| Outline of Final Research Achievements |
To investigate the applicability of slurry infiltrated fiber concrete (SIFCON) for use in blast-resistant structures, experimental investigations were conducted to evaluate the spall-reducing performance of SIFCON subjected to contact detonation. The test results showed that SIFCON was more effective in reducing spall damage due to contact detonation as compared with normal concrete and other various fiber reinforced cementitious composites. Based on the test results, we identified the spall and perforation limits of SIFCON slabs subjected to contact detonation. Further, it was also shown that the spall-reducing performance of reinforced concrete (RC) slabs could be remarkably raised by replacing the concrete near the rear side of the RC slab with the SIFCON.
