Ready-mixed Concrete (RMC)


Ready-mixed concrete or RMC is a type of concrete which is manufactured in a batching plant or a factory, based on standardized mix designs, and then delivered to the construction site by truck-mounted transit mixers.

The first Ready-mixed concrete plant started operating in Pune in 1987.

Most of the Ready-mixed concrete plants are located in seven large cities of India, and they contribute to about 30–60 per cent of total concrete used in these cities.

Even today, a sustainable proportion of concrete produced in India is volumetrically batched and site mixed, involving a large number of unskilled labourers.

The fraction of Ready-mixed concrete to total concrete being used is 28.5 per cent. Ready-mixed concrete is being used for bridges, flyovers, and large commercial and residential buildings.

The Ready-mixed concrete plant should be equipped with up-to-date equipment such as transit mixer, concrete pump and concrete batching plant.

Advantage of Ready-mixed concrete:

This type of concrete results in more precise mixtures, with strict quality control, which is difficult to follow on construction sites.


Disadvantages of Ready-mixed concrete:

Since the materials are batched and mixed at a central plant, travelling time from the plant to the site is critical over longer distances.
It is better to have the ready mix placed within 90 minutes of batching at the plant.
