A Cementech MCD10MX-150 has been supplied to fulfil trench-filling applications in North Yorkshire undertaken by the UK’s largest utility company.

The first volumetric mixer to be added to their fleet, the machine was chosen for its proven ability to handle high clay-content recycled materials, whilst offering a cost saving over foamed concrete.

The Engineering Operations Manager had previously researched the possibilities of using recycled excavated materials, and set a target of 90% reusage. One of the major concerns was the necessity to handle materials with the high clay content normally encountered – up to 25% - which can place a heavy stress on machinery. Armcon conclusively demonstrated the ability of the Cementech machines to meet this demand.

The waste from the trench excavations is crushed and screened in two grades: one equivalent to gravel, the other to sand. These graded materials are loaded into the hoppers of the Cementech mixer and mixed with cement during placement to provide the infill. Using recycled materials in this way enables the operator to match the characteristics of the ground at the trench site, without having to use foamed concrete, which is a more expensive option.

Armcon engineered and supplied a complete package, mounted on a Volvo FM12 8x4 chassis, thereby reducing the administration demands on the customer.
