    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.

    Though self compacting concrete is used, these bulbs may not be filled completely. So, reinforcement is lowered after concreting, after clearing the muck on top, if any, either by vibration or driving, so that concrete is forced into the bulb.

    Reinforcements used in the process of prestressing:

    Especially in case of prestressing, we are using strands of Steel and it’s called tendons.

    Tendons are made of high strength Steel.

    Three major types of reinforcements which are used in Prestressing:

    1. Spalling R/f
    2. Equilibrium R/f
    3. Bursting R/f

    Combination of reducing the structural thickness reduced conventional reinforcements quantities and fast construction often results in un prestressed structure.

    Thank You.

    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.
