The Role of Aging on Rheological Properties of Lime Putty

The role of aging on rheological properties of lime putties was investigated by rotational rheometry, scanning electron microscopy and particle size distribution analyzes. Disaggregation of large clusters during aging and resulting microstructural enrichment of micron-sized particles was found to be one of the possible reasons for the continuous increment of plasticity and yield stress of lime putties during long-term aging. The extent of thixotropic and rheopectic behavior is affected by both calcination process and microstructure development during aging.
