WebReinforced Concrete Pipe. Modern reinforced concrete pipe is manufactured using state of the art machinery, providing a high strength, resilient, dependable product designed to … 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.
