What is RMC?
RMC is a product that is manufactured at centrally located Batching plant according to a set engineered mix design. Ready mix concrete-RMC is normally delivered in two methods.
Prepared RMC it is delivered to the construction location in two different ways. The first way is using in-transit mixers which deliver the concrete mixture in a plastic state to the location. The second way is by using volumetric concrete mixer which delivers the material in the dry state and mixes it on the site.
Ready-mix concrete, or RMC as it is also known, refers to concrete that is specifically manufactured for customers to their construction projects, and supplied to the customer on site as a single product. It is a mixture of cement, water and aggregates: sand, gravel, or crushed stone.
Advantages of Ready Mixed Concrete
- Concrete is produced under controlled conditions using Consistent quality of raw material.
- Speed of construction can be very fast in case RMC is used.
- Since ready mixed concrete (RMC) uses bulk cement instead of bagged cement, dust pollution will be reduced and cement will be saved.
- With better durability of the structure, their overall service life increase and there is a saving in life-cycle cost.
- Amount of human involvement is reduced in RMC manufacturing process
- Testing of materials and constant monitoring is followed under strict rules.
- No need for space for storing the materials like coarse and fine aggregate, cement, water, and admixtures.
- Reduced noise and air pollution
Manufacturing process of RMC
Control Room:
The 'brain' of the plant that calculates and sends out the exact measurements required to each sub station, allowing them to create the specified mix.
Aggregate Bins:
This is where all the different types of aggregates are stored. Here, the exact amount of the required materials are weighed out, then carried via a conveyor belt to the mixing station ready to be mixed together.
Cement Silos :
Where the cement is stored, weighed out and transferred to the mixing station ready to be mixed along with the aggregates.
Water & Additives :
Once water is added to the dry ingredients, the wet concrete mix itself starts to form. Additives are also added for extra strength, faster curing or better workability.
Mixing Station :
Here, all the dry ingredients are mixed together with the water until the correct consistency is formed.
Mixing Station :
The mixture is discharged and loaded into the back of the drum mixer, which rotates to keep the consistency correct whilst it is transported to the job.
