Cast stone batch and filler loading calculator

This tool performs arithmetic on numbers you enter. It does not hold a mix design, it does not know your resin, and it will never suggest a loading. Enter the ratio you already run, the size of the part and how many you make, and it returns the quantities to order — with the waste allowance made visible instead of hidden.

Your numbers

Nothing is pre-filled and nothing is assumed. If you do not know a value, leave it blank rather than guessing.

Mass per partAs you weigh it — finished part mass, not volume.kgParts per runpartsFiller-to-resin ratio you runParts of filler per 1 part of resin, by mass. Your ratio — this tool has none of its own.: 1PigmentPercent of total batch mass, if you add pigment.%Additives / catalystPercent of total batch mass, taken from your own documented practice.%Waste allowanceYour own scrap and residue allowance. Shown separately, never hidden inside the result.%Runs per monthOptional. Adds a monthly call-off line for procurement.runs

Enter mass per part, parts per run and your filler-to-resin ratio to see quantities. The tool will not compute anything from an assumed ratio.

Use this when

You know your ratio and need to turn a production plan into a purchase quantity.
You are pricing a run and need consistent per-batch and per-month tonnage.
You changed part size or output and need the material call-off to follow.

How this works

1. Enter batch mass or part mass and the number of parts — every value is yours.
2. Enter your own filler-to-resin ratio and any pigment and additive percentages you already run.
3. Enter a waste allowance. The tool shows the result with and without it.
4. It multiplies. Nothing is inferred, assumed, defaulted or recommended.

What this page does not determine

It does not design, validate, correct or recommend a mix. Every ratio is your input.
It does not know your resin density, filler grade, moisture content or catalyst window.
It makes no strength, finish, durability or shrinkage claim of any kind.
Nothing on this page is a structural, strength, durability or code-compliance statement. Cast stone, precast and GFRC elements that carry load, span, or form part of a building envelope are engineering work and belong with a qualified engineer.
Verify on a test patch or a sacrificial part before you change anything on a production run.

Supports: The arithmetic applied to the numbers you type.
Limitation: The tool holds no mix design, no default ratio and no material database. Wrong inputs give wrong outputs.
