Fine limestone additions to regulate setting in high volume fly ash mixtures (2012, methodology): “Setting time and isothermal calorimetry curves for pastes were supplemented by measurement of early and later age compressive strengths of mortar cubes, to assure that no detrimental effects on strength were produced.”
Effects of colloidal nanosilica on rheological and mechanical properties of fly ash–cement mortar (2013, background): “However, delays in early-age strength gain and setting times are considered to be major drawbacks [2–4].”
Optimization of cement and fly ash particle sizes to produce sustainable concretes (2011, background): “Table 3 Measured fresh properties of mortar mixtures. measurements on cement pastes prepared in a high shear blender, but with the following modification to better prevent any evaporation from the specimen during the course of the test [21].”
Hydration and strength development in ternary portland cement blends containing limestone and fly ash or metakaolin (2013, methodology): “For this reason, fine limestone powder has been used to limit delays in setting in high volume fly ash mixtures [13].”
