Assessment of High Early Strength Limestone Blended Cement for Next Generation Transportation Structures
This research effort is aimed at evaluating the effects of increasing ground limestone addition rates and in particular high fineness blended cements developed for high early strength in precast concrete construction. Assessment of key material properties (e.g., setting time, strength development, shrinkage, creep, permeability) relevant to the construction, operation, and maintenance of transportation structures will be the focus. Results will be used to better understand the implications of changes in cement compositions and to provide guidance of how these changes can or should be accommodated in state and federal specifications for precast concrete elements intended for transportation structures.
