Steve Gillen, Illinois Tollway
This research project will consist of a detailed lab analysis of concrete mixes containing steel slag RAP aggregates to determine if the expansive nature of the steel slag in these mixes will have impact on the performance of concrete mixes containing slag. Any benefit to the Tollway can only occur if the study finds the expansion of steel slag aggregates to be minimal and not jeopardize the life of the concrete. If slag containing RAP can be used in concrete, economic and sustainability benefits will result.
