Aggregate Industries has invested £15 million into a manufacturing facility dedicated to the production of Lytag, a lightweight aggregate that uses Pulverised Fly Ash (PFA), a by-product of coal-fired power generation.
Set within the confines of Drax Power Station in Selby, North Yorkshire, the facility has significantly increased access to Lytag for architects and specifiers throughout the UK.
Lytag is a lightweight aggregate that is manufactured by transforming fly ash into small pellets which are heated to 1,100°C. The rounded pellets range in size to a maximum 14mm and are up to 50 percent lighter than natural aggregate.
Lytag has been used across a variety of high profile projects including The Shard, The Leadenhall Building and the ‘Walkie Talkie’ building. It is also regularly supplied as a drainage material as well as being used in specialist fill and precast applications.
According to Aggregate Industries’ general manager Steve Curley, the Lytag facility has brought down time and costs for project teams, contractors and concrete product manufacturers, as well as a host of sustainability benefits.
