WebSelf-consolidating Concrete (SCC) SCC has very high flow; therefore, it is self-leveling, eliminating the need for vibration. Due to the superplasiticizers used—chemical admixtures that impart very high flow—SCC exhibits very high compaction as a result of its low air content. Consequently, SCC can have very high strengths, exceeding 50 MPa. WebThe flow value is recorded in 0.25 mm (0.01 inch) increments at the same time the maximum load is recorded. Figure 2.
