A temperature-controlled system that uses a measured concrete reference to adjust the curing environment of companion cylinders. Review the actual cylinder temperature history, moisture retention and break results under the plant’s approved procedure.
Connect the bed and companion cylinders
1. Measure the bedAgree on a representative concrete reference with QC.
2. Follow the temperatureReview cylinder temperature history and moisture retention.
3. Review the evidenceConnect the pour, temperature records and break results.
Photos illustrate separate plant installations and trial setups.
A reference measured in the concrete guides chamber temperature control. Compare the actual cylinder temperature with that reference and connect both records to the pour and break tests.
What to review before winter
Review concrete protection, probe placement, moisture retention, power and connectivity. Define who responds to temperature, power or data problems. Your QC team sets the evaluation criteria.
Match curing and standard curing
Standard curing and match curing serve different purposes. Standard curing supports the specified acceptance-testing program; match curing follows a pour reference for companion-cylinder evaluation. Keep the methods and tests required by the project.
What to confirm before choosing a system
Confirm chamber capacity and simultaneous profiles, mold sizes, operating range, temperature verification, data records, training and support. Supported mold sizes alone do not establish chamber capacity.
Standards, testing and release authorization
Specimen preparation and curing, compression testing and maturity estimation are different activities. Review the ASTM C31, C192, C39 and C1074 references applicable to your project with QC. The approved procedure and project authority determine how the evidence supports release authorization.
SensyCure: evidence to review
SensyCure connects a SensyCast bed reference with the companion-cylinder curing environment. On Day 2 of a documented trial, the average gap was 0.79°F and the maximum was 5.4°F. Review the conditions and results before defining your own trial.
Observed results from this trial, not a guaranteed tolerance. Review the protocol and charts.
What to confirm before your trial
- Reference and capacity: probe placement, simultaneous cure profiles, cylinder count and mold sizes.
- Installation: operating range for your location, power, connectivity and the response to lost power or data.
- Evaluation: moisture retention, temperature checks, break schedule, training and QC-approved criteria.
Frequently Asked Questions
What is a match-cure system?
A temperature-controlled system that uses a measured concrete reference to adjust the curing environment of companion cylinders. Review the actual cylinder temperature history, moisture retention and break results under the plant’s approved procedure.
Why does match curing matter in cold-weather precast production?
Companion cylinders can experience a different temperature history from the bed during cold weather. Match curing helps the plant evaluate cylinders under representative conditions; it does not heat or protect the production bed.
How accurately did SensyCure track the bed in the cold-weather trial?
On Day 2 of the documented two-day trial, the average temperature gap was 0.79°F and the maximum was 5.4°F. These observations describe that trial, not a guaranteed tolerance for every installation.
What should a plant confirm before a winter match-cure trial?
Confirm reference placement, cylinder count, mold sizes, operating range, power, connectivity, moisture retention, temperature checks and the QC-approved break schedule. Agree on training, support and the records used to evaluate the trial.
Does match curing replace cylinder breaks or standard-cured acceptance tests?
No automatic change to the testing program is implied. Match curing controls the companion-cylinder environment. Keep the breaks, acceptance tests and verification required by the specification and approved quality plan.
Which standards and approvals should QC review?
Review the applicable editions and requirements for specimen preparation and curing, compression testing and maturity estimation. References may include ASTM C31, C192, C39 and C1074. Confirm the accepted release procedure with the project authority; a standards reference does not establish equipment certification or blanket DOT approval.
