Question

With single post shores, when is reshoring erected?

1) When the original forms are removed, if the concrete is required to support loads greater than its capacity
2) Prior to removal of original forms, if the concrete is required to support loads greater than its capacity
3) Two hours after original forms are removed, if the concrete is required to support loads greater than its capacity
4) Never; reshoring is not necessary with most original forms

Answer 1

Reshoring is erected when the original forms are removed if the concrete requires support for loads greater than its capacity to ensure proper curing and structural integrity.

Step-by-step explanation:

Reshoring is a process that involves erecting temporary supports for concrete structures after the original formwork has been removed and before the concrete has reached sufficient strength to support its own weight and additional loads. The answer to the student's question is option 1: When the original forms are removed, if the concrete is required to support loads greater than its capacity. This ensures that the partly cured concrete does not suffer from excessive stresses, which can lead to structural failures or defects. Reshores redistribute the load and allow the concrete to continue curing safely and effectively. It is critical in construction to ensure that reshoring is applied correctly to prevent compromise in the structural integrity of the concrete during the curing phase.
