The grout flows into one end of the channel. Rheology Melment is used to control water demand and improve the workability of construction and industrial products based on hydraulic cement and gypsum. Workability is a complex system of two critical properties, consistency and homogeneity, that must be balanced to achieve optimum functionality of the grout, mortar, plaster or concrete. Workability Workability is a complex system of two critical properties, consistency and homogeneity, that must be balanced to achieve optimum functionality of the concrete, grout, mortar or plaster. We measure consistency with devices such as the slump cone, flow cone, flow table and flow channel.
Consistency is a measurement of one dimension of workability.
It does not indicate whether or not a low viscosity grout has the cohesion to be placed without segregation and bleed. Different grouts with the same consistency can have different workability characteristics. Melment improves consistency by dispersing the cement and reducing the viscosity of the cement paste. To measure a grouts homogeneous properties it is necessary to use a rheometer, an instrument that measures yield stress and plastic viscosity. Melment reduces viscosity, increases flow and improves consistency.
