Abstract

Building materials with piezoresistive properties are used in smart structures for the self-sensing and self-monitoring applications. The electrical properties of such composites are influenced by their composition, amount and type of conductive admixture, but there is also an effect of external conditions such as temperature and moisture. This study presents an investigation of the effect of water saturation degree and moisture content on the self-sensing properties of cement-based and alkali-activated slag composites with graphite conductive filler in compression. The results show that alkali-activated slag exhibits better piezoresistive response compared to cement-based composite. The moisture content has a slightly negative influence on the self-sensing properties tested composites as the gage factor decreased with increasing amount of moisture content.
