  • Rheological and mechanical properties of mortars

    The small-strain stiffness of hardened wet-flow mortars is controlled by the paste stiffness, as the paste fills the voids and conceals the properties of grains (shape and mineralogy) on small-strain measurements. • The loosest packing density of the fine aggregate e max depends on particle shape. Therefore, a larger volume of paste will be ...
