Coarse Aggregate Gradation Analysis Calculator
Introduction & Importance
Coarse aggregate gradation analysis is crucial in construction to ensure the strength and durability of concrete. It determines the particle size distribution of coarse aggregates, which significantly impacts concrete’s workability, strength, and durability.
How to Use This Calculator
- Enter the sieve size in millimeters.
- Enter the percentage of aggregate passing through the sieve.
- Click ‘Calculate’.
Formula & Methodology
The calculation involves finding the cumulative percentage passing for each sieve size using the formula:
Cumulative Percentage Passing = (Sum of percentages passing for all smaller sieves) + (Percentage Passing for current sieve)
