    Dear Arun,

    The typical joining details at the junction of Column and beam is as shown as in the attached figure.

    The beam main bars shall be cranked near the columns and the crank length shall be 1: 4.

    In any case, the beam rebars shall not be passed from the outer of the column rebars which will compromise with the covers of the concrete.

    First of all, More than 21 popular brands of Steel available in India were tested as per IS codes by First Construction Council on the Infrastructure Quality, specially For India under GoI and State Government  Missions. Only six brands of Steel passed the tests – SAIL, RINL, Tata, JSPL, JSW, and Electrotherm.
    I have attached a Newspaper clipping for reference. If required, I can send you the test reports copy.

    Secondly, the prominent tests on Steel are physical and chemical.
    At the site, we can do some physical tests to ascertain some parameters of Steel, such as ductility, unit weight, and bending.

    As per IS 1786, the unit weight of the different dia of the Steel is mentioned and its variation too. Using that data, you can check the weight of the Steel available at the site.

    Further ductility, bend, and re-bend tests can also be carried out at the site. The procedure for the tests are mentioned in IS 1786.

    Note: These tests carried out at the site cannot be considered as final.  The tests must be carried by approved labs or institutes, and the reports given by them can be considered to gauge the quality of Steel.

    Dear VSR,

    The best suitable grade of cement for structural members such as columns and pillar depends upon the design. Which type of cement is considered at the time of the design of these structural members?
    For general construction, it is recommended to use 43-grade cement as the 53-grade cement is used for fast-paced construction, rapid setting and it requires proper care while curing.
    Grades of Ordinary Portland Cement-Based on IS Codes

    Either you use natural sand or M-sand, there is no such difference in the strength of the concrete.

    Lastly regarding the curing time, the curing period for any concrete member shall be 28days.
