Ready Mix Concrete-RMC and Its Advantages and Disadvantages

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, and higher accuracy can be achieved for mixing.
No need to store materials 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 improved. This helps in achieving speedy construction.
Fewer laborers are required at the site

Labors for the batching and mixing of concrete are not required.
As batching is done with high-precision machines, the wastage of cement can be controlled.
Dust pollution due to cement at the site can be controlled with the use of Ready Mix Concrete.

Disadvantages of Ready Mix Concrete

The use of a set retarder 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 the transit of concrete also plays a role in losing workability.
If we use transit mixers for Ready Mix Concrete then there are also chances of segregation in concrete because of continuous agitation.
