ASTM C78/C78M Flexural Strength of Concrete: Workflow, Formula, and How Aldoa Simplifies Testing
ASTM C78 flexural strength test: third-point loading procedure, modulus of rupture formula, lab pitfalls, and reporting guide for concrete labs.
Construction materials testing (CMT) labs are switching to digital reporting because paper forms and spreadsheets can't keep up with the turnaround, accuracy and audit requirements clients now expect. Digital reporting captures test data once in the field, carries it through the lab without re-entry, runs the ASTM and AASHTO calculations automatically, and produces a signed, client-ready report from the same record.
In short:
Most CMT labs didn't choose paper and spreadsheets. They inherited them. A technician fills out a density form on a clipboard, someone in the office retypes it, a lab tech enters cylinder breaks into a spreadsheet, and an engineer assembles the final report in Word. Every handoff adds time and a chance for error.
The costs show up in five places:
As projects get larger and clients expect results in hours instead of days, those delays turn into lost work and non-billable time.
Digital reporting is a connected workflow where test data is captured electronically in the field, tracked through the lab, calculated automatically and published as a standardized report from the same record. It replaces disconnected paper forms, spreadsheets and word processors with one system of record.
A digital reporting platform for construction materials testing typically covers:
Aldoa connects each stage of CMT work so data moves forward instead of being re-entered.
Every step is timestamped, so the record of who collected, tested, reviewed and signed each result is built as the work happens.
Not every platform built for "field data" handles the full CMT workflow. Use these criteria when you compare options.

Digital reporting is a workflow where CMT test data is captured electronically in the field, tracked through the lab, calculated automatically and published as a standardized report. It replaces paper forms, spreadsheets and manual report assembly with one connected system.
Paper and spreadsheets force labs to retype data, recalculate results by hand and chase approvals, which slows turnaround and introduces errors. Digital reporting removes double entry, standardizes calculations and creates an audit trail automatically.
Yes, when the software uses standards-based calculations and templates. Aldoa includes preconfigured formulas for ASTM, AASHTO and DOT tests, plus report templates that can be configured to meet client, project or agency requirements.
Aldoa automates field density and compaction reports (nuclear gauge and Proctor), concrete compressive strength and cylinder break reports, aggregate and asphalt reports, special inspection reports with photo logs, and soil boring logs.
Yes. Aldoa's mobile forms work offline on phones, tablets and laptops, and data syncs to the office when the device reconnects.
A laboratory information management system (LIMS) tracks samples and tests from intake to final result. CMT labs use a LIMS to maintain chain of custody, assign lab work and connect results to reports. Aldoa's LIMS is built into the same platform as field data collection and reporting.
Most firms are running on Aldoa within weeks. Aldoa's onboarding team configures forms, rebuilds report templates and migrates existing projects and historical data, and the platform is cloud-based with no hardware to install.
Results vary by firm and report mix. CGC, a Wisconsin geotechnical and materials testing firm, cut the time it spends on reports by up to 75% after switching from paper to Aldoa.
In Aldoa, approved reports are generated as PDFs and delivered by email, predefined distribution lists, scheduled sends or a client portal, so clients get results as soon as they're signed.
