Challenges Facing the Concrete Industry There are still a number of challenges facing the Concrete Industry. From a political and social viewpoint, improving the sustainability of concrete construction has to be the first challenge, not because concrete solutions are poor when compared with alternatives, but due to the volume needed for the modern economy. To get a fair comparison of alternatives, sustainability has to be at the level of the structure and include all three pillars of sustainability. Finding a system for combining the different indicators is essential if sustainability is to be assessed correctly and in a holistic and comparative way. Ready Mix Concrete enables fast, good quality and reliable construction. Wastages and pilferages at sites are eliminated. Time taken in finishing the day concreting is reduced by 40 to 70 percent. Labour is reduced at the site. Ready Mix Concrete creates an ecosystem for site handling to become more convenient, eco-friendly and efficient. The cost comparisons lead to skewed results when the material cost of site concrete is directly compared with the delivered price of Ready Mix Concrete. However, after incorporating the economies achieved from the material, labor and time savings as well as a reduction in failures and corrective actions, it is easy to conclude that Ready Mix Concrete provides an economically viable alternative to all construction requirements. Apart from the short-term economics, buildings and infrastructure costs are substantially reduced when a superior and durable Ready Mix Concrete is used to reduce the overall lifecycle cost of construction. It should also be appreciated that the production of concrete needs to be done reliably and sustainably. This can be done when production facilities are equipped with a certified environment, health, and safety-related controls. The use of concrete from unorganized plants without QCI or BIS certification may appear cheaper but will be detrimental to the construction industry.

1. CHALLENGES &
SOLUTION IN
RMC INDUSTRY

2. INTRODUCTION & BASIC CONCEPTS
• “Ready Mix Concrete” or RMC as it called is
mixed away from the construction sites by
mixing ingredients by weights in automatic
plants and is delivered to construction sites in
truck mounted drum mixers called “Transit
Mixers” or “Truck Mixers”.

3. • IT HAS ADVANTAGES SUCH AS HIGH QUALITY,
HIGH SPEED , ECO FRIENDLINESS, REDUCED
LIFE TIME COST AND ELIMINATION OF
PROCUREMENT AND STORAGE HASSLES.
• RMC is the e-generation’s next material for
the Indian building industry which will help
save money, time, and manpower and make
available the quality control at our door step.
• The production of ready mixed concrete has
been started in 1930’s.

4. • Since then it has gained wide spread acceptance
in many developed and developing countries. In
developed countries like U.K. and U.S.A. etc.
• the ready mixed concrete forms a major sector of
construction industry. Even the developing
countries like Thailand and Malaysia, RMC is
being used substantially. The RMC business in
India is in its Infancy.
• For example, 70% of cement produced in a
developed country like Japan is used by RMC
business there, here in India RMC business uses
around 2% of total cement production.

5. NEED FOR STUDY
• TO REVIEW THE EXITING RESEARCH work
carried out in the area of management of
ready-mix concrete industry in india.
• It is necessary to do more research in the field
of management especially in the field of
Marketing Management which will contribute
towards the growth of RMC in India.

6. LITERACHER REVIEW

7. Codes and specification
• Most of specifications related to civil
engineering construction were based on old
British standards and the construction
techniques prevalent in the developed
countries in the 50s.
• The minimum grade specified for structural
concrete is M-15 (15 N/mm²) which will be
shortly upgraded to M-20 and M-25 in case of
coastal areas

8. • In the absence of good materials, form works,
placing methods, specifications and good
construction practices, the benefits that can
be accrued by using ready mixed concrete are
being negated.
• The analytic hierarchy process (AHP) is a
structured technique for organizing and
analyzing complex decisions, can be used in
RMC which speeds up the overall process of
producing RMC

10. OBJECTIVES
• The present study is only the review of
research work conducted in the area of
management of Ready-Mixed Concrete
Industry in the context of India

11. HISTORICAL PERSPECTIVE
• Ready-mixed concrete was first patented in
Germany in 1903, but the means of transporting
it had not been developed sufficiently by then to
enable the concept to be commercially exploited.
The first commercial delivery of RMC was made
in Baltimore, USA in 1913 and the first revolving
drum type transit mixer, of a much smaller
capacity than those available today, was born in
1916. By the late 1920s and 1930s, RMC was
introduced in some of the European countries.

14. DEVELOPMENT OF RMC IN INDIA
• Ready-mixed concrete plants arrived in India in
the early 1950s, but their use was restricted to
only major construction projects such as large
dams. Bhakra and Koyna dams were some of the
early projects where RMC was used.
• In the late 1970s, the then Cement Research
Institute of India (CRI) – now the National Council
for Cement and Building Materials (NCB) – carried
out a techno-economic viability study of RMC, to
be transported without agitation.
