QMix Auditor – Concrete Delivery Ticket Strength Verifier

Type the raw concrete batch recipe from a delivery ticket or mix submittal and instantly estimate true water-cementitious ratio, projected 7-day and 28-day strength, and site temperature risk.

Concrete delivery ticket strength verifier

Type the raw batch recipe from a delivery ticket or mix submittal. The tool estimates true water-cementitious ratio, hidden moisture water, projected 7-day and 28-day strength, and site temperature risk.

Batch ticket inputs

Use values per 1.00 m³ or 1.00 yd³. Enter cementitious materials separately if shown on the ticket.

MPa target f′c / fck
unit = m³
kg per selected yield
fly ash, slag, silica fume, etc.
kg or L per selected yield
used as a preliminary strength and timing modifier
kg per selected yield
kg per selected yield
Estimated free moisture in sand 2.0%
This shifts part of the wet sand weight into the hidden water category and reveals the true W/CM risk.
Ambient pour temperature 32°C
Affects early-age projection and hot/cold weather risk notes. It does not replace maturity meter data.
The output is a rapid engineering sanity check. Cube/cylinder results, approved submittals, trial mixes, project specifications, and local code limits remain controlling.

Need to formalize the truck acceptance check?

Use the pour log to record delivery time, temperature, slump, cube/cylinder samples, added water, rejection notes, and batch ticket references.

Mix looks plausible

Estimated 28-day strength is above the specified target and W/CM is inside a normal structural range.

True W/CM 0.47 including hidden moisture
7-day projection 25.2 MPa 3650 psi
28-day projection 36.0 MPa 5220 psi
Hidden water 14 kg from sand moisture

QA/QC verification notes

preliminary audit
Engineering limitation: QMix Auditor uses simplified empirical relationships based on W/CM, age-strength behavior, admixture assumptions, and ambient temperature. It is intended for rapid field screening only. Do not use it as proof of compliance, strength acceptance, formwork stripping approval, post-tensioning release, or mix design approval without project-specific laboratory and engineering verification.
