selfconsolidating lightweight concrete incorporating

Chapter 4: Construction Details, Section 90: Concrete

Self-consolidating concrete (SCC) is defined as flowing concrete that is capable of spreading to a level state without segregation and without the use of internal or external vibration. The general provisions of Section 90-1, "General," of the Standard Specifications apply to self-consolidating concrete unless otherwise specified.
