The full lifecycle

Every stage of a study, on a single continuous record

01

Materials

Cements, SCMs, aggregates, fibres and admixtures with gravity, absorption and moisture on record.

02

Mix design

Guided ACI 211.1 or DOE procedures, or free-form binder-aware dosing.

03

Casting

Batch quantities calculated automatically, moisture-corrected at the mixer.

04

Specimens

QR-coded cubes, cylinders and prisms, traceable from mould to machine.

05

Testing

Scheduled ages, reminders and result capture with derived strengths.

06

Analysis

Statistics, graph builder, ML models and export-ready reports.

Mix Design Wizard

Design to the standard, step by faithful step

Choose ACI 211.1 or the UK DOE / BRE procedure and the wizard walks the published sequence exactly — no blending of methods. Tables and curves are digitised with linear interpolation, every step shows its formula and citation, and any value can be overridden with the override recorded.

  • Prefill specific gravity, absorption and moisture from your materials library
  • Automatic moisture and absorption correction on the trial batch
  • Live proportions summary that updates as you go
  • Save straight into the project as a real mix design with its traceability log

Interpolated straight from the published table — every value is overridable, and the override is recorded in the traceability log saved with the mix.

Per-project ML analytics

Three algorithms, trained on your study alone

Every research study gets its own isolated models. CIVLYTIX trains Random Forest, XGBoost-style gradient boosting and polynomial regression side by side on that project's own results, reports R², RMSE and MAE for each, and hands the best performer to a live what-if predictor.

Trained only on this study's own specimens — never pooled with other material systems.

Never blended

Studies with different material systems are never pooled or cross-benchmarked.

Honest metrics

Predicted-vs-actual parity plot with the ideal-fit diagonal, plus per-algorithm error.

Retrains itself

New test results roll the model to a new version automatically, with history kept.

Literature findings — generated for this study

Compressive strength · steel-fibre shotcrete

Typical reported range

45–72 MPa at 28 days for 1.0–1.5 % hooked-end steel fibre at w/b 0.42–0.50.

Dominant driver

Water–binder ratio dominates strength; fibre dosage contributes more to flexural toughness than to f_c.

Watch-out for your mix

Above ~1.8 % fibre, reported compaction losses begin to reverse the strength gain.

Rebuilt automatically whenever this project's materials or mixes change.

AI research references

Benchmarks written for your material system

Before you model anything, CIVLYTIX generates contextual literature findings for the study in front of you — built from its actual binders, fibres, admixtures, curing regimes and measured ranges. Not generic concrete trivia, and not the same card for every project.

Study-specific

Prompted from that project's own data.

Per parameter

Separate findings per measured property.

Cached & versioned

Regenerated only when inputs change.

Step one of ML

Grounds the model before you train it.

And the rest of the lab

The unglamorous work, handled

QR specimen tracking

Every specimen gets a printable coded label tied to its mix, casting session, curing regime and test age — scan it at the machine and the result lands in the right row.

Roles & research groups

Admin, supervisor and student roles with approval-gated accounts and group-level oversight.

Testing schedule automation

Test dates generated from casting day and target ages, with overdue tracking and reminders.

Casting & batch calculators

Enter specimen counts and geometry — required volume, waste allowance and per-material quantities are computed for you.

Research-grade statistics

n, mean, SD, CoV, characteristic strength, hypothesis tests, correlation matrices and a custom graph builder.

Reports & export

Project reports and CSV exports with mixes, conditions and outcomes ready to cite.

Access

Free for researchers. Partnerships for institutions.

Students and supervisors get the whole platform at no cost — that is the point of building it. Universities, laboratories and industry teams work with us directly on rollout, governance and support.
