Self-consolidating concrete has become commonplace in
the North American precast industry over the past two decades. Production and quality control personnel have responded overwhelmingly to the need to tighten tolerances and closely monitor materials and practices during the casting of SCC. However, many producers still struggle with some issues associated with SCC. This course will tackle several common issues which producers face while batching and placing SCC. We will identify causes and solutions for issues such as bug holes, occasional segregation, pour lines, low strength and low slump flow. Participants will learn to troubleshoot their SCC mixes and production practices.
At the conclusion of this webinar, you will be able to:
- Calculate combined aggregate gradation and recognize how changes in gradation will affect your mix performance
- Recognize causes of several surface defect conditions and how to adjust for them
- Identify the effects that various batching and casting procedures have on the surface aesthetics of SCC
