Aggregate Blend Ratio with selected aggregate fraction in the blend of 88 tons: a worked example

This scenario runs the aggregate blend ratio calculation on the strong side: selected aggregate fraction in the blend of 88 tons, with every other input held at its documented default. a batch plant needs to verify one aggregate fraction against the total blend

The inputs for this scenario

  • Selected aggregate fraction in the blend: 88 tons (raised for this scenario; the documented default is 35)
  • Total aggregate blend weight: 100 tons (unchanged)
  • Percent conversion multiplier: 100 x (unchanged)

Working through the calculation

  • Applying the documented formula (Raw aggregate blend ratio = selected aggregate fraction in the blend รท total aggregate blend weight) to the inputs above produces each figure below.
  • At this operating point the engine returns 88 % blend share for aggregate blend ratio, the number this scenario is built around.
  • At this operating point the engine returns 0.88 value for raw aggregate blend ratio.
  • At this operating point the engine returns 100 x for percent conversion multiplier.
  • At this operating point the engine returns 100 value for total aggregate blend weight.

How this compares with the baseline

  • Against the tool's baseline example, where selected aggregate fraction in the blend sits at 35 tons and the headline result is 35 % blend share, this scenario comes in 151% above the baseline at 88 % blend share.
  • Use it when verifying a batch against a mix design, back-calculating a fraction's share from scale tickets, or checking gradation after a material change. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Aggregate Blend Ratio: 88 % blend share (headline result)
