Ready Mix Concrete

Ready Mixed Concrete (RMC) is the concrete which is delivered in a ready-to-use manner as a single product and is specifically batched using carefully engineered design mix to achieve the desired strength with the least amount of raw materials.

RMC is defined by Indian Standard Specification IS 4926 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 use of primitive equipments, extensive labour force, large areas for material dumping, inaccurate mixing ratio, unchecked use of water - all resulting in reduced strength and quality.

RMC is an advanced technology, involving a high degree of mechanization and automation to provide accurate concreting solutions.

Batching Plant

A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete. A concrete plant can have a variety of parts and accessories, including: mixers, cement hoppers or silos, aggregate hoppers, batch plant controls, admixture units, water measuring tank and dust collectors.

The heart of the concrete batching plant is the mixer, and there are many types of mixers mainly: tilt/reversible Drum, pan and twin shaft mixer. The twin shaft mixer is the most advanced and latest technology in mixing.

Concrete plant use the control system panel to control the working of the entire plant. The computer aided control assists in fast and accurate measurement of input constituents or ingredients. With concrete performance so dependent on accurate water, cement and aggregate measurements, highly advanced and accurate load cells are used for weighing ingredients to the least error.

Concrete from a batching plant gives higher strength with lower amount of ingredients as compared to site mixed concrete. The consistency and homogeneity is also far superior.

Advantage of RMC

- Precision design mix concrete

- Highly consistent homogeneous concrete by advanced mixers

- Reduced time for construction

- Material wastage reduced to a minimum

- Freedom from procurement and storage of ingredients

- Improved quality of concrete by accurate weight measurement

- Ease of concreting by using pump instead of manual labour

- Outstanding environment protection performance

- Overall reduced cost of concreting

About RMC

Advantages of Twin Shaft Mixer

Twin shaft mixer is the most advanced mixer technology currently available in the industry. It can accommodate design mixes to produce normal concrete, self-compacting concrete (SCC), high strength concrete (HSC) and even ultra high strength concrete (UHSC).

Twin shaft mixer technology achieves a more homogeneous and consistent grade of concrete due to its three dimensional mixing capability. Twin-shaft mixers are equipped with mixing blades on both mixing shafts that are arranged so they follow the pattern of an interrupted spiral.

The special design and arrangement of the mixing blades in a twin shaft mixer create an intense turbulent mixing zone in the middle. The result is a more homogeneous mix in shorter mixing time increasing the workability with concrete on site.

Twin shaft mixer can achieve more than 95% homogeneity within 30 seconds of mixing. Compared to other mixers which can achieve a maximum of 70-80% this is a much higher homogeneous mix giving higher strength in the same amount of ingredients.

The discharge gates in a twin shaft mixer are in the entire bottom bed ensuring 100% discharge of material from one batch. Each batch starts fresh wihtout any residual material from the previous batch.
