The major problem of concrete is the development of cracks, this paper concentrates on increasing the tensile strength of concrete and preventing the cracks present in the concrete by retrofitting geotextile material. Concrete beam specimens are casted and cured for a particular period of time.

CHALLENGES IN CONVENTIONAL CONCRETE:

After curing period is done with the help of epoxy chemical, we have done the retrofitting process to the concrete by using Geotextile. And then we are comparing the strength of normal concrete and geotextile concrete. Concrete being major components in construction industry and it is a hard chemically inert material which is good in compression but weak in tension. The major problem of concrete is the development of cracks. Concrete beam specimens are to be casted with wrapping of geotextile. The selecting strengthening materials, the material must have bonding properties with the existing structure and sufficient sustainability should exist in terms of strength, durability, and cost. woven polypropylene geotextile fabric is selected for this project. content to maintain a seamless integration with the real world. Integration with the Physical Environment: AR applications are designed to align and interact with the user's physical surroundings. Digital elements are spatially mapped to correspond with real-world objects, creating a cohesive and immersive experience. 

 

IMPORTANCE OF GEOTEXTILE IN CONVENTIONAL CONCRETE:
Geotextiles play a significant part in modern pavement design and maintenance techniques. Geotextiles are ideal materials for infrastructural works such as roads, harbours, and many others. Generally, they have properties of high performance under load, cracking resistance, availability, high workability, and cost effectiveness. Such strengthened beams are expected to have high tensile strength, high ductility ratio, enhanced energy absorption capacity, and reduced crack width with large deflection resistance up to failure. Woven polypropylene geotextile concrete reduces the water penetration into the RC structure when used as protective layer. These materials are cost effective and locally available in rural areas and are thus genuinely sustainable. Geotextile material wrapping is the latest strengthening/enhancement technology for reinforced concrete and masonry structural members. It is used for flexural, shear or confinement strengthening of structural members. And ensure minimum disturbance to the structural members as compared to other conventional methods.by wrapping technology, the cracked beam has been wrapped with geotextile material in two layers by applying Epoxy resin.

 

ILLUSTRATION AND COMPONENTS OF GEOTEXTILE: 

 

From simple augmentations, like informational pop-ups, to more complex and interactive scenarios, such as gamified applications or training simulations. Understanding these principles is crucial for the successful development and implementation of AR applications across various industries, including gaming, education, healthcare, manufacturing, and, as discussed, inventory management. 

 

In the contemporary backrooms of Retail Stores, effective inventory management stands as a critical determinant of success for enterprises across diverse industries. Traditional inventory management systems often grapple with challenges related to accuracy, efficiency, and adaptability, calling for innovative solutions to optimize supply chain processes. This paper explores the integration of Augmented Reality (AR) technology as a transformative approach to address these challenges and redefine the cost-effectiveness paradigm in inventory management [8] which can also be achieved through IoT and AI [7]. Specifically, it explores the idea of using AR solution to identify which boxes need to be stocked or moved from backroom to the salesfloor. The advent of AR, with its ability to overlay digital information onto the physical world, presents an unprecedented opportunity to revolutionize how businesses monitor, track, and manage their inventory. This paper aims to elucidate the theoretical framework supporting the integration of AR in inventory management, delve into the methodology employed in designing and implementing an AR-based system, and present the results of simulations and case studies evaluating the system's impact on accuracy, efficiency, and cost-effectiveness [9].

ADVANTAGES OF GEOTEXTILE OVER CONVENTIONAL CONCRETE:

 

The M30 concrete beams are casted and cured for a particular period of time. Then, the beam specimens are tested for flexural strength. Followed by retrofitting of the beams by wrapping the geotextile material with the help of epoxy resin. Finally, the retrofitted beams were tested and the value of flexural strength is compared with normal beam. The retrofitted beam was found to have a greater flexural behaviour even after the cracking of the beam hence geotextiles can be adopted as a best material for retrofitting in concrete structures. The casting of beam has been done by the (M30) designed mix ratio of concrete. The arrived mix ratio of 1:1.9:2.8 The beam casted with proper compaction. After that the casted beams were cured for 28 days. After the curing period the beam specimens are kept for the flexural strength test until the formation of minor cracks and the flexural strength readings are noted. Then the geotextile wrapping process can be done in the beam specimen with the cracked beams. The retrofitting of concrete should be done for the cracked beam specimens. The retrofitting process is done by wrapping the beam with the help of geotextile sheet and the epoxy resin. 

Retrofitting Process

Finally, the retrofitted beam specimens are tested in the universal testing machine by placing the beam centrally in the testing machine and the flexural strength readings are noted and compared with the normal conventional concrete to the retrofitted concrete
