Effect of graphite filler on crack initiation of alkali-activated slag based composites
Original language description
The alkali-activated slag (AAS) is an alternative building material to ordinary Portland cement (OPC) based materials. The mechanical properties and application possibilities of AAS are very similar to OPC based materials. This type of material is effective in reducing CO2 emissions and energy consumption (Keun-Hyeok et al.). Addition of graphite powder increases its electric conductivity, hence, introducing new functionality to building materials such as self-sensing and self-heating properties. In this study, the effect of graphite filler on the crack initiation of alkali-activated slag composite is investigated. The graphite powder was added in the amount of 5, 10 and 15% with respect to the slag mass. Beam specimens with an initial stress concentrator were tested in three-point bending at the age of 28 days. The load versus crack mouth opening displacement (F–CMOD) diagrams were recorded during the fracture tests and evaluated using the Double-K fracture model (Kumar and Barai). This model allows
