Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows. Cement:
That said, shown to the right and below are two perfect precast concrete mix designs. Mix 1 is a traditional mix that typically is used in larger products with normal weight material, while Mix 2 is an accelerated self-consolidating concrete mix that is used in smaller products with tight form spacing (2-inch-wide walls) and no reinforcing. Mix 1
l Accurate batching is a prime concern for every concrete plant to ensure the closest possible compliance with the given mix design. l AS1379 recognises that tolerance are a practical necessity and has set requirements for all concrete ingredients. l Errors in batching can alter the concrete’s expected properties. The

Factors affect concrete batch plant cost Materials Influence Costs Of A Concrete Batch Plant. Cement, sand, fine sand, gravel, fly ash, slag, admixture and all other materials costs can be relatively simple calculation according to the ratio and the unit price of raw material.
Ready mix concrete is also produced in batching plant only , the difference is that it is produced away from construction site and brought to site in transit mixers.
However, for producing ready-mix concrete, the mixer can well mix in about 15 to 30 secs. Concrete mixer having one cubic meter capacity high-speed Pan Mixer takes only about 2 minutes for batching and mixing. The RMC batching plant takes about 12 minutes to load a transit mixer of 6 m3 capacity. e) Transporting Concrete
The concrete mixer can mix up to 9m 3 . It can have tilting or non-tilting drum, open top revolving blade or paddle. Typical complete mixing times of this machine is minimum of 1 min. for up to 1 m 3 or less mixer capacity plus 15 seconds for each additional m 3 or fraction thereof.
