“…For the sensors validation, the common cement screed CT‐C25‐F4 according to DIN EN 13813 36 and DIN 18560 25 was used. By the additional placement of a climate data logger from Trotec (model BL30), it was possible to detect temperature fluctuations or humidity changes of the environment.…”

The advancing digitalization is changing almost all areas of society and drives rapid innovation. The construction industry provides many fields of application with numerous opportunities for improvement of efficiency. Accordingly, there are chances and threats caused by digital change at present. The main challenge is the extreme wide range of topics and tasks in all phases of the value chain-development, design, construction, and operation-concerning hardware and software. The aim of this study is to evaluate, if digital sensors can be helpful for an enhanced construction. In a first study for an application field, the authors pointed out the moisture content of structures, because this is a comparatively clear but also crucial point in construction process. In specific, a new digital sensor system for the moisture measurement in screed is being developed and evaluated. The achieved results show general feasibility of digital sensors to improve the construction process and motivate for further studies in this research field.

“…The structural health of concrete members relies on several factors, including temperature (both external and internal), humidity, moisture content, applied stresses and boundary conditions during manufacturing and its life cycle (Strangfeld et al , 2017; Tran et al , 2017). Structural members’ design normally takes these factors into consideration (Ghodoosi et al , 2018).…”

PurposeThis research paper adopts the fundamental tenets of advanced technologies in industry 4.0 to monitor the structural health of concrete beam members using cost-effective non-destructive technologies. In so doing, the work illustrates how a coalescence of low-cost digital technologies can seamlessly integrate to solve practical construction problems.Design/methodology/approachA mixed philosophies epistemological design is adopted to implement the empirical quantitative analysis of “real-time” data collected via sensor-based technologies streamed through a Raspberry Pi and uploaded onto a cloud-based system. Data was analysed using a hybrid approach that combined both vibration-characteristic-based method and linear variable differential transducers (LVDT).FindingsThe research utilises a novel digital research approach for accurately detecting and recording the localisation of structural cracks in concrete beams. This non-destructive low-cost approach was shown to perform with a high degree of accuracy and precision, as verified by the LVDT measurements. This research is testament to the fact that as technological advancements progress at an exponential rate, the cost of implementation continues to reduce to produce higher-accuracy “mass-market” solutions for industry practitioners.Originality/valueAccurate structural health monitoring of concrete structures necessitates expensive equipment, complex signal processing and skilled operator. The concrete industry is in dire need of a simple but reliable technique that can reduce the testing time, cost and complexity of maintenance of structures. This was the first experiment of its kind that seeks to develop an unconventional approach to solve the maintenance problem associated with concrete structures. This study merges industry 4.0 digital technologies with a novel low-cost and automated hybrid analysis for real-time structural health monitoring of concrete beams by fusing several multidisciplinary approaches into one integral technological configuration.

In order to design a robust passive temperature sensing tag that can operate over a wide temperature range, temperature-sensitive characteristic of UHF radio frequency identification temperature sensing chip and corresponding tags are studied. The devices under test include dipole tags with different antenna impedances. Simulation data, experiment design, system setup, measurement procedures, and test results are given. The results show that as temperature increases, the real part of chip impedance increases, and the absolute value of the imaginary part decreases, which are consistent with simulation data. In the full temperature range, the overall performance of sensing tags designed for high-temperature conditions is better than tags designed only for room temperature conditions.
