Creep crack

Causes:

This is due the water penetration at the edge of the railing and that steel is corroded. The corrosion is develop to the existing of that edge of that hand rail to the concrete element.

Prevention:

The proper curing is required after construction and the proper finishing also needed.

Causes:

This is one of the developing crack.

It is due to improper packing of the edge of the concrete element.

Prevention:

The requirement of quality worker and proper curing

Causes:

This hand rail is made up of precast concrete element, which affected due to environment exposure.

Prevention:

The proper curing of the precast concrete element is important

Causes:

The column structure is affected due to the rapid loading in long duration and also the water penetration to the damaged place.

Prevention:

To construct the structure as per the design of  the respected concrete element.

Causes

The lintel is affected more due to the creep of the structure and also the corrosion of reinforcement by penetration of rain water in the affected area.

Prevention:

The provision of reinforcement bar as per the design procedure.

The form work is removed in before the construction of brick work on the lintel portion.

 

Causes:

If the construction of the hand rail is not properly finishing at the corner of the rail, then the surrounding surface is damaged. The penetration of water into that damages. So the co-related adjacent surface of structure is cracked/damaged.

Prevention:

• To construct the hand rail and finishing of the edges properly.
• If the development of damages, then arrest that and also require preoper curing process.
