Calculating the yield of concrete involves determining the volume produced from its constituent materials, such as cement, water, aggregates, and any admixtures. The yield is usually computed by taking into account the specific proportions of these materials used in the concrete mix and confirming that they will produce a certain volume when mixed.

This approach considers the materials' contribution to the total volume of concrete, accounting for factors like the density and specific gravity of the materials involved. It provides an accurate method for predicting the amount of concrete that will be produced, which is essential for planning and ensuring that enough material is available for the project.

Other methods mentioned, such as measuring only water content or evaluating the height of placed concrete, do not provide a comprehensive assessment of the entire mix composition. Measuring mixing time alone does not relate directly to the yield of concrete produced. Therefore, determining the yield through the constituents' volume gives the most precise and actionable information for concrete yield calculations.
