Formwork MCQ with answer and solution

Concept

Operations involved in formwork construction

Formula

NONE

Step-by-step solution

1. Formwork construction includes shuttering, which forms the vertical or horizontal surfaces to retain fresh concrete. 2. Propping and centering provide the temporary structural support underneath horizontal forms to carry concrete weight. 3. Provision of camber is provided in formwork to counteract expected structural deflections upon formwork removal. Answer: D

Explanation

Formwork construction requires a combination of structural support, surface moulding, and geometric adjustment operations. Propping and centering provide temporary vertical support, shuttering forms the containment walls for wet concrete, and camber accounts for expected deflections upon curing. Hence, all of these steps are essential components of formwork installation.

Why the other options are wrong

A) Propping and centering form only a part of the total formwork construction process. B) Shuttering represents only the vertical or side sheeting component of formwork operations. C) Providing camber is a design adjustment made within formwork but not the sole operation.

Shortcut

Formwork includes propping, shuttering, and camber = All of the above.

Common mistake

Restricting formwork operations to vertical shuttering alone rather than including propping, centering, and camber adjustments.
