1. INTRODUCTION
Ready-mix concrete (RMC) is a ready-to-use material, with predetermined mixture of
cement, sand, aggregates and water. RMC is a type of concrete manufactured in a factory
according to a set recipe or as per specifications of the customer, at a centrally located
batching plant.
It is delivered to a worksite, often in truck mixers capable of mixing the ingredients of the
concrete en route or just before delivery of the batch. This results in a precise mixture,
allowing specialty concrete mixtures to be developed and implemented on construction
sites. The second option available is to mix the concrete at the batching plant and deliver
the mixed concrete to the site in an agitator truck, which keeps the mixed concrete in
correct form.
RMC is preferred to on-site concrete mixing because of the precision of the mixture and
reduced worksite confusion. It facilitates speedy construction through programmed
delivery at site and mechanized operation with consequent economy.
It assures consistent quality through accurate computerized control of aggregates and
water as per mix designs. It minimizes cement wastage due to bulk handling and there is
no dust problem and therefore, pollution-free.
2.LITERATURE REVIEW
1. Taware Yogesh Vilasrao , et.al.,(2016) studied on ‘A Literature Review on Ready-
Mixed Concrete Industry in India’.The present paper aims to review the existing
research work in the a lant and delivered at construction site with the use of truck
mounted rea of management especially related to the Marketing Management of the
Ready-Mixed Concrete in India. Ready- Mixed Concrete is the concrete which is
manufactured at the central batching p Transit Mixers. The Ready-Mixed Concrete is the
best alternative to Site Mixed Concrete as it has may advantages over Site Mixed
Concrete.
2. Vipin V. M., et.al.,(2014) studied on‘Compressive Strength of Ready Mix Concrete
Using Soft Computing Techniques’.Compressive strength of concrete is a major and
perhaps the most important mechanical property, which is usually measured after a
standard curing of 28 days. In this research work, 28-day compressive strength of Ready
Mix Concrete has been estimated by using propagation neural network, Fuzzy Logic and
Adaptive Neuro Fuzzy Inference System (ANFIS) modeling. The data for the ready
mixed concretes (RMC) were collected from RMC batching plant. Various models has
been has been developed and the effects of each parameter on networks were studied for
Artificial Neural Network (ANN), Fuzzy Logic and ANFIS models.
3. Amiyangshu Biswas , et.al.,(2016) studied on‘Study on Ready Mix Concrete’.The
Ready Mixed Concrete in India on commercial basis started in 1994 and has achieved
about 2% conversion from the site-mixed concrete by the year 2001. It is heartening that
the acceptability of Ready mixed concrete is increasing though at a slow pace. At the
present, the cost differential between Ready-mixed concrete and site mixed concrete is
proving major constraint in its growth. This problem will be resolved with the increasing
awareness about the advantages of RMC by the end consumers.
3.LITERATURE REVIEW CONCLUSION
The research work carried out in the area of management of the Ready-Mixed Concrete is
limited in India. The literature on the quality, inventory and supply chain aspects of the
Ready-Mixed Concrete
Production of RMC in large quantities away from the actualsite of placing , It is very
useful in cities where demand of concrete is very high and construction sites are in
congested areas where mixing on site is not possible. It is suitable for pro-jects likeDam,
Roads, Bridges, etc.
The ANFIS which have the Triangular membership function could predict the 28-day
compression strength of ready mix concrete in a best manner and the minimum required
error in comparison with the fuzzy models.
The ANN models, which can easily incorporate additional model parameters, give less
scattered estimated value results than those given by the other models.
From the results obtained it can be concluded that the ANN models are more suitable
and feasible in modeling of complex problems

1. Major concerting projects like dams, roads, bridges,tunnels, canals etc.
2. For concreting in congested areas where storage of materials is not possible.
3. Sites where intensity of traffic makes problems.
4.When supervisor and labour staff is less.
5. To reduce the time required for construction etc.

6.CONCLUSION
Ready Mix Concrete is a modern technique of production of concrete in massive
quantities away from the actual site of placing.
It is very useful where demand of concrete is very high and construction sites are in
congested areas, where mixing on site is not possible due to lake of storage place.
RMC is ready to use material. It is widely adopted throughout the world.
It gives higher strength to the structure and it also provides higher Durability to the
structure.
It reduces noise pollution as well as air pollution
