Concrete Mix Design - Design Mix Concrete & Nominal Mix Concrete

Mix design can be divided into following two categories. 1. Design mix concrete and 2. Nominal mix concrete. 1. Design Mix Concrete: When the proportions of concrete ingredients are decided by adopting certain established relationships ( based on assumptions from a lot of experiments) to produce the concrete it is known as design mix concrete.

British Standard concrete mixes

This means that we produce concrete that complies with the guidelines set in the European Standard and the British Standard parts 1 and 2. Concrete that is produced to this standard is deemed not to contain harmful ingredients in quantities that could affect the durability of the concrete or potentially corrode reinforcements.
