    Rate this question:

  • 10. 

    Form supports for prestressed concrete members shall not be removed until sufficient ________ has been applied to enable prestressed members to carry their dead load and anticipated construction loads. 

    • A.

      Prestressing

    • B.

      Post tensioning

    • C.

      Curing

    • D.

      Force

    Correct Answer
    A. Prestressing
    Explanation
    Form supports for prestressed concrete members should not be removed until sufficient prestressing has been applied. This is critical to ensure that the prestressed concrete members have attained the necessary strength to support their own weight (dead load) and any additional loads that might occur during construction. Prestressing involves applying forces to the concrete to strengthen it against future service loads, thus making it essential before the removal of supports to avoid structural failure.

    Rate this question:

  • 11. 

    In reference to removal of forms, shores, and reshoring, sufficient strength shall be demonstrated by ________ _________ considering proposed loads, strength of forming and shoring system, and concrete strength data.

    Correct Answer
    D. Structural analysis
    Explanation
    PG. 74, 6.2.2.1

    Rate this question:

  • 12. 

    In reference to cold weather requirements all concrete materials and all reinforcement, forms, fillers, and ground with which concrete is to come in contact shall be free from ______. 

    • A.

      Ice

    • B.

      Heat

    • C.

      Water

    • D.

      Snow

    Correct Answer
    A. Ice
    Explanation
    During cold weather concreting, it is crucial to ensure that none of the materials involved, including reinforcement, forms, fillers, and ground, are coated with ice, frost, or snow. The presence of ice can severely affect the curing process of concrete, leading to weakened structures due to improper hydration of the cement. This is a standard requirement to maintain the integrity and strength of the concrete.

    Rate this question:

  • 13. 

    Conduits, pipes, and sleeves shall be permitted to be considered as replacing structurally in compression the displaced concrete provided they are of uncoated or galvanized iron or ______ not thinner than standard schedule 40 steel pipe.
