Mixing concrete by hand. Generally in the UK, we hand mix concrete 'on the deck', either using a slab of existing concrete (which can be hosed off and cleaned down afterwards) or on a large mixing board.

Batching of concrete is generally the proportioning of the different constituents of concrete before mixing which could be by weight or volume. Mix-design justified by trial test is the best method to achieve a concrete of desired properties.

## Mixing and Transporting Concrete

Batching is the "process of weighing or volumetrically measuring and introducing into the mixer the ingredients for a batch of concrete" (Kosmatka, 94).
