【摘要】 对混凝土中掺加不同体积百分含量的碳纤维、不同掺量和不同细度的水淬钢渣对混凝土的抗渗性能、抗冻性能等耐久性及干缩变形特性的影响进行了研究。结果表明:超细钢渣和碳纤维在一定掺量范围内可提高混凝土的抗渗性能和抗冻性能;在渣灰比相同的情况下,抗渗性能随钢渣细度的增大逐渐提高;钢渣-碳纤维复合导电混凝土的干缩值要略大于普通混凝土。更多还原

【Abstract】 It is studied that the effects on anti-permeability,frost resistance,durability and dry shrinkage deformation of concrete by adding different volume percentage contents of carbon fibre,different content and fineness of granulated slag.The results show that ultrafine slag and carbon fibre can improve the anti-permeability and frost resistance of concrete within a fixed content range,under the same ratio of slag and ash,anti-permeability can be improved gradually with the increased fineness of slag,the dry shrinkage value of slag-carbon fibre multiphase electric conduction concrete is slightly larger than that of an ordinary concrete.更多还原
