    Very important question before providing clearances to pour concrete. I would follow following steps.

    1. Ensure Contractor has bar bending schedule and approved drawing.
    2. Ensure reinforcement used are approved grade and test certificates are in place.
    3. Check  diameter of rebar ( reinforcement)
    4. Check spacing
    5. Check banding radius
    6. Check number of bars
    7. Check laps are of proper length. Some time couplers are used to join the reinforcement. Couplers must be approved.
    8. Check proper cover to rebar is in place.
    9. Covers should be approved
    10. Check the reinforcement installed does not sag  or move. For this ensure you use chairs.
    11. Tie the rebars together using soft annealed lining wire and turn the know inside.
    12. Reinforcement must be clean without any dirt or coating.
    13. Some time special reinforcement steel is provided around openings. Ensure this is in place.
    14. It is normal for QC departments to use check lists for this.

    Hope this helps.

    There is a minor difference between ground beams and capping beams Ground Beams are provided between the pile caps, it provides structural stability and provide strength to a foundation While Capping Beams ties all piles together and helps to distribute load of superstructure to the substructure. It has the same function as pile caps, in addition to distribute the load of the superstructure.

    The most active part of cement is the material finer than 10-15 nanometer. Furthermore, a fine grind of cement clinker is able to coat the surfaces of aggregates more completely than coarse material enabling intimate contact of the resultant paste or mortar.

    Gypsum is work as a starting agent as well as it restricts soundness in the cement.

    Apart from gypsum of various admixtures already listed in some previous post.

    The chemical name of gypsum is calcium sulphate.

    Thank you.

    Yes, you can do that. These are called hung columns. These are columns, having no foundation/ footing, rest over beams, or slabs. These are also termed as hanging columns/ floating column.

    1. Yes, you can do that. These are called hung columns. These are columns, having no foundation/ footing, rest over beams, or slabs. These are also termed as hanging columns/ floating column.
    2. They can not transfer load directly to the foundation or footing. Load from these columns is the point load on the beam over which it rests.These beams are generally deep beam need high percentage of reinforcement, also termed as transfer beam. Load is transferred through the transfer beam to the supporting columns, ultimately to the foundation.
    3. These columns are designed to take vertical load , considering it a compression member.
    4. These are abundantly provided to get more space in the ground floor to keep provisions for parking, conference hall, architectural requirement , banquet hall in hotels, commercial building etc.These are also provided in intermediate floor for the similar purpose.
    5. These columns are designed for vertical load only. In earthquake prone areas these may prove unsafe. If at all provided, they will not take lateral forces, all seismic forces shall be taken by the main columns supporting the transfer beam.
    6. Reinforcement detailing is an important issue in the design of column- beam junction.
