PREPARED YIELD

Mortar mix bags — mixed mortar yield per bag scenarios.

How does changing mixed mortar yield per bag affect mortar mix bags when the other inputs stay fixed?

What this decision changes

Prepared yield divides the measured demand before whole packages are rounded. Dry package mass and prepared volume must remain separate. Method basis: Enter actual installed solid masonry volume, excluding mortar and openings. For hollow units, specify the intended filled space in your own volume data; this tool does not choose grouting or reinforcement.

The focus is mixed mortar yield per bag. All other shared inputs remain fixed for each evaluated range.

Measured plan and product inputs

Mixed mortar yield per bag

L/bag

Where to get this value

Use the usable coverage or mixed yield printed on your product label for the stated application. Do not substitute bag weight for finished volume.

Waste allowance

Shortcuts only; choose your own allowance above.

Where to get this value

Enter your own allowance. Presets are input shortcuts, not a construction recommendation.

Masonry segment 1

Wall length

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Wall height

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Specified masonry depth

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Opening area

m²

Where to get this value

Measure only the area, length or quantity to deduct, in the unit shown. Keep this consistent with the surface being calculated.

L/bag

Where to get this value

Use the usable coverage or mixed yield printed on your product label for the stated application. Do not substitute bag weight for finished volume.

Upper supplied comparison value

L/bag

Where to get this value

Use the usable coverage or mixed yield printed on your product label for the stated application. Do not substitute bag weight for finished volume.

Keep the comparison within scope

Use alternative yields only when they come from the selected products and the same preparation basis.
