要旨 |
The effect of replacement dosage and specific surface area of limestone powder and their interactions with various mixture parameters on the rheological behavior of highly-flowable mortar was investigated using a statistical experimental design. The derived mathematical models indicate that the slump flow, V-funnel flow time, yield stress, and plastic viscosity are highly influenced by the replacement dosage and specific surface area of limestone, the water-to-cementitious materials ratio, the high-range water-reducer percentage, the sand volume, and various interactions of these parameters. Comparisons between predicted and measured properties confirm the good accuracy of the established models. |
