Abstract: Conductive concrete is produced by addition of conductive filler to ordinary concrete. Electrically conductive concrete allows analysing stress and strain variation in structures by means of resistivity measurements. The study of self-sensing properties of conductive concrete is now of great importance to its application in civil engineering. Since there is very limited information about electrical properties of alkali-activated materials as alternative binders to Portland cement, this paper presents the study on basic electrical and self-sensing properties in compression of alkali-activated slag composite with carbon nanotubes as conductive filler. The results showed that addition of carbon nanotubes reduced the electrical resistance of alkali-activated slag, however, it did not improve its sensing properties.
