Seven years after Self-Consolidating Concrete (SCC) was introduced to the American precast concrete industry we still see producers struggle with the basics of surface quality. Part of the initial draw of SCC is its improved surface quality; that is to say less defects due to entrapped air. Many producers have documented significant savings from more rapid, and effortless, casts after utilizing a stable SCC mixture in their production cycles, but fewer producers have documented savings from reduced repair labor and materials. For those that have invested time and effort into understanding what is necessary to achieve a defect free surface the payback has been more substantial that that of reduced casting times.
