| Summary: | This study explored rheological and hardened-state properties of self-compacting alkali-activated concrete (SCAAC) incorporating ceramic tile powder waste (CPW) for construction activities. Samples containing 100% ground blast furnace slag (GBFS) were used as reference. Test data revealed that the mini-slump flow enhanced, while the plastic viscosity of SCAAC reduced when 50% or higher concentration of CPW was mixed with GBFS. Also, CPW affected the workability and plastic viscosity considerably when used in higher concentration. The strength decreased as GBFS substitution with CPW increased. In conclusion, the chemical structure, capacity and water assimilation of GBFS underpinned the rheological behaviour of SCCAC. |
