    Eight major pts:

    • Manufacturer Certificate
    1. Grade of steel
    2. Ultimate & bearing strength of steel
    • Length of Bar
    1. Std length = 12m.
    • Wt of bar
    1. Using formula, W = (DxD)/162 kg/m
    2. For 10mm dia, W = (10×10)/162 = 0.617 kg/m
    • Dia of Bar
    1. Randomly check the dia of bar using “Vernier Caliper” from each lots of diff dia.
    • Tag on Bar
    1. ISI Mark
    2. Grade of Steel
    3. Company logo/Name
    • Color of Bar
    1. Should be grey & not any rusted color.
    • Bend Test
    1. Bend the bar at 180° & observe the behavior of the rebar.
    • Re-Bend Test
    1. Bend the bar at 135° & observe the behavior of the rebar.
    2. Place it in 100°C hot water for 30 mins. Then bend at 157.5° & observe the behavior of the rebar.

    Most imp’ly, the bars should have grips on it.

    Difference between granular sub-base and wet mix macadam in payment structure:

    The wet mix macadam mostly consists of laying spreading and compacting of clean, crushed, well-graded granular material that is prepared and approved granular sub-base.

    Single compacted wet mix macadam player shall not be less than 75mm.

    Whenever we are using vibrating compacting equipment then compacted depth of a single layer of the course of the subway may be up to 200 mm.

    Wet mix macadam shall be prepared in an approved of water macadam mixing plant.

    Here replacing the aggregate fraction should be retained on 22.4 mm sieve with materials of passing from 22.4 and written on 4.75 mm.

    While the addition of water, the evaporation loss shall be considered the mixed material shall be uniformly wet and segregation will take place.

    Sites of Special Scientific Interest give legal protection to the best sites for wildlife and geology in England and Wales. They are the areas of land that Natural England Resources Wales designate as being of special interest because of their flora, geological or physiographical features, such as wetlands, rivers, meadows, beaches and peat bogs.

    The consideration must be made are as follows :-

    – Proper planning should be done.
    – The approval should be needed.
    – Land should be surveyed and all the test should be performed.

    Hi,

    The prestressing steel used for prestressed concrete can take the form of

    1. Tendons
    2. Cables
    3. Wires – (Plain wire and Indented Wire)
    4. Strands –(Two-wire, three-wire and seven-wire strand)
    5. Bars

    The types of prestressing steel are:

    1. Cold Worked Prestressing steel
    2. Stress-relieving prestressing steel
    3. Strain tempered Prestressing steel

    Difference between Reinforcing Steel and Prestressing Steel

    Both R.C.C and Prestressed Concrete employs steel bars or wires in order to sustain tension. But both the types of concrete make use of different steel.

    The steel used by R.C.C concrete can be:

    1. Solid Bars with Ribs
    2. Wires
    3. Metal Mesh

    The steel used in Prestressed Concrete are wires, strands, solid bars as mentioned above. Prestressed concrete uses high tensile strength steel that is manufactured by increasing the carbon content in steel compared to ordinary mild steel used in R.C.C.

    In prestressed concrete, the steel used is tensioned or prestressed. This results in loss of prestress in a range of about 20%. The use of mild steel bars or HYSD bars bring a greater loss than this value. Hence, it is necessary to have high strength tensile bars for prestressed concrete.
