An alternative to Portland cement set out above is the process undertaken at [[Purfleet| Purfleet cement kiln]] which is focused on the production of High Alumina Cement (HAC) also known as calcium aluminate cement (CAC). HAC is used for applications that require a resistance to chemical attack<ref>[https://www.designingbuildings.co.uk/wiki/High_alumina_cement Design Buildings Wiki]</ref>, and with no evidence of the use of waste in their production, the site at Purfleet is included in WikiWaste for completeness only.

In 2018 the UK produced 7,734,000 tonnes of clinker (from a total listed clinker capacity of UK cement kilns of 10,400,000 tonnes or 74% of capacity, excluding [[Purfleet| Purfleet cement kiln]] ), leading to to the manufacture and sale of 10,076,000 million tonnes of cement (including 935,000 tonnes of imported cement) by the five main companies in the UK. Imports by others and other cementitious materials (fly ash and GGBS) bought the total UK cementitious materials to 15,188,000 tonnes in 2018<ref>[https://cement.mineralproducts.org/documents/2018-07-23_ANNUAL_Cementitious.pdf MPA Annual Cementitious 2001-2018]</ref>. | |||
