Some vital factors for formwork failure

This is a useful tutorial for civil engineering students where they will be familiar with the main causes of formwork failures in construction site.

WHAT IS FORMWORK: It stands for a mould or open box similar to container into which the fresh concrete is poured and consolidated. As soon as the concrete is arranged, the formwork is eliminated and hard mass is formed in the shape of the inner face of the formwork.

BENEFITS OF FORMWORK:

It molds the concrete to required shape and size as well as manages its location and alignment.

It is also useful for transmitting the external temporary load.

REASON FOR FORMWORK FAILURE

a. Inaccurate & premature stripping and shore ejection
b. Insufficient bracing
c. Imperfect connections
d. Faulty design
d. Vibration
f. Inconstant soil under mudsills, shoring not plumb

g. Insufficient control of concrete placement
h. Not giving proper attention to formwork details
i. Lack of following codes and standards

SAFETY PRECAUTION:

Material that is utilized for building up the formwork should abide by the specification
Formwork should be affixed tightly and perfectly
Constructed are should be safeguarded to resist destruction of formwork.
Warning sign should be provided at the area where the formwork is set to resist the entry of people so that no damage is occurred to formwork.

The formwork should be examined properly prior to pouring of concrete.
