“…Thermistors are used for long-term monitoring of concrete structures, providing valuable data for assessing the remaining service life of structures. Data collected by thermistors are used to predict potential failures in concrete structures and enable maintenance before the actual failure [94]. Thermistors, due to their high sensitivity, low cost, small size, and non-destructive nature, are often used in concrete structures as a sensor.…”

Structural health monitoring (SHM) is crucial for maintaining concrete infrastructure. The data collected by these sensors are processed and analyzed using various analysis tools under different loadings and exposure to external conditions. Sensor-based investigation on concrete has been carried out for technologies used for designing structural health monitoring sensors. A Sensor-Infused Structural Analysis such as interfacial bond-slip model, corroded steel bar, fiber-optic sensors, carbon black and polypropylene fiber, concrete cracks, concrete carbonation, strain transfer model, and vibrational-based monitor. The compressive strength (CS) and split tensile strength (STS) values of the analyzed material fall within a range from 26 to 36 MPa and from 2 to 3 MPa, respectively. The material being studied has a range of flexural strength (FS) and density values that fall between 4.5 and 7 MPa and between 2250 and 2550 kg/m3. The average squared difference between the predicted and actual compressive strength values was found to be 4.405. With cement ratios of 0.3, 0.4, and 0.5, the shear strength value ranged from 4.4 to 5.6 MPa. The maximum shear strength was observed for a water–cement ratio of 0.4, with 5.5 MPa, followed by a water–cement ratio of 0.3, with 5 MPa. Optimizing the water–cement ratio achieves robust concrete (at 0.50), while a lower ratio may hinder strength (at 0.30). PZT sensors and stress-wave measurements aid in the precise structural monitoring, enhanced by steel fibers and carbon black, for improved sensitivity and mechanical properties. These findings incorporate a wide range of applications, including crack detection; strain and deformation analysis; and monitoring of temperature, moisture, and corrosion. This review pioneers sensor technology for concrete monitoring (Goal 9), urban safety (Goal 11), climate resilience (Goal 13), coastal preservation (Goal 14), and habitat protection (Goal 15) of the United Nations’ Sustainable Development Goals.

“…Pre-formed foam is widely used in foam concrete production to introduce air-voids, creating lightweight concrete (7,8,10,11,(13)(14)(15)(16)43). Several foam agents, such as sodium dodecyl sulfate (SDS), stabilized with hydroxypropyl methylcellulose (HMPC) and wet-ground limestone powder, achieved a foam density of 50 kg/m3 using an ultrasonic instrument (16).…”

This document provides a contemporary overview of a wide array of aspects concerning foam concrete and its inherent properties. This review covers topics such as the use of alternative binders, the influence of water/cement ratio, fine aggregate replacements and an examination of mechanical properties. By meticulously scrutinizing compressive strength data from multiple authors, this exploration not only highlights the current state of knowledge but also underscores the potential for future investigations in the realm of foamed concrete. Similarly, this examination realizes the limitations that the unique structure of foamed concrete imposes on diverse applications in construction and engineering.

“…Classified as lightweight, foam concrete is a cellular type of concrete (LCC) with a density range of 300–1600 kg/m 3 . The role of density is important in terms of strength and thermal conductivity, which was studied by Compaoré et al [ 10 ]. Although the decrease in density results in a decrease in strength, the research indicates the reduction in this phenomenon due to enhancement in the growth of amorphous and recrystallized phases inside the air voids.…”

Lightweight concrete exhibits many advantages over traditional concrete such as lower density and thermal conductivity and an easier, cheaper, less energy-consuming manufacturing process. In order to extend its applications, there is a need to study its behavior in fire situations. Due to that, the aim of this study was to assess the fire resistance of foam concrete, depending on its thickness and the foaming process applied. Fire resistance was assessed according to EN 1363-1. The results indicate the usefulness of foam concrete in terms of isolating fire temperatures for discontinuous partition filling that are consequently a real alternative to dedicated solutions in the field of passive fire protection. The density of foam concrete was shown to have a large effect on the ability to insulate fire temperatures with a standard material preparation process. It was also noted that changing the method to continuous foam feeding may result in the achievement of similar values while maintaining foam concrete low density.
