【 摘 要 】

The paper discusses basic properties of mineral binders containing calcined water treatment sludge (WTS). The supplementary waste material was dried at 105°C and subjected to calcination at high temperatures of 400, 600 and 800°C for a constant time. Chemical composition was determined and pozzolanic activity was measured using the Chapelle test. Moreover, standard consistency, setting time and mechanical properties of cementitious binders containing 25% and 50% of calcined sludge were determined. The test results presented indicate that water treatment sludge calcined at 800°C exhibits high pozzolanic activity and can be considered a promising ingredient of cement-based mineral binders.
