Cement Day
October 21 · Level 2 · #1815 of 2238
Cement Day is an informal occasion to notice a material that helps make modern construction possible. Linked to the history of Portland cement, it also recognises the people whose work supplies an essential ingredient for buildings, bridges and roads.
How it is celebrated: there is no single established set of customs. Industry features explore cement production, its inventors and its uses, while professional greetings recognise cement workers and others in construction.
Portland cement was not named after the place where it was invented. Joseph Aspdin, who patented his material in 1824, chose the name because the hardened product resembled limestone from England's Isle of Portland.
