Abstract: An experimental study on the thermal and mechanical properties of steel-fiber-reinforced concrete for solar/thermal energy storage purposes is presented in this report. It takes into account the results of measurements of thermal conductivity, thermal resistivity, thermal diffusivity and the results of compressive strength as well as thermal energy storage calculated from the knowledge of the above measured parameters. The Experimental testing method is described as well based upon the linear heat source theory, it requires the use of a special probe to be inserted into the sample. The experimental programme was forwarded to test concrete aggregate mixtures with three different sizes of steel fibers and one plain concrete. The measurements were carried out from the pouring time of cubic samples and were ended up when hardened conditions were achieved. The results indicate that the steel fibers have influence on the thermal properties of the concretes tested.
