Concrete Technology is about the properties of concrete needed in construction applications, including strength and durability, and provides guidance on all aspects of concrete from mix design to batching, mixing, transporting, placing, consolidating, finishing, and curing.

There are two types of concrete mixes, i.e. nominal mix and design mix. Nominal mix is used for normal construction works such as small residential buildings. Most popular nominal mix are in the proportion of 1:2:4.
