The rise in the rebar temperature impact the quality, strength and durability of the concrete. It is difficult to observe the raise or fall of the rebar temperature by naked eye. This paper focused on instrumentation used in civil structures. The intention of using the instrument in structural members is to fetch the behavior and characters of the structure based on external as well as internal factors. The sensors used in construction industry are classified in to parametric and self-generating types. A transducer is a device that converts one type of energy to another. From a secondary data that is publication, journals and related sources it is captured that the instruments are assisting the human beings through data fetching and sharing for future application/ correction/ to adopt the preventive mechanism. It presents a real-time, remote monitoring system for tracking rebar temperature in concrete structures using an integrated suite of advanced instruments, including Infrared Thermometers, Type K Thermocouples, Embedded Sensors, and Digital Data Loggers. The innovative aspect lies in the strategic deployment of these devices at critical structural locations and their synchronized use to correlate rebar, ambient, and mix temperatures throughout all stages of concrete placement. This method enables predictive and preventive control of thermal gradients and hydration heat, directly contributing to improved structural integrity, quality assurance, and extended service life of reinforced concrete members. Furthermore, the system's cost-effective, non-intrusive design, combined with defined sensor placement protocols and logging intervals, positions it as a practical advancement in construction monitoring and lifecycle management. The sensors or thermocouples shall be placed at critical spots like top mat, bottom mat, sunlit areas and shaded areas. Attach thermocouples securely with heat-resistant tape or steel ties, avoiding insulation between the sensor and steel. At least one sensor per 10-20 m² is recommended. It is recommendable to correlate rebar temperature with ambient temperature and concrete mix temperature for quality purpose. With this instrumentation the temperature of the rebar may be controllable, in turn it yields the high-quality structural member. The value of the member is also enhanced and also the life of the member will serve for the design life.
Concrete durability is a paramount concern due to its, direct impact on the infrastructure longevity and structural integrity. Rapid chloride penetration and electrical resistivity are pivotal parameters for assessing durability, where chloride ingress leads to reinforcement corrosion and resistivity reflects pore connectivity and moisture content. This study investigates the efficacy of diverse fiber blends and curing compounds in bolstering concrete durability, employing the Electric Resistivity Test and Rapid Chloride Penetration Test (RCPT) for evaluation. Through a comprehensive literature review and experimental exploration, various fiber types, proportions, and curing compounds were scrutinized. Concrete specimens reinforced with 0.66% Steel fibers, SF 0.36% + 0.3% GF, SF 0.36% + 0.3% PPF were cured with different compounds and tested for chloride penetration and electrical resistivity. Results unveiled the substantial decrease of chloride penetration and electric resistivity in fiber-reinforced concrete compared to plain concrete is approximately 25% and 65% respectively. Amongst all the curing compounds used Fosroc concure 1315 and Razon CCC 105 ACY exhibits best results.
The construction industry relies on a variety of structural materials, with concrete being a favored choice due to its outstanding strength and durability. Conventional concrete is typically made up of cement, fine aggregates, and crude aggregates, with its strength designed to meet specific requirements. Enhancing sustainability and minimizing environmental impact can be accomplished through utilizing waste substances in concrete production. One approach involves partially replacing cement and fine aggregates blended with waste glass powder. Additionally, superplasticizers serve as commonly utilized to lower the water-cement ratio (F/C), thereby improving the power properties of concrete. Effective curing remains a crucial factor in augmenting structural durability and concrete's mechanical characteristics in structures. The study examines strength and durability characteristics of concrete from integration using glass powder in place of certain cement and fine aggregate. Cement-based material mixtures are prepared with two different w/c values of 0.4 and 0.5 and replacement concentrations of 10%, 15%, and 20% for both the binder and fine aggregates. Essential parameters include fast chloride permeability and water absorption; comparative analyses are conducted to determine performance differences between conventional concrete and the modified version. The results of assessing the viability of adding leftover glass powder to concrete, this study aims to improve environmentally friendly building techniques.
The race to net-zero emissions and resilient infrastructure has spurred rapid innovation and demands urgent transformation in structural engineering. This review synthesizes recent advances in AI-driven design, modular construction, green materials, 3D concrete printing, and lifecycle/digital tools for sustainable structures. The author surveys state-of-the-art methods and case studies, quantifying environmental benefits and highlighting adoption barriers. In AI-based design, generative and machine-learning algorithms explore vast design spaces, yielding lighter and more efficient structures than traditional methods. Modular and prefabricated systems demonstrate dramatic schedule acceleration (e.g., a Hong Kong modular hospital built in four months) and 10–21% reductions in embodied carbon compared to conventional construction. Wood and other bio-composites (e.g., mass timber, bamboo, mycelium) are shown to sequester carbon and cut global-warming potential by >25% versus concrete materials.While advanced bio-based insulation materials offer low embodied energy. 3D concrete printing enables material and form optimization, reducing waste and formwork needs and showing lower life-cycle GHG emissions for simple structural elements. Finally, integrated life-cycle assessment (LCA) and digital twins/IoT monitoring allow real-time optimization of energy use and maintenance, further curbing carbon footprints. The author discusses cross-cutting challenges (data requirements, codes/regulations, and material durability) and proposes future directions. This comprehensive review underscores how converging technologies can reshape future skylines into greener, more efficient designs and outlines pathways for their wider implementation.
Significant structural collapses happen when a structure is exposed to dynamic loads, such as wind and earthquake loads. The majority of contemporary buildings include architectural meaning, which makes regular form planning extremely challenging. When dynamic loads cause a building to collapse, these anomalies are to blame. It is recommended that all structural analyses be carried out using the ETABS software package to accurately obtain displacement values and other structural responses. With the literatures the current study summarizes the Marcos 3-D of G+20 floors with asymmetric vertical configuration starting on the ninth level and symmetric lifting arrangement throughout its height determining the answers of every prior table for every possible combination of loads. The dynamic analysis is authorized by IS 1893 (Part 1): 2016, and the response spectrum analysis method is recommended to determine the lateral forces and shear demands on the floors of the three building models resulting from seismic loads (analysis of linear dynamics). The impacts of dough inconsistency and vertical irregularity under dynamic stresses in multi-story buildings were highlighted in this study. Three reinforced concrete (RC) building frames have been selected for the study, and it is recommended that each frame be individually modeled and analyzed in detail.
