ETYM Old Fren. cement, ciment, French ciment, from Latin caementum a rough, unhewn stone, pieces or chips of marble, from which mortar was made, contr. from caedimentum, from caedere to cut, prob. akin to scindere to cleave, and to Eng. shed.
Any bonding agent used to unite particles in a single mass or to cause one surface to adhere to another. Portland cement is a powder obtained from burning together a mixture of lime (or chalk) and clay, and when mixed with water and sand or gravel, turns into mortar or concrete.
In geology, a chemically precipitated material such as carbonate that occupies the interstices of clastic rocks.
The term “cement” covers a variety of materials, such as fluxes and pastes, and also bituminous products obtained from tar. In 1824 English bricklayer Joseph Aspdin (1779–1855) created and patented the first Portland cement, so named because its color in the hardened state resembled that of Portland stone, a limestone used in building.
1. A building material that is a powder made of a mixture of calcined limestone and clay; used with water and sand or gravel to make concrete and mortar.
2. Any of various materials used by dentists to fill cavities in teeth.
3. Concrete; pavement is sometimes referred to as cement.
4. Something that hardens to act as adhesive material. + prikaži više

A strong hard building material composed of sand and gravel and cement and water.
Building material composed of cement, stone, sand, and water. It has been used since Egyptian and Roman times. Since the late 19th century, it has been increasingly employed as an economical alternative to materials such as brick and wood, and has been combined with steel to increase its tension capacity.
Reinforced concrete and prestressed concrete are strengthened by combining concrete with another material, such as steel rods or glass fibers. The addition of carbon fibers to concrete increases its conductivity. The electrical resistance of the concrete changes with increased stress or fracture, so this “smart concrete” can be used as an early indicator of structural damage. + prikaži više
