Ready Mix Concrete-RMC And Its Advantages And Disadvantages

Posted by

Ready Mix Concrete is a type of concrete that is mixed at any manufacturing unit. It is then transported to the site by transit mixer. Ready Mix Concrete eliminates the necessity of storing material at the site.

Ready Mix Concrete is often used at construction sites where it is not feasible or not easy to produce concrete at the site. Ready Mix Concrete usage is increasing day by day along with concrete admixtures.

Advantages of Ready Mix Concrete

  • Better quality control

    As in the case of RMC use of automatic batching machines is done, higher accuracy can be achieved for mixing.

  • No need to store material at the site

    If at the site, there is little space to store the material, RMC would be a better option.

  • Mass production is possible

    As RMC plants are specifically designed to produce concrete only, it is easy to produce in bulk, and also the speed of the construction is also improved.

  • Fewer labors are required at the site

    Labors for batching and mixing are not required.

  • As batching is done with high-precision machines, wastage of cement could be controlled.
  • Dust pollution due to cement at the site can be controlled.

Disadvantages of Ready Mix Concrete

  • Use of a set retarder and/or superplasticizer is a must

    Often the site at which RMC is used and where RMC is manufactured are far away in the distance. Hence, travel time is also increased and we need to use superplasticizers.

  • Many times RMC loses its workability before it reaches the site.
  • Traffic during transit also imparts a role in losing workability.
