The first cement manufacturing functions near Swanscombe were opened at Northfleet by James Parker, around 1792, making "Roman concrete" from concrete rock brought from the Isle of Sheppey. James Frost opened up a works at Swanscombe in 1825, utilizing chalk from Galley Hill, having patented a brand-new cement called British Cement. The Swanscombe plant was consequently obtained by John Bazley White & Co, which came to be the biggest part of Blue Circle Industries when it created in 1900. It ultimately closed down in 1990. In between 1840 and 1930 it was the largest cement plant in Britain.
