Title: Assessing Fire-Damaged Concrete
Author(s): M. A. Riley
Publication: Concrete International
Appears on pages(s): 60-63
Keywords: buildings; concretes; cracking; fires; fire tests; high temperature; isotropy; petrography; General
Abstract:Five flint-aggregate concrete cores taken from existing structures were heated to temperatures exceeding 800 C for two hours, and the final stabilized temperature profile was determined for each specimen. Thin sections were taken longitudinally along the diameter of each specimen and analyzed petrographically. Specific petrographic features were correlated with temperature profiles. Results indicate that thin-section petrography may be useful in determining the temperatures developed in concrete exposed to fire.
