A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource.
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of portland cement are available. The most common, called ordinary portland cement (OPC), is grey, but white portland cement is also available. Its name is derived from its resemblance to portland stone which was quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824. His son William Aspdin is regarded as the inventor of "modern" portland cement due to his developments in the 1840s. The term portland in this context refers to a material or process, not a proper noun like a place or a person, and should not be capitalized.

Annery kiln is a former limekiln of the estate of Annery, in the parish of Monkleigh, North Devon. It is situated on the left bank of the River Torridge near Half-Penny Bridge, built in 1835, which connects the parishes of Monkleigh and Weare Giffard. Running by it today is A386 road from Bideford to Great Torrington. Weare Giffard is the start of the tidal section of the River Torridge, and thus the kiln was sited here to import by river raw materials for the kiln, the product of which was lime fertiliser for use on inland agricultural fields. The old lime kiln is thus situated between the River Torridge and the now filled-in Rolle Canal built circa 1827 and railway that ran formerly from Bideford to Torrington, opened in 1872 and closed in 1966. The old trackbed now forms a stretch of the Tarka Trail.
