The ConcR Box employs Nordic Semiconductor’s nRF9160 SiP to transmit data to the Cloud via cellular IoT connectivity
German company ConcR GmbH has launched a smart building material monitoring solution that analyzes the physical attributes of concrete as it dries and “matures”, to check when it is safe to proceed with the next stage of construction. The solution provides data across the life cycle of cementitious building materials like concrete and screed starting from construction until 25 years in operation, enabling data centric insight within each lifecycle phase for planners, engineers, contractors, and owner-operators.
The ‘ConcR Sensors’ are attached to a rebar (a reinforcing steel bar used to strengthen concrete slabs) before the concrete is poured. The sensors are connected to the ‘ConcR Box’, which sends the data – collected every ten minutes – directly to the Cloud. This solution can record temperature, relative humidity, residual moisture, pH and chloride levels, providing key insights into the strength and durability of the cement or concrete.
“These physical attributes are vital from a civil engineering perspective,” says Burak Acilan, Founder and CEO at ConcR GmbH. “Without the validation that the concrete poured on-site meets the required technical specifications, construction cannot proceed. This makes ConcR solution ideal not only for quality monitoring, but also for project management.”
