摘要
采用复合技术制备了两种强度等级的超高性能钢纤维混凝土(UHPSFRC),对6块靶体进行了抗一次和抗二次接触爆炸试验,对比分析了靶体材料的抗爆炸性能.结果表明,制备的超高性能钢纤维混凝土具有优异的抗一次和抗二次爆炸性能.对压缩系数进行了计算分析,建议超高性能钢纤维混凝土(有粗骨料)CF150的压缩系数取为0.112,超高性能钢纤维混凝土(无粗骨料)CF200取为0.096,且CF200的抗二次爆炸压缩系数要降低到80%左右.
Two kinds of ultra-high performance steel fiber reinforced concrete （UHPSFRC） were prepared by composite technology to improve the compressive strength of concrete used in defense works and its anti-repeat-strike ability. Six tests on concrete targets under one time explosion and second explosion were performed and the characteristics were analyzed. The results indicated that the materials prepared had remarkable anti-one-time-explosion and anti-second-time-explosion. The explosive compression coefficients were computed and it was found that the explosion compression coefficients of CF150 and CF200 were 0.112 and 0. 096 respectively. The explosive compression coefficients of CF200 under the second explosion were reduced to 80%.
