To determine the total absolute volume of all ingredients in concrete mixing, it's essential to consider the weight of all materials, including air. This consideration is important because air content affects the actual volume of the concrete mix, particularly in ensuring the desired workability and strength of the final product.

When calculating absolute volume, it’s crucial to account for how the ingredients (including aggregates, cement, water, and air) displace space in the mix. The air in the mix can significantly influence the overall volume and density of the concrete, particularly in lightweight concrete applications or when using specific admixtures that introduce air.

The other options do not fully account for this necessary aspect. Simply using the weight of materials or the volume of materials alone would not render an accurate assessment of the total absolute volume, as they neglect the influence of air content on the overall mix. Moreover, total yield weight does not directly provide the volume measure required for calculating the mixture correctly.
