Aggregates (Gradation Fundamentals) (60–90 min.)
Tues., May 31, 2016, at 12:00 PM (noon) CDT
Presenter: Gary Fick
This course focuses on the need for a good combined gradation of aggregates for concrete mixture optimization, and how that may be achieved. The course describes why a poor combined gradation can negatively impact the workability of concrete mixtures for paving applications. The webinar will also cover research efforts aimed at developing tools to evaluate concrete mixture workability, as well as resources that contractors can used in mixture proportioning. The course will also include tips and recommendations to assist contractors in adjusting mixture proportions in the field.
