Steps for manufacturing of Concrete

Steps for manufacturing of concrete:

The steps of manufacturing concrete are as follows:

a.     Batching

b.    Mixing

c.     Transportation

d.    Placing

e.     Compaction

f.      Curing

g.     Finishing

   a.      Batching: The process of measuring different concrete material such as cement, aggregate, sand, water for making concrete is known as batching. It can be done in two way

·       Volume batching

·       Weight batching

Ø In volume batching, the measurement of concrete material are taken in volume.

Ø In weight batching measurement of concrete material are taken in weight.

   b.     Mixing: in the process, all the material are thoroughly mixed in required proportion until it shows uniform colour and consistency. The mixing is done by two method.

·       Hand mixing

·       Machine mixing

   c.      Transportation: when the mixing is done the freshly mixed concrete is then transported to the construction site, this process is called as transportation. It can be done manually or mechanically.

   d.     Placing: After the transportation, the concrete are placed correctly on the formworks.

   e.      Compacting: Compaction is the process in which the air bubbles are eliminated from the freshly placed concrete. It can be done

·       Hand compaction

·       Machine compaction

   f.       Curing: Curing is the process in which concrete is kept in moisture for certain period of time. Curing should be done properly to increase strength of concrete.

   g.      Finishing: finishing is the last operation in making concrete.
