Roll No: 17014
Batch 2017-19

2. INTRODUCTI
ON
•Ready-mix concrete (RMC) is a ready-to-use material, with
predetermined mixture of Cement, sand,aggregates and water.
•The Idea of Ready Mix Concrete (RMC) was first introduced by Architect
Jurgen Heinrich Magens, he got this patent of RMC in Germany in 1903.
•In 1907, he discovered that the available time for transportation could
be prolonged not only by cooling fresh concrete but also by vibrating it
during transportation.

3. •The first concrete mixed off site and delivered to a construction site was
effectively done in Baltimore, United States in 1913, just before the First
World War.
•The first concept of transit mixer was also born in 1926 in the United
States. In 1939, the first RMC plant was installed in United Kingdom and
in 1933.
•Between the years 1950 and 1980 considerable growth of RMC took
place in the United States.
•In India RMC was first initially was used in 1950 during the
construction sites of Dams like Bhakra Nangal, Koyna.

5. OBJECTIVE
Better quality concrete isproduced.
• Elimination of storage space for basic material at site.
• Elimination of Procurement/ hiring of plant and machinery.
• Wastage of basic materials isavoided.
Objective Of The Study
• To understand the potential of Ready Mix Concrete in IHB sector.
• To understand the demand of Ready Mix Concrete in the market.
• To identify the interested cement dealer’s those who needs RMC.
• Approaching the cement dealer’s as well as building contractors to work with RMC.
• To give the detailed information about the RMC supply process to the customer.

7. MATERIALS REQUIRED FOR
RMC
1. AGGREGATE :
Aggregates are the important constituents in
concrete.They give body to the concrete,
reduce shrinkage and effect economy.The mere
fact that the aggregates occupy 70-80 per cent
of the volume of concrete.

8. Aggregat
es

9. Aggregates are divided into two categories from
the consideration of size
• Coarse aggregate
• Fine aggregate
The size of the aggregate bigger than
4.75 mm is considered as coarse aggregate
and aggregate whose size is 4.75 mm and less
is considered as fine aggregate.

10. 2. CEMENT :
Cement is a binder material which
sets and hardens independently, and can bind
other materials together.
Cement is made up of four main
compounds,
• dicalcium Silicate (2CaO SiO2),
• tricalcium silicate (3CaO SiO2),
• tricalcium acuminate (3CaOAl2O3),
tetra-calcium aluminoferrite (4CaO Al2O3 Fe2O3).
these compounds are designated as C2S,C3S,
C3A, and C4AF.

11. where C stands for calcium oxide (lime),
S for silica and A for alumina,and F for
iron oxide.Small amounts of uncombined lime and
magnesia also are present, along with alkalis
and minor amounts of other elements.

12. 3. ADMIXTURE:
•Air-entraining admixtures (mainly used
in concrete exposed to freezing)
•Water-reducing admixtures, plasticizers
(reduce the dosage of water while maintaining
the workability)
•Retarding admixtures (mainly used in hot
weather to retard the reaction of hydration)
• Accelerating admixtures (mainly used in
coldweather to accelerate the reaction of

13. •Super plasticizer or high range water-
reducer (significantly reduce the dosage of
water while
maintaining the workability)
•Miscellaneous admixtures such as corrosion
inhibiting, shrinkage reducing, coloring,
pumping etc.

14. FLY ASH:
Fly ash is a by-product from coal-
fired electricity generating power
plants.
The fly ash is generally used in the
concrete in the following ways.
• A s partial replace for cement.
• A s partial replacement for sand.
• A s simultaneous replacement for
bothcement and sand.

