Influence of Water Content and Mixing Conditions on the Properties of Lime-Based Materials

Blog Article

This paper evaluates the influence of water content and mixing conditions (mixing time and sequence of addition sharps honda of the constituents) on the fresh state properties of lime-based materials and their impact on the hardened state properties.Higher water contents allowed an increased fluidity and lower torque, yield stress and plastic viscosity values.In turn, a longer mixing time with the aggregate caused a progressively stiffer mortar and a substantial increase in the torque, yield stress and plastic viscosity values due to the breakdown of lime agglomerates that consume part of the free water available to lubricate the mix.A longer mixing time without the aggregate caused similar trends, albeit to a much lesser extent.The water content and mixing conditions also had a major impact on the resulting porous structure of lime mortars and, thus, smartgiro on their mechanical strength.
