Industrial & Construction

Construction materials & chemical mix ratios — engineered proportions for epoxy pours, concrete batches, and field work.

Epoxy / Resin A:B Mixer

Set the manufacturer mix ratio (e.g. 2:1, 4:1, 100:35) and target batch size. Part A (resin) and Part B (hardener) are calculated to two decimal places.

For 1000 total at ratio 2:1:

Part A — Resin / Base

666.67

Part B — Hardener / Catalyst

333.33

Concrete Mix Scaler

Scale standard cement:sand:gravel volume ratios to a target batch weight. Density factors convert volume parts to kilograms or grams.

Standard presets

Custom ratio (cement : sand : gravel, by volume)

Weights use standard densities: cement 1.44, sand 1.60, gravel 1.50 kg/L per volume part.

100 kg batch at volume ratio 1:2:4:

Cement

13.53 kg

Sand

30.08 kg

Gravel

56.39 kg
