The document discusses ready mixed concrete (RMC), detailing its merits, such as consistent quality and reduced construction time, as well as demerits like high initial investment and transportation challenges. RMC is particularly beneficial for large projects in congested areas, providing better durability and lower environmental impact. It emphasizes the advantages of RMC over traditional site-mixed concrete in terms of efficiency, cost-effectiveness, and quality control.

11. MERITS OF R.M.C.
1. Better quality concrete is produced.
2. Elimination of storage space for basic materials at site.
3. Elimination of Hiring plant and machinery
4. Wastage of basic materials is avoided.
5. Labour associated with production of concrete is eliminated.
6. Time required is greatly reduced
7. Noise and dust pollution at site is reduced.
8 .No wastage at site
9. Environment friendly

12. DEMERITS OF R.M.C.
1. Need huge initial investment.
2. Not affordable for small projects (small quantity of concrete)
3. Needs effective transportation system from R.M.C to site.
4. Traffic jam or failure of vehicle creates problem if proper dose
of admixture is not given.
5. Labours should be ready on site to cast the concrete in
position to vibrate it and compact it.
6. Concrete's limited time span between mixing and going-off
means that ready-mix should be placed within 90 minutes of
batching at the plant. 45

13. SCOPE OF READY MIX CONCRETE
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. Huge industrial and residential projects.

Ready Mix Concrete Site Mix Concrete
1 Consistent Quality- concrete is made in high tech batching plants in
a computerized environment.
Quality is inconsistent–because concrete is hand mixed.
2 Construction in double quick time. Manual mixing is time consuming. Projects take longer time to finish.
3 Raw materials are chosen after strict quality checks Quality of raw materials is manually checked. Or not checked at all.
4 Large quantities of concrete can be ordered. This allows you to
upgrade yourself and handle projects of any size.
Takes more time. Repeated mixing needs to be done for large
quantities as the mixer will be too small to handle the requirement.
5 No wastage of raw materials at your site. Everything is pre-mixed at
our plants, based on your needs.
High wastage of raw materials due to manual mixing.
6 No hassle of managing labour on site. We supply ready-to-use
concrete. Our well-equipped technical crew will handle the pouring
and patching of concrete at the site.
Involves the use of labourers for mixing the concrete on site.
Management of labour means more time, efforts and money.
7 Safe work practices – no disruption in your schedule. Highly unsafe. Unskilled and untrained labourers may work
carelessly resulting in dangerous working conditions.
8 You don’t have to stock materials and watch over them. There’s no
worry about pilferage.
Risk of pilferage of raw materials is high.

17. 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.
 The Supervisory and labour costs associated with the production of RMC is less, and
the quality of concrete is high.
 It is suitable for huge industrial and residential projects where time plays a vital role.
 So ultimately it provides economy in the construction and better finish to the structure.
 Hence now a days the advantages of RMC are realized by engineers and contractors in
the construction industry.
