Question: 1 / 400

The volumetric method for determining air content in concrete can be utilized with what types of aggregate?

Only fine aggregates

Only coarse aggregates

All types of aggregate

The volumetric method for determining air content in concrete is suitable for all types of aggregates, including fine and coarse aggregates. This method involves measuring the volume of air within the concrete mix by using a container filled with the concrete, followed by adding the water to fill any air voids.

When using this method, the specific characteristics of the aggregates do not impede the measurement process, as it captures the total air content regardless of whether the mix is predominantly composed of fine aggregates, coarse aggregates, or a combination of both. It is this versatility in application across various aggregate types that makes the volumetric method an effective option for assessing air content in diverse concrete mixes.
