For almost fifty years a huge network of RMC suppliers has served these countries. In India this industry is showing clear signs of development in last few years and has opened an enormous potential of growth of concrete manufacturing plants all over the country. Ready-Mixed Concrete (popularly known as RMC) industry in India has already established its superiority in the early years of its operation in major cities. It can be anticipated that it will grow rapidly now all over the country in other major cities as well. In this scenario lot of changes in the present construction situation can be expected. It will involve change in approach towards various material-manufacturing processes and construction techniques. This paper tries to cover how exactly RMC will act as a technological package for changes in construction industry.
To address the various specialised needs arising out of such phenomenon it is essential that some sort of knowledge and experience is made available in the various related areas which make difference in the activity of setting up and operating an RMC plant. Use of emerging technologies and information management tools available in the country can be easily made to make the relevant information available.

Civil Engineering community’s responsibility towards society concerns safe and enduring infrastructure at minimized life-cycle cost without severely affecting environment. Achievement of overall economy in terms of life cycle cost of structure and sustainability of construction by adopting environment-friendly techniques is the only alternative suitable for modern construction. To achieve this traditional methods of construction will not be sufficient and new technologies especially Ready-Mixed concrete (RMC) will need to be adopted.

To achieve this traditional methods of construction will not be sufficient and new technologies like Ready-Mixed concrete (RMC), Bulk Cement etc. need to be adopted. RMC is an appropriate technology for growing, futuristic metropolitan cities like Mumbai where growth and general public comfort have to go hand in hand. The awareness level of population is high, so an option that conserves environment, improves quality, increases cost-effectiveness and speed and eliminates nuisance can serve as the most suitable alternative. This is precisely the same RMC has to offer to the industry and the society. Use of RMC will lead to :
 Conservation Of Energy And Resources
 Minimisation Of Environmental Pollution
 Advancement Of Technology
 Assurance Of Quality Construction Projects and durable structures
 Reduction in immigrant workers
 Other social, practical and general benefits (speed, service etc.)

In India the last decade has seen emergence of Ready-Mixed concrete (RMC) in leading cities. There has been a general increase in awareness of civil engineers regarding superiority of using modern technology in construction projects. There has been an increase in trend toward specifying RMC in big projects including concrete roads. Prevailing circumstances have led to the use of RMC at various roadwork sites especially in cities like Mumbai. This technical paper aims at presenting a practical outlook towards intricacies involved and observations made at such sites.
The data referred to, in this write-up comes from concrete of M35 grade supplied by UNITECH PREFAB LTD, to some contractors of Municipal Corporation of Greater Mumbai (MCGM) for their CC-roads at different locations across Mumbai during the period September'97 to June'03.

Also, in India last few years have seen appearance of various good Ready-Mixed concrete plants in prime cities. Such prevailing circumstances have led to use of RMC at various roadwork sites especially in cities like Mumbai. This technical paper aims at presenting a practical outlook towards intricacies involved and observations made at such sites.

Civil Engineering community's responsibility towards society concerns safe and enduring infrastructure at minimized life-cycle cost without severely affecting environment. Achievement of overall economy in terms reduced recurring maintenance of structures and sustainability of construction by adopting environment-friendly techniques is the only alternative suitable for modern construction. To achieve this traditional methods of construction will not be sufficient and new technologies especially Ready-Mixed concrete (RMC) will need to be adopted. Ready-Mixed concrete is concrete manufactured at a central location in highly sophisticated and rigorously controlled plants. In conventional site mix, concreting is done at the mercy of gangs, who manipulate the cement, water and other ingredients of concrete. On the contrary concrete is an engineering material and use of proper design and technical approach can improve performance and optimize the costs. In ready mixed concrete, design as well as the proportions are accurately controlled leading to overall better quality of concrete structures. Durability of structure is improved due to high level of quality control, thereby leading to reduction in lifecycle cost and maintenance free structures. This kind of increase can have a major impact on national economy and optimised utilisation of resources like limestone, energy and industrial by-products. Also, it is an environment friendly technology as it substantially reduces air pollution arising at sites because of handling of cement, aggregates etc. at sites. In view of the above advantages, the rest of the world has adopted RMC as the appropriate technology for construction. There is a need in India as well to consciously promote this industry so as to benefit the development of public and private infrastructure in sustainable manner. In order to achieve speedy, sustainable and economical construction, we as a country should look forward to reviewing our strategies and learn from available experiences abroad to promote RMC and allied industries like bulk cement etc.

Many prestigious and critical structures have been built using either Portland Pozzolana Cement or by blending flyash directly in Concrete. The names of the famous Petronas Towers and Euro-Tunnel can be definitely quoted in this regard. However, the Indian Construction Industry has offered some resistance in using PPC or flyash in Structural Concrete. With advent of Ready-Mixed Concrete in India the doubts regarding controls in using this material are slowly being removed and engineers have become more open to the idea of using flyash as pozzolan for partial replacement of Cement in Concrete. As a result we, at our RMC plants, have been able to produce more than 2,00,000 Cubic meters of concrete using flyash. This paper intends to discuss the issues handled by us in this process. These include selection of source, collection method, monitoring of quality, mix design, production control etc.
