Rapid International's mobile mixing plant

A Rapid International product story

Edited by the Buildingtalk editorial team Feb 17, 2010

Rapid International manufactures a mobile continuous mixing plant which can produce Roller Compacted Concrete, and cement treated aggregate base and soil.

The Rapidmix 600 mobile continuous mixing plant has produced 6inch and 8inch Roller Compacted Concrete at the BMW assembly plant in the USA.

The project involved paving the parking lots, roads and trailer storage surrounding the new BMW assembly plant, using the Rapidmix 600, owned by The Morgan Corporation.

Along with Roller Compacted Concrete, the machine also produced cement treated aggregate base and cement treated soil.

The Rapidmix 600 mobile continuous mixing plant is manufactured by Rapid International, based in Northern Ireland.

The Rapidmix 400 and 600 are both sold via a dealer network in the US which is overseen by Rapid International USA.

The plant is completely mobile and self-contained with its own power source.

It is fitted with a self erecting system using hydraulics, which means that the plant can change from travel mode into a fully operational within a few hours.

The Rapidmix 600 mixes up to 600 tonnes per hour depending on application and feed rates are fully adjustable for the aggregate, cement and water systems.

The benefits of using the Rapidmix 600 mobile continuous mixing plant with a Roller Compacted Concrete application is that it has the mixing efficiency needed to evenly disperse the relatively small amount of water used.

Dump trucks then transport the Roller Compacted Concrete and discharge it into a paving plant, which places the material in layers up to 10 inches thick and 42 feet wide.

Compaction begins immediately after placement which is how the concrete attains its level of smoothness, density, surface texture and strength.

This stage continues until the density requirements are met.

The final stage is curing where moisture is applied, allowing hydration of the concrete, thus causing it to harden and strengthen.

The machine can work on a variety of applications such as bentonite landfill sealing, dam construction, contaminated soil stabilisation as well as roller compacted concrete and cement treated base for road construction.
