Abstract: A method is for manufacturing elements including hydraulic binder and aggregates. The method includes mixing a dry mortar composition including hydraulic binder and aggregates with water, to form a wet mortar. The method also includes pumping and conveying the wet mortar towards an outlet. During the conveying at least two physical properties of the wet mortar are measured on-line. The physical properties include viscosity and at least one of flow and density.

Abstract: A system implements a manufacturing method of construction elements including hydraulic binder and aggregates. The system includes a mixing device adapted to mix a dry mortar composition including hydraulic binders and aggregates with water, to form a wet mortar, an outlet, a pumping device adapted to pump and convey the wet mortar towards the outlet, and at least one sensor adapted to measure on-line at least two physical properties of the wet mortar on its way from the mixing device to the outlet, the physical properties including viscosity and at least one of flow and density.
