  • 1. Recognize and understand the basic technology

    behind self-consolidating concrete

    2. Evaluate the price and cost impacts on jobs using

    self-consolidating concretedesign, materials and

    placement

    3. Summarize the QC/QA aspects of self-consolidating

    concrete including durability and longer life

    expectancy of structures

    4. Develop a course of action to begin using self-

    consolidating concrete

  • SCC Definition - PCI

    A highly workable concrete that can flow

    through densely reinforced or complex

    structural elements under its own weight

    and adequately fill voids without

    segregation or excessive bleeding without

    the need for vibration.
