Construction of the Olympic Athletes’ Village, London

In order to supply low-carbon concrete for the construction, different tests and trials have been carried out including substituting raw materials with increasing amounts of secondary or recycled materials. For example, Pulverised Fuel Ash (a by-product of producing electricity in coal-fired power stations), Ground Granulated Blast Furnace Slag (a material processed from the waste associated with steel manufacture), stent (a waste product of the Cornish China Clay industry) and recycled glass have been used.
