Evaluation of self-sensing and energy harvesting potential of multifunctional alkali-activated metashale mortar
Original language description
Sustainable construction materials with new functional properties can be beneficially used in special civil engineering applications. Since geopolymers are of lower negative environmental impact in comparison with cementitious materials and possess favorable material properties (mechanical performance, durability, chemical and high-temperature resistance), they are good candidates for optimization of electrical properties by doping with electrically conductive admixtures, which is the presumption of resistance heating or thermoelectric energy harvesting function. The research presented in the paper dealt with the design of geopolymer mortar based on (potassium hydroxide/silicate)-activated metashale doped by a mix of carbon fibers and graphite powder. Material characterization revealed promising properties for the self-heating function (l = 1.06 W.m-1·K-1, e = 8.7 x 10-1 S·m-1) which was confirmed by AC self-heating experiment (30 V RMS). Thermoelectric experiment revealed non-linear thermoelectric voltage dependence on dT, and maximum of the P-Type Seebeck coefficient (heating: 343.56 µV·K-1, cooling: 312.50 µV·K-1) corresponding to ZT values of 4.20 x 10-5 and 2.75 x 10-5 in dT range of 140 K.
