| Title: | Detecting Deleterious Fine Particles in Concrete Aggregates and Defining Their Impact | |
| PI: | Steven M. Cramer Department of Civil and Environmental Engineering University of Wisconsin-Madison |
|
| Project: | The objectives of the research are to: 1) Develop a rapid test to detect clay particles in aggregate sources that is both indicative of their quantity and their physical and chemical nature. This is intended to indicate whether these clays are harmful or innocuous. 2) Quantify the impact of total (from combined coarse and fine aggregates) clay content on concrete strength development, shrinkage and porosity. Advance a fundamental knowledge of the role of clays in concrete performance so that mitigation strategies can be formed in future research. 3) Quantify clay content from several Wisconsin sources of aggregates to determine the relative contribution of clay fines from coarse aggregates and from fine aggregates. |
