A Detailed Guide on Grading of Aggregates.

In this way, the resulting concrete mass is a void-less or dense mass. The binding property of cement is made use of to give this dense mass a cohesive stone-like character. Concrete is, an artificial stone, in a broad sense. Grading of aggregates is aimed at determining the mean size of the particle in a given batch of aggregates.

Therefore, in comparing the bleeding of CS concrete with natural sand concrete, it is important to keep the aggregate grading, particularly the fines content, similar in both mixes. Additionally, the use of an air entrainment agent is known to reduce bleeding of concrete, thus its dosage should also be kept the same between the two mixes.
