Heat, Water and Water Vapor Transport and Storage Properties of Alkali-Activated Aluminosilicates

Original language description

Alkali-activated aluminosilicates (AAA) are promising materials alternative to the cement-based ones due to high strength, very good chemical resistance and durability. As well as for cement-based materials, enhancement of electric properties of AAA allows to classify such materials not just as smart materials. AAA with enhanced electric properties by means of addition of sufficiently high amount of electrically conductive admixtures are promising in terms of self-heating or self-sensing ability. In case of self-heating composites, sufficient electrical conductivity is needed to increase ability to generate heat. Besides, thermal conductivity must be sufficiently high in order to effectively spread generated heat. However, the effective electrical conductivity and the effective thermal conductivity of AAA is significantly affected by amount of water present in pores. It is therefore important to experimentally determine heat, water and water vapour transport and accumulation properties. In this paper, thermal properties represented by the thermal conductivity and the specific heat capacity, hygric properties represented by the water absorption coefficient, the apparent moisture diffusivity, the water vapour diffusion coefficient, the water vapour resistance factor and sorption isotherm were investigated for the reference AAA and AAA electrically enhanced by carbon black (CB) in amount of 5.56 %.
