What is the maximum size for fine aggregates as per standard classification?
Recall the sieve size for fine aggregates.
Name two properties that impact workability in aggregates.
Think about how different shapes might fit together.
What is the primary effect of proper grading of aggregates in concrete?
Consider how grading relates to the compactness of the material.
