Smart Concrete Sensors

SmartRock2™ is a rugged waterproof wireless sensor that allows real-time temperature and maturity monitoring of concrete. The sensor is placed in the concrete formwork (installed on the rebar) before pouring.

Smartrock 2 sensors are tied to reinforcing steel within the slab or formwork which enables wireless and continuous monitoring of concrete temperature and strength. This is critical to achieve the design life of the concrete structure. The sensor uses Bluetooth technology to transmit data that can be read with an Android IOS smartphone app. The app draws on data stored in the cloud to analyse the performance of the concrete.

Smartrock 2 has several benefits. One MAJOR advantage is the optimization of the concrete formwork removal cycles. The smart sensors will provide updates on the strength and humidity of the concrete which can possibly lead to the formwork being removed earlier than anticipated. This would therefore push the construction programme ahead and ultimately the project could be delivered earlier, saving valuable man hours.

Typically field technicians cast test cylinders which are sent to labs for analysis. However the concrete in the cylinder may not share or show all of the properties within the concrete that has been placed. This is due to variables such as temperature, weather or improper casting and storage. For contractors using this new sensor technology they know in real time if their concrete has reached the desired strength.

Tag sensor

Label the sensor with the tag indicating its location both on the sensor and in the mobile app.

Install sensor

Once onsite, attach the SmartRock2 sensor to the rebar by twisting the metal wires together. This will activate the sensor, measuring concrete temperature and strength.

Pour concrete

After installing the sensor in the formwork, pour concrete as usual.

Obtain results

At any time, wirelessly connect to the SmartRock2 sensor, and view the temperature and strength.

Giatec BlueRock™ is a rugged waterproof sensor for wireless monitoring the relative humidity and temperature of concrete from fresh stage to hardened stage.

BlueRock™ can be placed in the concrete at the pourig time to monitor the temperature and humidity of concrete in-situ. The continuous measurements are recorded on the BlueRock™ memory and can be downloaded at any time during the concrete setting and hardening using BlueRock™ mobile app on smartphone/tablet.

The continuous monitoring of concrete relative humidity and temperature can be used as a QC/QA method. Knowing the level of humidity in the concrete, flooring companies can decide on the timing of installation of floor covering (such as resilient flooring, epoxy coating, or wood) based on the type of concrete materials. Unlike the current time-consuming methods that measure only one data point at the testing time through drilling a hole in concrete, BlueRock™ offers and embedded wireless solution for continuous measurement and accurate monitoring of humidity variations in concrete over time.
