The process of measuring ingredients or materials to prepare concrete mix is known as batching of concrete. Batching can be done by two methods, volume batching and weight batching. Batching should be done properly to get quality concrete mix. Methods of Batching Concrete 1. Volume Batching In volume batching, materials are measured on the basis of volume. It […]
