Mechanical activation of frozen lime putties
Original language description
The lime putty used for mortar preparation loses its desired properties, especially the plasticity and other rheological parameters, when it freezes. Two kinds of lime putty with 30 wt. % of solid content underwent 5 freeze/thaw cycles and their properties were investigated. Their consistency worsened dramatically after freezing. Mechanical activation was carried out by high-speed mixing of lime putty. This procedure led to a significant improvement in the lime putty plasticity and viscosity. The rheological parameters reached the original values that were determined before freezing. Rheological tests of lime putties were determined by rotational rheometer with the solids characterized by laser particle size analyzer.
