Why is propping required for long structures once the formwork is removed?

    When the sufficient strength is attained for the long span concrete structures to support their self weight, creep deflection may occur in these structures if propping is not provided after the removal of formwork.

    When the sufficient strength is attained for the long span concrete structures to support their self weight, creep deflection may occur in these structures if propping is not provided after the removal of formwork. Hence repropping is carried out after removing formwork and thus these props should not be allowed to stand too long because creep loads may overstress them.

    There are many advantages of using plastic formwork over wooden formwork but the main advantage is we can handle plastic formwork very easily rather than handling wooden formwork because plastic formwork has light weight. Also plastic formwork is good resistant against water. And any type of complexRead more

    Rebate is a top edge cut on the stone so that it does not allow the rainwater to penetrate inside the stone mortar or joint and flows quickly from the horizontal surface of stone masonry. Throating is a groove provided inside the cornice, sill, and coping to prevent water flows with the wall surfaceRead more

    Rebate is a top edge cut on the stone so that it does not allow the rainwater to penetrate inside the stone mortar or joint and flows quickly from the horizontal surface of stone masonry.

    Throating is a groove provided inside the cornice, sill, and coping to prevent water flows with the wall surface and allows it to discharge away from the wall surface. It protects walls from the impact of rainwater.

    Chases is a stones course provided at the top of the wall. It also protects from rainwater. It is generally constructed in an ornamental design.

    Rigid pavements because of their nature, allow for a larger variation in subgrade material (in terms of strength), unlike flexible pavements.

    Rigid pavements because of their nature, allow for a larger variation in subgrade material (in terms of strength), unlike flexible pavements. That is why rigid pavements can be built over almost any kind of soils with appropriate ground improvement.

    The general range for CBR is 2% to 14% or 15%. If it is found below 6%, then the code specifies some necessary subgrade improvement before laying the concrete slab directly over it.

    Also, the CBR could be increased up to say 40% or 50% by ground improvement, and still, the subgrade may be fit for rigid pavements.
