During the construction phase, the early concrete strength was low, and the formwork and steel bars were stacked on the beams and slabs too early, causing deformation and cracking due to the load.
When the concrete strength is low, removing the formwork too early can cause cracks due to the self gravity of the structure.
Therefore, during the construction process, it is not advisable to stack steel bars and formwork for loading too early.
The dismantling of concrete structures shall be strictly carried out in accordance with relevant standards to avoid severe cracks in concrete beams and slabs caused by premature dismantling, impact on young concrete, and insufficient steel reinforcement protection layer.
