What are batch weights?

What are batch weights?

• A. The total weight of all materials (such as cement, aggregates, water, and admixtures) used in a specific concrete mix, calculated to ensure proper proportions for strength, durability, and workability.
• B. The weight of the cured concrete in a structure.
• C. The weight of reinforcement used in a concrete member.
• D. The weight of the formwork used during casting.

Answer: (A)

Batch weights are the total weight of all materials that go into a single concrete batch—cement, aggregates, water, and admixtures—measured so the mix proportions match the design. Weighing each component and summing them ensures the water–cement ratio, workability, and strength targets are met, and that the mixer receives the correct total amount for that batch. This quantity is recorded on the batch ticket and used for quality control. It’s different from the cured concrete’s weight in a structure, the weight of reinforcement, or the weight of formwork, which are separate measurements.
