Ready Mix Concrete (RMC) - Introduction, procedure, advantages and disadvantages
Now a days, the use of Ready Mix Concrete (RMC) in large construction work has been continuously increasing. RMC is a concrete that is scientifically manufactured in batching plant and transported to the site by transit mixer without affecting its fresh properties. The transit mixer is of two types - In one type, dry concrete is made at the batching plant, loaded into agitator truck mixer and water is added during transportation. Thus wet concrete is formed. In the other type, mixed wet concrete is made at the batching plant discharged into the agitator truck mixers and transported to the site. The drum in concrete is made to rotate till the concrete is placed to keep the concrete in plastic state. Procedure The raw materials are tested in the plant before its use to ensure compliance with relevant standards. This eliminates the possibility of quality problems in the end product. The aggregates of different sizes are stored in separate bins and mixed in desired proportions to ge
