The grey powder we call cement appears rather insignificant, but it is a vital part of the modern world. Cement mixed with water provides the 'glue' that binds together sand in mortar, and sand and aggregate in concrete which is an essential material used in buildings of all types as well as roads and dams.
For more than 200 years it has also been the most cost effective binder for |
underwater or moist area usage as the chemical reaction of water with cement makes it an invaluable component in harbourside buildings or skyscraper foundations.
