The method to measure the plastic viscosity of cement paste

In the previous post, I introduced the protocol to measure the yield stress of cement paste. I would like to share the method how to measure the plastic viscosity of cement paste. The principle determine the plastic viscosity of cement paste is using the relationship between shear rate and shear stress. Applying a serials of […]

The right protocol to measure yield stress of cement paste

The rheology of cementitious material paste is complex and difficult to be investigated. One value of rheology is yield stress. The best method to measure the yield stress in laboratory is using the vane method. However, there is no much literature reporting an practical and detailed testing protocol to measure the yield stress of cement […]
