3D Concrete Mix & Printability Evaluator
Compare 3D concrete trial mixes, calculate water/binder ratios and batch scaling, and record pumpability, extrusion, buildability and working-time checks.

3D Concrete Mix & Printability Evaluator
Document a mix. Record a trial. Compare the evidence.
Compare measured trials against your own project criteria. This tool does not predict printable-mix performance or approve structural use. Blank criteria stay incomplete.
Trial identity
Batch ingredients
Enter kg for this batch. Binder includes cement and SCMs. Water must be effective free water after moisture/absorption correction, including any admixture carrier water; avoid counting it twice. Admixture mass is as-supplied product mass.

Process & batch scaling
Scaling uses measured batch yield, not assumed density. The flow estimate assumes a solid rectangular bead; actual shape, cavities, slip and delivery losses can change demand. It is a planning calculation, not a pumping acceptance limit.
Evidence against entered criteria
Use a consistent test method across trials. For qualitative checks, describe the expected condition and record your assessment. For numeric checks, enter the measured value and the project minimum or maximum. Leave an unperformed check blank.
Compare trials
Compare only trials with compatible materials, equipment, layer timing, test methods and criteria. A green trial result is a match to entered criteria, not mix approval or wall acceptance.

Work stays in this page until you export it or explicitly save it in this browser. A local save may be unavailable in private browsing or embedded views. JSON retains editable records; CSV is a flat report.
Calculation basis & limitations
Water/binder = effective free water mass ÷ total binder mass. Aggregate/binder = entered aggregate mass ÷ binder mass. Admixture dosage = as-supplied admixture mass ÷ binder mass × 100. Target quantities = batch ingredient masses × target volume ÷ measured batch yield.
Rectangular-bead demand (L/min) = bead width (mm) × layer height (mm) × print speed (mm/s) × 60 ÷ 1,000,000. This geometric estimate does not model pressure, rheology, buildability, open time, bond strength or hardened structural performance.
Qualify the material and printing system through the approved trial and testing programme. This record does not replace laboratory reports, design checks, system qualification or the project ITP. No universal acceptance limits or strength forecasts are supplied.
