摘   要：设计研发了一种新型的双层不锈钢纤维（DSSF）导电混凝土，该新型混凝土是一种多层结构，在2个不同的层中放置不锈钢纤维，用石墨颗粒或钢纤维对混凝土基体进行改性，并对其进行了抗压、抗弯拉及导电性能试验。结果表明，不锈钢纤维体积掺量为0.5%时，DSSF混凝土的抗压强度相对于素混凝土提高12%左右，抗弯拉强度相对于素混凝土提高26.92%。掺入不锈钢纤维及适量石墨颗粒后的DSSF混凝土其电阻率较素混凝土有数量级的减小。

Abstract: A new type of electrically conductive concrete with double-layered stainless steel fiber (DSSF) has been designed and developed. The concrete is designed as a multi-layer structure consists of two separate layers in stainless steel fibers. Graphite particles or steel fibers are used to modify the concrete matrix, compressive strength, bending tensile strength and conductive property are carried out on it. The results show that, compressive strength of DSSF concrete is increased by about 12% compared with that of plain concrete when volume content of stainless steel fiber is 0.5%, and the bending tensile strength of concrete is increased by 26.92% compared with that of plain concrete. The resistivity of DSSF concrete with stainless steel fiber and the amount of graphite particles is reduced by an order of magnitude compared with that of plain concrete.
