“…The device works with the ASCII protocol, which speeds up the integration of the reader into normal exploitation as needed [33,34]. This reader is designed to read and record UHF transponders EPC Class 1 Gen 2 (Figure 8) and communicate with various devices via USB communication channel and Bluetooth ® wireless technology [3,35]. Three transponders from Avery Dennison ® company have been selected for the experiment, solely focusing on the production of labelling elements such as RFID transponders.…”

Geopolymers are materials prepared from alkaline-activated cement without a calcium constituent. They are synthetic materials based on aluminosilicates. The main advantage of these environmentally friendly materials is that they save mineral resources and due to being free of calcium constituents, and only a small amount of CO2 emissions are released into the environment. The circular economy model of sustainable development of new composite materials will ensure the competitiveness of industries, their stable economic growth, and a healthy environment. This paper aims to investigate geopolymer composite materials that were reinforced with a mixture of glass powder from recycled windscreens. The glass 100% circulates in the closed material cycle and can be used again in the manufacturing process without any loss of quality. We are focused on verification of readability of selected automatic identification technology and their usability directly in the manufacturing process of geopolymer composite materials.

“…The results showed that the NSM method allows concrete beam higher failure strain, compared to the EBR method. There are also other available studies for shear strengthening, compression strengthening concrete structures or even CFRP/GFRP pre-stressed slabs/ beams at various temperature-mechanic testing conditions [27][28][29][30][31][32][33][34].…”

“…At a temperature of 100℃, the beam strengthened with alkali-activated siliceous system possesses nearly 33% higher loading capacity than that with the epoxy resin. Similarly, Zhang et al [13] compared the load-deflection behaviour of RC beams retrofitted with epoxy or geopolymer-bonded carbon FRP. The beam strengthened with geopolymer-based FRP achieves a better fire resistance as it exhibits a lower deflection than that with epoxy-based FRP.…”

Old Reinforced Concrete (RC) buildings are facing different degrees of structural deterioration and require proper strengthening to enhance their structural performance as well as to extend their life span. Fabric reinforced Alkali-Activated Slag (AAS) matrix is proposed to strengthen RC beams in this study. Seven RC beams with and without strengthening were prepared and tested under four-point bending. Test results indicate that use of AAS matrix as replacement for conventional cement-based matrix can change the failure mode of the strengthened beams from end-debonding of strengthening layer to slippage combined with rupture of fabric. The AAS-based strengthening strategy is able to enhance the loading capacity and flexural stiffness of RC beams as well as to reduce the strain of tensile reinforcements. Except the specimens failed in the premature debonding, increasing the fabric amount in the strengthening scheme improves the loading capacity of beams. In an optimal case, the yielding and ultimate loads of the strengthened beams are enhanced by 22.2% and 26.4%, respectively. Moreover, an analytical model was developed to predict the characteristic loads of the fabric reinforced AAS matrix strengthened beams. It shows that the analytical model could overestimate the yielding and ultimate loads of the strengthened beams, probably due to slippage and reduced synergistic effect of fabric bundles in the strengthening system. Based on that, two efficiency factors of 0.35 and 0.25, taking account of the area of effective fabric, are obtained and recommended to estimate the yielding and ultimate loads of fabric reinforced AAS matrix-strengthened beams, respectively.
