Ready Mix Concrete – RMC
- What’s ready mix concrete?
- Ready-mix concrete (RMC) is a type of concrete
which manufacture in the factory as per approved mix design, which is called
Batching Plant (BP) or Concrete Batching Plant.
- Ready-mix concrete (RMC) mixing at Concrete
Batch Plant and after mixing it’s brought to the construction site by
truck mixer or transit mixer.

- Concrete Mixer
- Concrete mixers are machines that blend cement, aggregates, and water together to form the concrete paste or slurry. an honest concrete mixture should not only
uniformly mix the ingredients, but they
ought to also discharge the combination without
disturbing its uniformity. this will be judged by
the uniform consistency and color of the slurry.

- Concrete made dry at the batching plant, loaded into the agitator truck mixer and water added during transportation
- Mixed wet concrete made at batching plant,
discharged into the agitator truck mixer and transported at the site.
- The drum of the truck mixer is rotated during transportation in order to keep concrete in the plastic state.

- Advantages of Ready-Mix Concrete
- It allows speedy construction through
programmed delivery at site, mechanized operation with acceptable
economy.
- Usage of Ready Mix Concrete (RMC) reduces the
labor cost and site supervising cost.
- The Consistency in the quality of concrete is
maintain through accurate and computerized control of all material,
included cement, aggregates, water, and admixture (chemical) as per
required design mix.
- Usage of RMC also reduces the wastage of raw
materials during storage and mixing.
- Using RMC reducing the construction time.
- DISADVANTAGES OF READY MIXED CONCRETE:
- Transit time might from the time of preparation
of concrete on the distribution site, might affect the performance
- This are got to add extra water or
penetration to take care of functionality consistent
with the specification.
- On-site, quality assurance (QA) / internal
control (QC) has got to test functionality through fatigue
testing before getting used for manufacture.
- Traffic during the transit of concrete
might end in the setting of concrete therefore the addition
of entrances is required to delay the setting period.
- Formwork and placing arrangements should be
prepared during a big area beforehand as
concrete could be bought in large portions.
