High temperature cement raw meal flowability
The flowability of cement raw meal is investigated at temperatures up to 850 °C in a specially designed monoaxial shear tester. Consolidation stresses of 0.94, 1.87 and 2.79 kPa are applied. The results show that the flowability is reduced as temperature is increased above 550 °C, indicated by increasing unconfined yield strength and reduced flowability factors. Deviation and reproducibility are acceptable for all temperatures except for 850 °C where belite formation and possibly calcination sinter the raw meal.
