? This report continues from 09/11.
The elevated formwork for the heat duct tunnel roof is set and ready for the pour. Here we see the reinforcing steel bars bent and hooked at the ends to be embedded in the concrete.


? Mixing the concrete leaves air bubbles in the mixture.


? A vibration process is carried out to get rid of the air bubbles.


? Trowels are used to smoothen out the concrete to remove any ridges or gaps.


? The elevated slab formwork will hold the one and one-half cubic yards of freshly poured concrete for the next couple of days to cure. The concrete roof is secured to the structure’s walls, reinforcing the walls and adding durability and strength for earth to be later placed on top. The next stage will involve building a wall at the end of the roof.
We continue this report at the next stage of construction.
