Rapidmix in Action on a Variety of Environmental Projects.

The Rapidmix 400/600CW continuous mixer is known for producing quality roller compacted concrete and also meets diverse needs in environmental mixing applications. Introduction The Rapidmix 400/600CW is a fully mobile continuous mixing plant designed to handle a variety of materials with precision and efficiency. Its flexibility makes it suitable not only for civil engineering works but also for environmental uses like soil stabilization and contaminated land treatment. The Problem Many projects require semi dry or specialized mixes such as Cement Treated Base (CTB), recycled asphalt paving (RAP), or bentonite-enriched soils. Producing these mixes in the right quality and quantity can be challenging, especially when using conventional static plants that may struggle with consistency and output. What Work Was Carried Out Rapid International’s updated plant includes automated weighing for aggregates, cement, and water, ensuring accurate and detailed record keeping. The unit runs on its own power, featuring an onboard compressor and generator, and uses hydraulics to quickly shift from transport to operational status. The mixer can produce up to 400 or 600 tonnes per hour, depending on the model, with adjustable feed rates for each material. One example comes from JFK Airport in New York, where the Rapidmix 400 was employed during runway rehabilitation. The process involved milling and screening old asphalt then mixing it with cement and water on-site in the Rapidmix. This allowed the reuse of a large percentage of reclaimed asphalt paving, reducing costs and environmental impact. Another case took place in Florida, where a contractor used Rapidmix to produce high-quality cement treated base for road and pavement projects. By mixing recycled concrete with aggregates and cement, they created a durable, frost-resistant foundation that strengthens over time. The Results Using the Rapidmix 400/600CW provided both projects with a reliable, efficient way to produce consistent mixes tailored to their specific needs. The ability to work directly on-site with continuous mixing increased productivity while supporting sustainability by incorporating recycled materials where possible. Closing Note The Rapidmix continuous mixing plant offers an adaptable, effective solution for a range of civil and environmental applications. Its design focuses on quality, speed, and precise control to meet the demands of modern construction and environmental challenges.
Rapidmix Mobile Continuous Concrete Mixing Plant Enables Reuse of Waste Fines for Gallagher Group.

Gallagher Group uses Rapid International’s mobile Rapidmix 400CW plant to produce hydraulically bound materials and roller compacted concrete efficiently on site. Introduction Gallagher Group, a well-established Kent-based construction and civil engineering company, added a Rapidmix 400CW mobile continuous mixing plant from Rapid International to their operations. The plant primarily supports their Hermitage Quarry site but can also be moved to other locations as needed. The Problem Producing semi-dry mixes like hydraulically bound materials (HBM) and roller compacted concrete (RCC) with traditional static batch plants is often expensive and inefficient. Gallagher Group needed a way to use waste fines from their crushing process and produce these specialized materials on demand with better efficiency, while reducing transport and landfill costs. What Work Was Carried Out Rapid International supplied the Rapidmix 400CW, a mobile continuous mixing plant designed specifically for semi-dry concrete mixes. It features a high-speed twin shaft mixer with chill cast steel paddles that produce a consistent, high-quality mix at up to 600 tonnes per hour. The plant is self-contained with its own power source and can be set up quickly on site with a hydraulic self-erecting system. The updated model includes automated weighing for aggregates, cement, and water, helping with precise batch control and record keeping. The Results Gallagher Group has been able to recycle waste fines that were previously discarded, cutting down on haulage and landfill use. The plant reliably produces their Gallapave range of HBM and RCC products, which are used as road sub-bases and durable pavement surfaces suitable for heavy loads like airport runways and port pavements. The mobility and flexibility of the Rapidmix 400CW have allowed Gallagher to meet project demands efficiently while controlling costs. Closing Note The partnership between Gallagher Group and Rapid International has brought increased productivity and sustainability to Gallagher’s operations through modern, mobile mixing technology that addresses the specific needs of semi-dry concrete production.
Recycled Concrete – What are the Benefits?

Recycling concrete reduces waste and costs by turning old material into strong, reusable aggregate, and on-site solutions like the Rapid Reclaimer make the process efficient and affordable. Introduction Using recycled concrete has become a practical way for construction projects to cut material waste and lower expenses. Instead of discarding old concrete, which can be costly and time-consuming, recycling offers a sustainable alternative that benefits both the environment and budgets. The Problem Demolished or leftover concrete often appears unusable due to its rough condition, leading many to throw it away. But disposing of concrete involves significant costs for transport and landfill fees, alongside increased project delays. What Work Was Carried Out Recycled concrete is created by crushing and processing old concrete into high-quality aggregates that meet construction standards. These recycled materials can be used in various applications, including road foundations, parking lots, and driveways. Recycling can be done off-site at quarry facilities or more efficiently on-site using mobile equipment like the Rapid Reclaimer. This unit recovers sand, aggregate, and grey water from unused concrete, processing significant volumes while eliminating the need to transport materials elsewhere. Its design includes fixed water jets, an aggregate conveyor, and water recycling systems, making it well-suited for on-site reuse. The Results By recycling concrete on-site, projects reduce reliance on newly quarried materials, cut landfill waste, and decrease transport costs and environmental impact. The lighter weight of recycled concrete also means materials can be moved more efficiently. For businesses, these savings translate into smoother operations and better compliance with environmental regulations. Closing Note Recycling concrete with equipment like the Rapid Reclaimer makes it easier to adopt sustainable practices without sacrificing productivity or increasing costs.
