摘要
为了得到新型材料钢纤维RPC遮弹板的力学参数及接触爆炸性能参数,测试了5%纤维含量的试件的抗压强度、抗剪强度及断裂韧度,得到了多组试验数据。并对钢纤维RPC抗接触爆炸性能进行了初步的模型试验研究,根据试验数据及理论研究得到了它的爆炸压缩半径系数。通过两类试验表明,所采用的钢纤维RPC度件具有很高的强度与断裂韧度,其抗接触爆炸能力是普通混凝土的3倍左右。
In order to get mechanics parameters and contact explosion capability parameters,some RPC samples with 5% steel fiber were tested,many groups data were obtained with compressive strength,shear strength and fracture toughness.The model tests were carried out on RPC under contact explosion,the coefficient of explosion cavity radius of the material is obtained by above experiments and theory study.The two kinds of experiments above point out,RPC with steel fiber has very high strength and rupture temper and its capability anti-explosion is about three times higher than that of general concrete.
