| 要旨 | Addition of polypropylene fiber was found to be effective in mitigating explosive spalling, a catastrophic failure mechanism inconsistently observed when high strength concrete was exposed to high temperature condition. However, melting of these fibers would degrade the properties of high strength concrete surviving from explosive spalling. Hybrid fibers were developed to mitigate explosive spalling and maintain the properties of heated high strength concrete. This paper presents the effect of hybrid fibers on fracture energy of high strength concrete after heat exposition. |
