    Study Notes

    Slab Types

    • One way slab, two way slab, flat plate, and flat slab are types of slab constructions.
    • Wafer slab is another type of slab construction.

    Concrete Properties

    • Concrete is a versatile material that can change from liquid to solid form.
    • Concrete hardens due to chemical reactions.

    Beam and Slab

    • In a cantilever beam, more reinforcement bars are installed at the top (A. Top Bars) where the shearing of the beam occurs.

    Steel Reinforcements

    • Steel reinforcements have different grades based on tension:
      • Grade 40 – 40,000 psi
      • Grade 60 – 60,000 psi

    Advance Slab Types

    • Advance construction methods include:
      • Lift slab
      • Slip form (vertical and horizontal)
      • Flying form

    Spanstress Floor System

    • The Spanstress floor system is a type of floor construction.

    Building Technology

    • Building technology involves the study of construction methods and materials.
