'''Concrete''' is a material commonly used in construction. It is composed of cement, aggregate, water and special chemicals known as admixtures.
==Admixtures==
Admixtures change the properties of the concrete. Different admixtures are used depending on the requirements:
*Accelerators make the concrete harden faster.
*Pigments change the colour of the concrete.
*Bonding agents create a good bond when adding new concrete to old.
