Lytag has been producing lightweight, secondary aggregate for more than 40 years, using fly ash, a by-product of coal fired power generation. By diverting waste material from landfill and reducing demand on quarried aggregate, it can reduce the embedded carbon of a construction project and improve its sustainability credentials.
Lytag managing director Gareth Moores said the new producit facility would bring immediate benefits to customers. “We are now able to provide high quality consistent material to customer and project sites more quickly and efficiently than ever before, bringing time, cost and sustainability benefits for project teams, contractors and concrete product manufacturers,” he said.
Lytag says that its material is up to 50% lighter than traditional aggregate but with similar structural strength. It has been used in concrete floor slabs in the Shard, screed at Heathrow Terminal 5 and loose bulk fill at the London 2012 Aquatics Centre.
