The first products of concrete are cement, fine aggregates (sand), coarse aggregates and water. Numerous times admixtures are Employed in concrete to reinforce its Qualities. Hence, Attributes of those components and their material affect the workability of concrete.

Opus caementicium exposed in a very attribute Roman arch. In contrast to present day concrete constructions, the concrete Utilized in Roman buildings was usually lined with brick or stone.
As a consequence of cement's exothermic chemical response while setting up, big concrete structures for example dams, navigation locks, big mat foundations, and huge breakwaters generate extreme warmth during hydration and related enlargement. To mitigate these results post-cooling[sixty seven] is commonly used during construction.
