Abstract

The rheology of a series of mortars made with natural hydraulic limes (NHLs) from four manufacturers, commercially available in the UK, in conjunction with two Scottish sands, was determined. Rheologically, mortars conform to the Bingham model and the yield stress and plastic viscosity vary significantly between the various NHLs. As a consequence, when used on site, the water content necessary to achieve a consistent rheology varies over a two-fold range. Since site workers adjust water content to achieve a consistent rheology, this range will have a serious effect on the properties and performance of the hardened mortar in service.
