Batching, Mixing, Placing and Compaction of Concrete
Mar 18, 2017 · 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.

Concrete Batching | Types of Batching of Concrete
Manual weight batching, semi-automatic weigh batching, and fully automatic weigh batching (batching plant). Water is an essential constituent and hence using optimum water is a must. Less water would make it concretely unworkable excess water will reduce the strength of concrete. Water must measure accurately in liters.

ASTM C138 - ACI Density, Yield, and Air Content of Concrete
Weigh the container with the concrete (2) - record value to nearest tenth of a pound. Subtract the empty container weight from the full container weight (2) - (1) = weight of concrete (3) Divide the weight of concrete by the known volume (3) / (4) = density, or fresh unit weight. There are a few unique procedures listed in the ASTM C138 to
