Title: Reducing Shrinkage Cracking of Structural Concrete Through the Use of Admixtures
PI: Tarun Naik
UWM Center for ByProducts Utilization
University of Wisconsin-Milwaukee
Project: The objective of this project is to evaluate five or more high-range water-reducing admixtures, including coal combustion products (CCPs), for suitability and effectiveness in reducing concrete cracking on bridge decks. Benefits expected of this research are improved concrete bridge deck mixture designs that will increase durability, reduce cracking, and ultimately reduce life-cycle costs and public inconvenience.
