lime factsheet - ebook

Lime is a traditional and environmentally-friendly building material that was largely replaced by cement during the 20th Century, but is now coming back into fashion. Various types of lime are used in building as mortars, renders, plasters, slurries and washes. All are made from limestone, which is a sedimentary rock made from the dead bodies of sea creatures that produce calcium carbonate (coral, shellfish, some planktons). Most limestone was laid down in the Cretaceous period (60-150 million years ago).
