What do you mean by Batching of Concrete?

Proper Batching improves the workability of concrete by reducing the segregation or bleeding in concrete. It helps to get a smooth surface of the concrete. It also increases the speed of construction and minimizes the wastage of concrete ingredients. Hence, batching of concrete is an essential process while making concrete.
