    There are certain methods to remove the delaminated concrete, and then formwork is to be fixe. After that, the application of repair material like a dry pack, and wet pack, shotcrete, is carried out if reinforcement is not removed while fixing the pipe.

    You can try one other method also, by fixing plate bonding in the beam on the bottom to enhance the flexural strength, you will have to rest the plate on the bricks, and for that, you will have to remove the top layer of the brick. You also may need to provide scaffolding if you are altering the load-bearing wall. As it is a load-bearing structure, if any alteration is done in the load-bearing wall, it should be done with the consultation of a structural engineer.

    As we know 1:2:4 ratio is for M15 concrete. Generally Water quantity is calculated as per below formula: Water Quantity=W/C ratio*Cement Quantity Generally W/C ratio is lays between 0.4 to 0.6 as per IS 10262(2009). Now first we have to assume cement quantity, so let's assume cement quantity=50 KG aRead more

    As we know 1:2:4 ratio is for M15 concrete. Generally Water quantity is calculated as per below formula:

    Water Quantity=W/C ratio*Cement Quantity

    Generally W/C ratio is lays between 0.4 to 0.6 as per IS 10262(2009).

    Now first we have to assume cement quantity, so let’s assume cement quantity=50 KG and W/C ratio=0.5

    Now let’s calculate water quantity for 50 KG cement.

    Water Quantity=0.5*50=25 liter.
