Hygro-thermo-electrical modeling of transport phenomena in aluminosilicate composites
Original language description
Alkali-activated building materials with sufficiently high electrical conductivity are able to generate Joule heat which can be utilized in practical applications, e.g. for construction of heating elements incorporated to pavements, roads or bridges. Convenient electric properties of such materials are usually achieved by addition of a sufficient amount of electrically conductive admixtures to the reference material. Situation is relatively simple in case of dry materials: electrical conductivity and therefore heating ability is influenced just by electron charge carriers. However, thermal and electric properties of porous materials partially or fully saturated are significantly affected by water present in porous structure. With increasing amount of water, the effective electrical conductivity and the effective thermal conductivity increases with increasing amount of water due to substitution of air present in pores in dry state by water in partially or fully saturated state. Therefore, model taking into consideration coupled transport of mass, heat and electric charge needs to be used to assess heating ability of wet porous materials influenced by external electric voltage. In this paper, such model is outlined in theoretical way.
