In India concrete is produced by
conventional methods in most of the construction sites. From the
experience it has shown many shortcomings such as:
-
Quality assurance not guaranteed.
-
Inadequate control on aggregates
for size.shape and grading.
-
Optimum Water-cement ratio not
followed.
-
Labour intensive.
-
Requires large space for storage
of aggregates and cement.
-
Time consuming operation.
-
Wastage of costly input materials.
-
Noise and dust pollution.
In order to usher in modernization
and development of the construction industry,
industrialisation of concrete is necessary.RMC is one such technology.
As per IS 4926-1976 "Ready mixed concrete is a CONCRETE
delivered at site or into the purchasers' vehicle in a plastic
condition and requiring no further treatment before being placed
in a position in which it is to be set and hardened".Ready
mixed concrete is a high quality concrete of required grade
produced under strictly controlled conditions in a Centralised
automatic batching plant and supplied to the customers in transit
mixers for placement in the structure.
All the constituents of RMC undergo stringent quality control
process carried out by qualified and experienced personnel in
the laboratories before the product is batched and sent for
placement in the structure through special pumps.

HOW DOES RMC Score Over Conventional Mixing?
|
Considering the various hidden costs associated with conventional
mixing,RMC is a better alternative to the conventional mixing
due to following factors:
-
Unique flexibility of providing tailor - made
concrete suited to different applications.
- Assured and uniform quality of required grades.
- Speedy construction through continuous mechanised operations.
- Need for ordering and storing of raw meterials for concrete
at site eliminated.
- Multi transporation of raw materials for concrete eliminated.
- Minimisation of materials wastage in view of bulk handling and
storage.
- Elimination of the need for Quality and quantity checks on raw
materials at size.
- Environmental friendly.
RMC is sutable for large construction projects like dams, bridges,
industrial structures as well as small and medium projects and will
ensure quality concrete even to small one time consumers.

COROMANDEL READY MIX CONCRETE
|
Our COROMANDEL RMC plant is set up at Thirumudivakkam near Thiruneermalai
in the suburbs of Chennai. The plant is equipped with the state-of-the-art
technology package comprising of automatic batching plant, transit
mixers, concrete pumps and fully equipped laboratory manned by the
best in the industry.
The nerve and brain of our RMC plants is the quality control lab
equipped with sophisticated instruments and manned by trained and
widely experienced personnel.The quality is monitored at every stage,
right from receipt of raw material to despatch and placing of concrete,
which ensures that consistent quality reaches the customer.
The following tests are conducted for quality assurance
- Cement: Water consistency, IST/FST, Compressive strength and
Chemical analysis.
- Fine Aggregates: Sieve analysis, Silt test, Specific gravity/Density,
Moisture absorption test and Chemical analysis.
- Coarse aggregates: Sieve analysis,Crushing value, Abrasion value,
Specific gravity/Density and Chemical analysis.
- Water: Chemical analysis.
- Concrete: Workability, Compressive Strength.
Our Technical Services cell offers you the following services:
-
Concrete testing facilities.
- Technical assistance for designing concrete mixes.
- Technical guidance for customers in construction aspects.
