7. About concrete batching Concrete batching consists of producing concrete or concrete products by mixing cement with sand, rock, aggregate or other similar materials. In a concrete batching plant, the raw materials are mixed using a front end loader or overhead bin concrete batching techniques.
Once concrete mix design is carried out, the first task is batching of concrete materials like cement, aggregates, admixture, etc. The batching of concrete is done by measuring and combining required concrete ingredients either by weight or by volume as per the mix design.
Today, different types of concrete are categorized according to their method of installation. Ready- or pre-mixed concrete is batched and mixed at a central plant before it is delivered to a site. Because this type of concrete is sometimes transported in an agitator truck, it is also known as transit-mixed concrete.
In order to determine whether or not the concrete meets specification requirements for cement content, water-cement ratio, etc. the Inspector must know the exact amount of materials used in mixing the concrete.