15. FLY
ASH

16. WATER :
The pH value of water should be
in between 6.0 and 8.0
according to IS 456-2000.

17. EQUIPMENTS
REQUIRED:
• Storage materials- Silos,containers,Bins
• Measuring and recording equipment
• Mixing equipment
• Control systems
• Electrical, hydraulic and pneumatic drives
• Conveying systems (belt conveyors)

21. TRANSIT MIXED (OR "TRUCK- MIXED")
CONCRETE:-
While ready mixed concrete can be delivered to the
point of placement the overwhelming majority of it is
brought to the construction site in truck-mounted,
rotating drum mixers.
Truck mixers have a revolving drum with the axis
inclined to the horizontal.
Inside the shell of the mixer drum are a pair of
blades or fins that wrap in a helical (spiral)
configuration from the head to the opening of the
drum.
The concrete is loaded and mixed, it is normally
hauled to the job site with the drum turning at a
speed of less than 2 rpm.

23. NEEDS TO BE SPECIFIED BY
CONSUMERFOR RMC
•Characteristic strength or grade (N/mm2)
• Target workability or slump in mm required
• Exposure conditions for durability
requirements
Maximum water to cement ratio
Minimum cement content
Maximum aggregate size
Type of cement
Mineral admixture and its proportion (Kg/m3)

24. CHECKS BY CONSUMER
BEFOREORDERING THE RMC
• Calibrations of all measuring devices and their
accuracy.
• Mode of operation of plant shouldpreferably
be fully automatic and not manual.
•Quality of materials proposed to be used.
•Adequacy of quantity of materials used.

25. Merits of Ready-Mix Concrete
 ·A centralized concrete batching plant can serve a wide
area. Site Mix trucks can serve a larger area including
remote locations that standard trucks cannot.
 · The plants are located in areas zoned for industrial use,
and yet the delivery trucks can service residential districts or
inner cities.
 · Better quality concrete is produced. Site Mix can produce
higher compression strength with less water than standard
batching methods.
 · Elimination of storage space for basic materials at site.
Standard Batch plant need more room for their operation
than Site Mix trucks.

26. Merits
Continued Elimination of procurement / hiring of plant and machinery
 · Wastage of basic materials is avoided. With a Site Mix truck,
there isless waste and washout. This is better for the
environment.
 Labor associated with production of concrete is eliminated. It
takes more people to operate a standard batch plant than a
Mobile Mix truck.
 · Time required is greatly reduced..

27. Demerits of
RMC
·Generation of additional road traffic; furthermore, access roads,
and site access has to be able to carry the weight of the truck and
load. Concrete is approx. 2.5tonne per m³.
·This problem can be overcome by utilizing so-called 'minimix'
companies, using smaller 4m³ capacity mixers able to access more
restricted sites.
·Concrete's limited time span between mixing and going-off
means that ready-mix should be placed within 10 minutes of
batching at the plant.
·Modern additives modify precisely that time span however, the
amount of additive added to the mix is very important.
 The materials are batched at a central plant, and the mixing begins
at that plant, so the travelling time from the plant to the site is
critical over longer distances. Some sites are just too far away,
though this is usually a commercial rather than technical issue.

39. Snapshots of some dealers meet

marketing head

41. Suggestions
• Dealers are not showing interest in RMC as company is not providing small
quantity of RMC. So small TM required to supply RMC in that sector.
Transportation is a huge problem as 6 CuM TM is not suitable to supply in
narrow places.
• Dealer’s incentive is too low. So many dealers are not interested to work
with this incentive amount.
• Regular visit of company representative to the dealer’s is very important as
they are still not aware of RMC process.
• Company should organize a meeting with the dealer’s as well as
contractor’s to make them aware about RMC .
• Cost difference is huge in respect of site mixing as a result dealer’s are not
showing any interest to supply the RMC.
• More batching plant is needed in rural area also to supply in those area.

42. CONClUSIO
N:
• The concrete quality produced in ACC RMC plant is highly consistent with low
deviation order.
• It provides a high degree of overall strength of hardened concrete and the
performance of the structure at a later date.
• RMC operations are highly mechanized and fully controlled through electronic
controls and hence reduce the probability of errors in various operations.
• It is also environmentally friendly and brings down pollution due to dust at
construction can also be accelerated with the use of the RMC.
• RMC has gained acceptance in Indian industry due to several advantages
including quality control and overall economy.
