Concrete Monitoring Hardware

Real-time concrete strength and temperature monitoring.

SmartHub connects to cast-in probes to track concrete temperature and maturity-based strength from pour to sign-off.

SmartHub sensor installed on site

SmartHub is the reusable hardware layer of ConcreteAI's concrete monitoring system. It connects to cast-in probes, records concrete temperature history, and sends live data to the ConcreteAI platform for temperature monitoring and maturity-based strength estimation.

The probes remain embedded in the concrete. SmartHub stays outside the pour, is recovered after stripping, and can be reused on the next element.

Monitoring

What SmartHub monitors

SmartHub tracks the two concrete conditions that most affect early-age site decisions: temperature and strength gain.

Concrete Temperature

Temperature at selected depths, from the time of pour

Monitor temperature at selected depths or locations from the time of pour. Live trends help teams understand curing conditions, control temperature rise, track peak temperatures, and assess thermal gradients that may contribute to thermal crack formation in mass concrete elements.

Maturity-Based Strength

In-place strength gain, estimated in real time

Estimate in-place strength gain using the concrete temperature history and a project-specific maturity calibration. Strength trends help teams decide when to strip formwork, stress tendons, lift precast elements, or proceed with the next construction activity.

Step 5 · Optional · Strength validation only
SmartCure
Where physical strength evidence is required, SmartCure supports temperature-matched cube curing for validation and acceptance workflows. SmartHub feeds live concrete temperature to SmartCure, which adjusts its water bath so companion cubes cure under the same thermal conditions as the in-situ element.
Why this matters: Standard cubes cured at 20 °C consistently underestimate the strength of concrete that gained heat during hydration. SmartCure-cured cubes reflect actual in-situ strength, giving QPs a physically verified result alongside the maturity estimate.

Solutions

Built for multiple monitoring workflows

SmartHub is the reusable field device behind ConcreteAI's monitoring workflows. The data collected from site can support strength monitoring, mass concrete temperature monitoring, thermal crack simulation and analysis, and project reporting.

In-situ strength monitoring
Track maturity-based strength gain for stripping, post-tensioning, lifting, and demoulding workflows.
Mass concrete temperature monitoring
Monitor temperature rise, peak heat, and core-surface differentials during large pours.
Thermal crack simulation & analysis
Use actual site temperature data to validate thermal models, compare predicted vs measured heat profiles, and refine crack risk assessment.
Concrete data platform
Send live site data to the dashboard for alerts, reports, trends, and project-level visibility.

Built for real-time visibility

SmartHub sends site data to the ConcreteAI platform so project teams can monitor concrete temperature and strength trends as the pour develops. Live dashboards, alerts, and reports make concrete data visible when decisions need to be made.

Live platform visibility
Monitor concrete temperature and strength trends from the ConcreteAI platform without waiting for manual data retrieval.
Easy site installation
Install probes at selected locations before the pour, then mount SmartHub outside the formwork for access during monitoring.
Installed near the monitoring location
Place SmartHub close to the monitored element so probe cables are organised, protected, and easy to recover after stripping.
Wireless transmission
Send site data wirelessly through the Gateway to the ConcreteAI platform for live dashboards, alerts, and reports.
Reusable hardware
Recover SmartHub after stripping and reuse it on the next pour. Only the probe remains embedded in the concrete.
Multi-channel with backup logging
Connect up to four probe channels and continue recording locally when site connectivity is interrupted.
Applications

Where SmartHub is used

SmartHub can be used across concrete elements where temperature history, early-age strength gain, or thermal behaviour needs to be monitored from pour to completion.

Building structures
Monitor slabs, columns, walls, transfer structures, and post-tensioned elements for strength gain, temperature history, and cycle-time planning.
Precast production
Track early-age strength and curing conditions for demoulding, lifting, and production cycle optimisation.
Infrastructure and mass concrete
Monitor viaducts, bridges, tunnels, shafts, pile caps, rafts, and thick concrete elements where temperature control and thermal gradients matter.

What is SmartHub?+

SmartHub is a reusable concrete monitoring device. It connects to cast-in probes, records concrete temperature history, and sends live data to the ConcreteAI platform for temperature monitoring and maturity-based strength estimation.

Does SmartHub stay inside the concrete?+

No. SmartHub is mounted outside the formwork and recovered after stripping, then reused on the next pour. Only the probes remain embedded in the concrete.

How many probes can one SmartHub connect to?+

One SmartHub connects up to four probes simultaneously, covering different depths, locations, or structural elements within a single pour.

Can SmartHub be used for concrete strength monitoring?+

Yes. SmartHub estimates in-place strength gain using the concrete temperature history and a project-specific maturity calibration. Strength trends support decisions such as formwork stripping, post-tensioning, lifting, and demoulding.

Can SmartHub be used for mass concrete temperature monitoring?+

Yes. SmartHub monitors temperature rise, peak heat, and core-surface differentials during large pours. Probes can be positioned at the core, surface, edge, or other high-risk temperature zones.

Can SmartHub support thermal crack simulation and analysis?+

Yes. Actual site temperature data from SmartHub can be used to validate thermal models, compare predicted and measured heat profiles, and refine crack risk assessment.

What is required for a typical setup?+

A typical setup includes cast-in probes fixed before the pour, a SmartHub device mounted outside the formwork, a Gateway for wireless transmission, and access to the ConcreteAI platform for live dashboards, alerts, and reports.

Does SmartHub replace cube or cylinder tests?+

SmartHub provides maturity-based strength estimates that can reduce reliance on early-age cube or cylinder testing. Where physical strength evidence is required for acceptance, SmartCure supports temperature-matched cube curing alongside SmartHub monitoring.
