spalling resistance of concrete (investigation parameters: specimen shape and size, test age, heating method, etc.), and it introduces the concrete spalling resistance test method proposed by the Committee as a draft proposal. Regarding techniques for the assessment of concrete damage from fire, findings regarding post-fire assessment of concrete are summarized based on the results of common tests consisting of chemical analysis and non-destructive/semi-destructive testing of test specimens fabricated to simulate fire-damaged concrete.
