What is rmc

The Indian Standard Specification IS defines RMC as: "Concrete mixed in a stationary mixer in a central batching and mixing plant or in a truck-mixer and supplied in fresh condition to the purchaser either at the site or into the purchaser's vehicles".

In India, concrete has traditionally been produced on site with the primitive equipments and use of large labour force. Ready mixed concrete is an advanced technology, involving a high degree of mechanization and automation. Using ready-mixed concrete means product is delivered finished, on demand, in the specific quantity required, in the specific mix design required. For a small to medium project, the cost and time of hiring mixing equipment, labor, plus purchase and storage for the ingredients of concrete, added to environmental concerns, may simply be not worthwhile when compared to the cost of ready-mixed concrete, where the customer pays for what they use, and allows others do the work up to that point.

For a large project, outsourcing concrete production to ready-mixed concrete suppliers means delegating the quality control and testing, material logistics and supply chain issues and mix design, to specialists who are already established for those tasks, trading off against introducing another contracted external supplier who needs to make a profit, and losing the control and immediacy of on-site mixing.

Every project has specific Ready mix concrete or RMC requirements. The architect and builders will estimate the amount of Ready mix concrete needed, which is very important, otherwise there can be other expenses connected with it. An important aspect to keep in mind is that the performance of RMC can be altered with the use of admixtures. For example, you can entrain air within the mixture, lower the water requirements, add PPP fibres to boost durability or you can even super-plasticize the concrete.

This process will make it self-consolidate and self-level. This type of requirements can be fulfilled by the concrete manufacturer. Not all manufacturers work with admixtures, but they are becoming increasingly common in a variety of different industries.

Concrete India is here to provide you with state of the art Ready mix concrete or RMC solutions at the best prices on the market. The drum of the mixer revolves at high speed during charging of ingredients and then at normal speed it keeps on rotating. You can mix the concrete at any place from site, yard or in transit. Shrink Mixed Concrete — In it, an initial mixing of ingredients is already done at the plant or factory itself and then the remaining mixing is done in transit mixer.

To determine how much mixing has to be done in a transit mixer, the test should be done and it should be kept in mind how much mixing was done at the plant. Central mixed concrete — As the name suggests, the mixing of ingredients is thoroughly done at the plant itself and then it is loaded into the truck mixer, which acts as an agitator only.

These are: Quality of RMC is great as the plants follow high-quality machines, tools and consistent methods to develop it. Testing of materials and constant monitoring is followed under strict rules.

Due to defined processes and structure dust that was caused by cement has reduced as RMC uses the bulk of concrete rather than bags of cement.

Cement is saved thus helping in preserving energy and resources.
