Improving the performance of concrete using 3D fibres

摘要: This paper examines whether 3D fibre reinforcement can improve the toughness and flexural strength of concrete, when compared to equal dosage straight steel fibres. work was carried out determine structural qualities that may lead potential enhanced performance concrete is subjected a bomb blast in addition same act as safety measure earthquake situations. The majority injuries caused from attacks are result fragmented building components energised by wave, therefore it vital reduce fragmentation concrete. It known increasing energy absorption. A three point beam test conducted on two batches beams reinforced with fibres respectively, so post crack could be calculated compared. paired comparison between were also embedded cubes, pull testing for types. samples proved have higher than samples. had much value. After testing, continued span rupture plane after initial formation during 3 bend which held together matrix. These findings suggest would perform better protection material results show produce tougher hold fragments loading.
