CLOUD-BASED SOLUTION TO CONCRETE MATURITY MONITORING
The SmartRock wireless sensors offer a simple, cloud-based solution to concrete maturity monitoring in accordance with ASTM C1074. In an industry that’s still heavily dependent on traditional strength testing methods (i.e. cylinder breaks)—which are destructive, slow, expensive, and often unreliable—SmartRock aims to introduce more efficient and environmentally friendly alternatives to concrete testing.
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.
Label the sensor with the tag indicating its location both on the sensor and in the mobile app.
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.
After installing the sensor in the formwork, pour concrete as usual.
At any time, wirelessly connect to the SmartRock2 sensor, and view the temperature and strength.
