THE INFLUENCE OF TEMPERATURE ON FRACTURE ENERGY OF HYBRID FIBER REINFORCED CONCRETE

摘要：

The anti-fracture property of concrete container for nuclear waste was investigated to ensure its long-time durability. According to RILEM Standard the three-point-bending test was carried out by using the hybrid fiber reinforced concrctc(HFRC) and the plain high-strength concrete (PHSC) (SP-13) for comparison at normal temperature and 150℃respectively. Results show that the fracture energy of HFRC is 6.3～12.0 times higher than PHSC before heating and is 12.0～16.7 times higher than PHSC after the heating .The big-size steel fibers(Types A and C) are superior to both the small-size fibers (Types B) and polypropylene fibers in absorbing fracture energy, and the Types C steel fibers(shear-indented type) is superior to Type A(Shear-threaded type)and Type B(ultra-short/fine type)in improving the fracture energy.
