钢纤维石墨导电混凝土比热的试验研究

摘要

Conductive concrete is manufactured using steel fibers and graphites as additives. The specific heat as a very important property of the conductive concrete is studied. The specific heats of 23 sets of conductive concrete contain-ing different component of mixture are tested. The results show that there are some differences between the result of exper-iment and that from the weighted mean method. Based on the experimental result, the correction formula of the weighted mean method for evaluation the specific heat of conductive concrete is put forward.%选择目前常用的导电材料钢纤维与石墨制作了23组导电混凝土，研究了单独掺加钢纤维、石墨以及混合掺加钢纤维石墨导电混凝土的比热，给出导电混凝土比热的取值范围。结果表明，加权平均法的计算结果与试验结果存在一定的差异，在试验结果与加权平均法的基础上，给出了导电混凝土比热计算的修正公式。
