This is a very synonymous trade with engineering works, especially the engineering of buildings. Most with the modern construction has its structural frame fabricated out of concrete. There are two main categories of concrete:
?? Mass Concrete: This is usually a 'weak' version of concrete. This means that this doesn't perform any load showing duties. It is applied to ground floor slabs, platforms or simple bases for light works.
?? Structural (tough) concrete: This is used to carry loads and is therefore a common component of buildings and other structures like retaining walls. It is usually added strength properties by the use of steel (reinforcement). The specification of concrete will likely be dependent on the quantity of strength it is designed to carry.
