SmartCure automatically adjusts the curing tank temperature to follow the live temperature profile of concrete on site. Companion cubes are cured under the same thermal conditions as the structure, supporting early-age compressive strength testing for formwork striking, stressing, demoulding, lifting, and early loading decisions.
Standard-cured cubes are usually kept at fixed laboratory or ambient curing temperatures. In-situ concrete can heat up significantly during hydration, especially in large pours, precast elements, transfer structures, and high-cementitious mixes. Because early-age strength gain is temperature-dependent, standard-cured cubes may not represent the same temperature history experienced by the actual structure.
Temperature-Matched Curing, or TMC, is a recognised method under BS 1881:130 for curing concrete specimens to match the temperature history of the structure. SmartCure supports TMC workflows for projects referencing BS 1881:130 and BS EN / SS EN 13670 requirements for early-age concrete construction control.
SmartCure is ConcreteAI's temperature-matched curing system for concrete cube specimens. It receives live in-situ concrete temperature data from SmartHub, then automatically controls the curing tank water temperature so the cubes experience the same thermal history as the monitored concrete element.
SmartHub sensors monitor representative locations in the concrete element. SmartCure uses this live temperature profile to adjust the curing tank automatically throughout the early-age curing period.
Companion cubes are crushed by the testing lab using the usual compressive strength test workflow, but their curing temperature follows the selected in-situ concrete profile instead of a fixed standard condition.
Temperature history, tank matching records, cube details, and compressive strength test results are compiled into project reports for submission, review, and early-age construction decisions.
SmartCure fits into the normal concrete cube testing workflow, but replaces fixed-temperature curing with live temperature-matched curing from the monitored concrete element.
SmartHub sensors are placed at agreed monitoring points before casting. These points represent the concrete element or casting zone used for the early-age strength decision.
Companion cubes are prepared and placed into the SmartCure tank at the start of curing, as part of the normal project testing workflow.
SmartCure receives live in-situ temperature from SmartHub and automatically adjusts the water bath to follow the selected concrete profile.
At the required testing age, the cubes are removed, demoulded, and tested by the laboratory using the standard compressive strength test workflow.
Cube test results are supported by in-situ temperature history, SmartCure tank records, and matching data for QA/QC submission and early-age construction decisions.
SmartHub and SmartCure are complementary parts of the ConcreteAI early-age strength workflow. Both are based on the same monitored in-situ temperature history. SmartHub uses that history to calculate maturity-based strength values. SmartCure uses it to cure companion cubes under matched conditions.
SmartCure is used when early-age construction activities still require concrete cube test results, but the project team wants those cubes to follow the actual in-situ concrete temperature history. It is commonly used alongside SmartHub maturity monitoring, especially where physical cube evidence is required during adoption, approval, or transition periods.
Use SmartCure when formwork removal decisions require early-age strength results under curing conditions that match the monitored concrete element.
Use SmartCure when stressing decisions require compressive strength results under site-matched curing conditions.
Use SmartCure in precast production workflows where demoulding or bed turnover decisions depend on early-age strength results.
Use SmartCure when lifting, transport, or delivery decisions require strength evidence linked to the monitored precast element's curing temperature history.
Use SmartCure when temporary loading, access, or construction sequence progression requires early-age strength results.
Use SmartCure when teams want temperature-matched results alongside SmartHub maturity values before moving toward a fuller maturity-based monitoring workflow.

SmartCure connects to the ConcreteAI system via the same Gateway used by SmartHub. No separate wiring between structure and tank. The tank receives the live temperature signal wirelessly and adjusts automatically.
The tank operates on lockable wheels and is positioned in a sheltered location on site. It can be repositioned between bays or sites without specialist equipment. Full system setup takes under 10 minutes.

Common questions about temperature-matched curing, SmartCure, SmartHub integration, and early-age cube testing workflows.
The ConcreteAI team is available for technical questions before and during deployment.
Temperature-Matched Curing, or TMC, is a method where concrete specimens are cured to follow the same temperature history as the concrete structure. This helps cube test results better reflect the early-age curing conditions experienced by the actual element, rather than the cooler, fixed-temperature conditions of standard water curing.
SmartCure supports Temperature-Matched Curing workflows aligned with BS 1881:130. It also supports project workflows referencing BS EN / SS EN 13670 requirements for early-age concrete construction control. In Singapore, BCA issued circular APPBCA-2024-22 in December 2024 endorsing the use of TMC for early-age in-situ compressive strength determination.
Not necessarily. Standard 7-day and 28-day acceptance cubes may still continue according to project specifications — this is unchanged. SmartCure is typically used for early-age strength decisions where temperature-matched cube results are required, such as formwork striking, stressing, demoulding, lifting, or early loading. The two programmes run in parallel.
No. SmartCure and maturity-based monitoring are complementary. SmartHub provides continuous maturity-based strength values from the monitored concrete element. SmartCure uses the same temperature history to cure companion cubes under matched conditions, providing a temperature-matched cube test result alongside the maturity value. Both relate back to the same in-situ concrete temperature history.
SmartHub sensors monitor the in-situ concrete temperature profile from within the structure. That temperature data is transmitted through the ConcreteAI system and used by SmartCure to control the curing tank water temperature. The same temperature history can also be used for maturity-based strength monitoring through SmartHub.
Yes. SmartCure is suitable for precast production workflows where early-age cube results are used for demoulding, lifting, transport, or bed turnover decisions. Precast elements often experience elevated curing temperatures, so TMC results can be significantly more representative than standard-cured cube results. The cube demoulding and compressive strength test process remains unchanged — SmartCure changes only the curing condition.
