Question: 1 / 400

What is the specified size of the mallet required when the measuring bowl has a capacity of 14 L (0.5 ft³) or less?

0.30 ± 0.15 kg (0.66 ± 0.33 lb.)

0.60 ± 0.25 kg (1.25 ± 0.50 lb.)

The specified size of the mallet for a measuring bowl with a capacity of 14 liters (0.5 cubic feet) or less is designed to ensure that the concrete is adequately compacted during testing. A mallet of 0.60 ± 0.25 kg (1.25 ± 0.50 lb.) strikes the right balance in weight and ease of use.

This weight allows the technician to effectively compact the concrete mixture without causing damage to the measuring bowl or overstressing the material being tested. It provides sufficient force to achieve the desired density and consistency while maintaining control during the compaction process.

Using a mallet that is too heavy could lead to improper testing results either by over-compacting the mix or by causing breakage, while a mallet that is too light may not effectively compact the concrete, leading to unreliable results. Therefore, this specific weight range is critical for achieving accurate field testing outcomes.
