Question

What is the maximum slump of concrete allowed in removable forms?

1) 80 mm
2) 100 mm
3) 120 mm
4) 150 mm

Answer 1

The maximum slump of concrete allowed in removable forms is generally around 100 mm, depending on construction guidelines and building codes. Slump measures the consistency of the concrete and affects its workability, structural integrity, and strength.

Step-by-step explanation:

The maximum slump of concrete allowed in removable forms depends greatly on the type of construction and the specific application for which the concrete is being used. The slump measures the consistency or wetness of the concrete mix, indicating how much it will settle after it has been placed in a form. However, for standard concrete construction using removable forms, a common maximum slump allowed is typically around 100 mm.

This allows the concrete to be workable enough to fill the forms properly and consolidate without being too wet, which could lead to issues with structural integrity, excessive shrinkage, and strength. It is important to follow the specific building codes and construction guidelines that apply to your particular project, as they can provide distinct specifications for maximum allowable slump based on the concrete mix, application, and other factors.
