1.	Corrosion Assessment in Reinforced Concrete Structures using Structural Integrity Monitoring and the Finite Element Method Victória Góis, Lucas Gomes Raquel Silva International Journal of Advances in Engineering & Technology (IJAET), Volume 18 Issue 3, pp. 79-90, June 2025. ABSTRACT This study investigates the effective application of Structural Health Monitoring (SHM) to detect the onset of corrosion in reinforced concrete structures, using the electromechanical impedance (EMI) technique. Considering that corrosion develops slowly and often imperceptibly, an accelerated method, known as the impressed current technique, was used to simulate deterioration. In this context, an electrochemical potential was applied to steel bars immersed in concrete specimens submerged in saline solution, reproducing aggressive environments. Piezoelectric sensors made of lead zirconate titanate (PZT) were used to monitor the progression of damage. These sensors are able to record minimal mechanical changes in the structure, converting them into variations in electrical impedance. By monitoring these impedance signatures, it was possible to assess the progression of corrosion, as well as to quantify its effects on the structural integrity of the concrete. In parallel with the experiment, numerical simulations were performed using the Finite Element Method (FEM) to simulate the behavior of the materials and the progression of damage. This dual approach enabled the evaluation and deeper interpretation of the practical results. The results demonstrate the high sensitivity of the EMI technique in the early identification of damage. Together, the practical and computational analyses provide valuable data on corrosion processes, enabling the creation of more intelligent and preventive maintenance strategies, increasing the durability, safety and performance of concrete structures exposed to aggressive environments.	79-90	Online
2.	Study of Magnesium Oxysulfate (MOS) Matrices Reinforced with Fiberglass and Limestone Filler for Applications in Civil Construction Kalita C. Araujo, Antonio P. Peruzzi, Carlos E. M. Gomes International Journal of Advances in Engineering & Technology (IJAET), Volume 18 Issue 3, pp. 91-102, June 2025. ABSTRACT This study evaluated Magnesium Oxysulfate (MOS)-based matrices reinforced with AR glass fibers and limestone addition for applications in civil construction. Examined how the use of fiberglass and limestone affected the mechanical and physical characteristics of MOS and the adhesion between matrix-fiberglass in this composite aiming for the Dimensional Stabilization of the composite, reducing its propensity to cracking, and reducing the final cost of the composite. Mechanical and Physical assays were performed and observations by SEM on samples cured at room temperature. The results showed that the addition of limestone content, above a certain quantity, improves the behavior of the MOS increasing its Flexural Strength, was beneficial for the Dimensional Stabilization of the composite, reducing its propensity to cracking, but high levels of limestone compromised the mechanical properties of the composite, due to the reduction of the Molar Ratio and the inert behavior of the limestone. Substitution levels between 10% and 20%, the pores formed acted to relieve internal tensions generated by the expansion of MgO, resulting in an improvement in Flexural Strength. The addition of fiberglass, proved to be effective in controlling shrinkage, preventing the formation of cracks and increasing tensile and Flexural Strength, like the behavior observed in Portland cements.	91-102	Online
3.	Sizing Aspects of Fluid Concrete Beams Reinforced With Fibers Iva Emanuelly Pereira Lima and Aline Silva Ramos Barboza International Journal of Advances in Engineering & Technology (IJAET), Volume 18 Issue 3, pp. 103-115, June 2025. ABSTRACT The use of FRC for structural purposes has been gradually increasing and this growth has resulted in the emergence of standards such as the fib Model Code. This standard represents the calculation aspects for dimensioning FRC elements, however, the dimensioning steps are not fully illustrated. Thus, and to contribute to these steps, this work aims to determine an equation for the tensile stress of fibers for FRC beams. For this purpose, situations of sections reinforced with fibers and reinforcement (combined situation) and sections reinforced only with fibers were analyzed. Then, the values determined by the equation proposed in this work were compared with those stipulated in accordance with the fib Model Code. Thus, it was verified that for the combined situation, the values did not present significant discrepancies, however, for the section reinforced only with fibers, the variations were more discrepant, showing that the methodology proposed presents a conservative aspect. It is worth mentioning that, when using the equation proposed in this work, the tension value will present a conservative aspect and, although this work cannot be adapted to all situations of FRC structural elements, it is clear from the investigation that there may be an influence of the methodology used to obtain the tensile stress of the fibers, which demonstrates future perspectives for new work on the subject.	103-115	Online
4.	Effect of Different Cements with Fly Ash on Def Occurrence Over Time Francieli Tiecher; Nicole Pagan Hasparyk; Luriane Zago Perondi International Journal of Advances in Engineering & Technology (IJAET), Volume 18 Issue 3, pp. 116-131, June 2025. ABSTRACT This study reports an experimental program involving delayed ettringite formation (DEF) of composites with several pozzolanic cements. Mortars were prepared using a standard mix in the presence of 6 cements. DEF was induced by thermal curing (Peak of 85ºC). Laboratory assessments included expansion measurements, mechanical properties, and microstructural analyses. Results indicate that pozzolanic cements produced less damage from DEF in comparison to a cement with no pozzolan. Whereas mortars containing pozzolanic cements showed less expansions ranging between 0.10% and 0.20%, reference mortar (with no pozzolan) exhibited larger expansions, up to 0.40%). Nevertheless, the level of expansion and negative impacts on mechanical properties proved that DEF was not able to be mitigated. Furthermore, pozzolans appeared just to delay damages from DEF. The use of pozzolans in the production of Portland cements contributes to a reduction of cement and, thus, CO2, and must be considered in the mix designs of concretes improving durability in front of external agents. Nevertheless, studies on hydration heat of cements, prediction of internal temperature of concrete and also limitation of curing temperature must be considered before concrete placement in structures to avoid risks of thermal cracking and also an internal sulfate attack by DEF.	116-131	Online
5.	Voice-Assisted AI Systems for Inclusive Railway Booking Aditya Prabhaker, Mehul Khanna, Sumit Nayak, Deepak Kumar Panda International Journal of Advances in Engineering & Technology (IJAET), Volume 18 Issue 3, pp. ....., June 2025. ABSTRACT Artificial intelligence (AI) and speech recognition technologies are developing at an unprecedented rate, which offers a unique opportunity to improve the accessibility and inclusivity of train ticketing systems. The purpose of this project is to investigate the development and use of voice-assisted artificial intelligence systems that are especially designed to improve the experience of using for elderly, disabled, and low-tech individuals. Through the use of artificial intelligence (AI) and natural language processing (NLP), this study suggests a framework that enables users to make simple voice requests for booking tickets, checking timetables, and making enquiries. Because of its multilingual nature, the system is inclusive of users from a variety of language backgrounds. A thorough assessment was carried out, with a special emphasis on the system's accuracy, usability, and accessibility for older and visually impaired users. The findings indicate that railway ticketing systems with voice assistance have the potential to drastically lower obstacles to accessibility, encourage digital inclusion, and improve the overall ease of train services. Along with discussing these technological issues, this article offers methods to solve the constraints in user authentication, scalability, and accuracy of voice recognition. The results imply that voice- assisted technologies are not only feasible but also essential to building a more accessible public transit system.	.......	Online
