Advantages:

Following are the advantages of pre-cast concrete:

(a) Since production takes place in a factory, quality control is excellent.

(b) As mass production takes place, it is economical.

(c) The labour needed in the manufacturing process of the pre-cast units can easily be trained.

(d) The pre-cast products might be given the desired shape and finish with accuracy.

(e) The pre-cast structures could be dismantled, when required and they can be suitably used elsewhere.

(f)  The work could be completed in a short time, when pre-cast units are adopted.

(g) While pre-cast structures are to be installed, the amount of scaffolding and formwork is considerably reduced.

(h) The moulds used for preparing the pre-cast units are of steel with exact dimensions in all directions. These moulds are more durable and they could be used several times.
