The Severn Trent Centre in Coventry is a 10-storey building with 3 underground storeys. It is one of the most efficient buildings in the UK, having achieved a BREEAM excellence rating and an air permeability rating of 5.

Owing to problems with the structural columns, resulting from a poor original mix design, Lafarge was called upon to take over responsibility for the supply of concrete.

The company supplied over 350m3 of Agilia Vertical concrete. Each day, 6m3 was supplied, with a 2m skip and crane used for placing. BAM specified a 60-Newton mix, which Lafarge designed to site requirements.

Continuous quality control was carried out at the plant and at the site. A complete fill was achieved, providing a high-quality surface finish with no remedial work needed.

Agilia Vertical has a mix design that incorporates a granular packing concept to ensure stability and strength. At the same time, the admixtures used give the concrete its flowing qualities.
