WHAT
IS A CEMENT CONCRETE
Cement concrete is a mixture of cement coarse
aggregate, fine aggregate (non coherent materials) and water to form a hard
coherent mass as a result of the chemical reaction which takes place between
the water and the cement (hydration). It is a man made composite: the major
constituent of which natural aggregate such as gravel is and sand or crushed
rock. Alternatively, artificial aggregate for example: blast-furnace slag,
expanded clay, broken brick and steel shot may be used where appropriate.
