Abstract: Rheology of high flow mortar and concrete was studied using coaxial cylinder rheometer and lifting sphere viscometer.
The tests results were compared with the traditional test methods of high flowing mortar and concrete.
Generalized equations for viscosity and yield stress of the mortar and concrete were then developed based on this investigation.
The Farris model was used to calculate the viscosity and a new model was proposed to calculate the yield stress for the generalized equations.
These models were validated using test results of different high flow mortar and concrete.
The study also revealed that the rheology values obtained using the coaxial cylinder rheometer and lifting sphere viscometer test are significantly different.
