Abstract: 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 containing different component of mixture are tested. The results show that there are some differences between the result of experiment 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.
