Reinforced Concrete Beams Strengthened with Externally Bonded Hybrid Fiber Reinforced Polymer Sheets: Experimental Studies , Kalyani Gurram, N. Pannirselvam, , M. Vinod Kumar, , S. Sundararaman, , J. Vanjinathan, , Ratna Rachel Ponraj, and Engineered Science, 2026 The performance of flexural supported and conventional RC beams that have been experimentally tested under static load are examined. Five beam specimens total are cast and tested; one remained as a control beam, whereas the other four were soffits retrofitted with Hybrid-FRP (HFRP) composite sheets/laminates, which are the combination of Aramid-FRP (AFRP) and Glass-FRP (GFRP). The maximum load-carrying capability obtained for the SH3 beam is 137.28% more than the control beam.
Microstructural and statistical analysis on mechanical performance of novel flattened end nylon fibre reinforced concrete M. Sridhar, M. Vinod Kumar, N. Nagaprasad, Suraj Kumar Bhagat, Krishnaraj Ramaswamy Scientific Reports, 2025 This study investigates the use of novel flattened-end nylon fibres (FENF) as reinforcement in concrete to improve its mechanical properties. The research addresses inadequate circumferential bonding between macro synthetic fibres and concrete matrix, which can lead to fibre slippage or failure. Through experiments involving 19 concrete mixes with varying fibre dosages (0.5%, 1% and 1.5%), aspect ratios (35, 55 and 75), and shapes (straight and flattened-end), the study examines the impact of FENF on concrete workability and mechanical strengths. The mechanical strength tests illustrate the significance of fibre dosage, aspect ratio and especially the shape as the compressive, split-tensile strength and flexural strengths of the FENF concrete are respectively showing an increase in strength of up to 10.3%, 25.1% and 26.1% when compared with conventional concrete. Similarly, the straight nylon fibre-reinforced concrete also achieved comparable strength increments up to 11.8%, 13.9% and 15.9% respectively for compressive, split-tensile and flexural strengths. This indicates that the positive effect of fibre shape on circumferential bonding helped the better performance of the FENF in split-tensile and flexural strengths. Further, the statistical methods, including regression analysis, Principal Components Analysis, and Response Surface Methodology, are employed to analyse the complex relationships between fibre characteristics and identify optimal fibre configurations. Using the Scanning Electron Microscope (SEM) the microstructural view has been studied to evaluate the interaction between FENF and the concrete matrix.
Discriminant covariate deep learning model for projecting of structural characteristics of hybrid fiber incorporated concrete beam retrofitted using GFRP M. Shyamala Devi, M. Vinod Kumar, S. Prakash Chandar, Mehmet Serkan Kırgız, N. Nagaprasad, Krishnaraj Ramaswamy Discover Applied Sciences, 2025 Advanced techniques for retrofitting reinforced concrete structures have emerged in response to the increasing demand for durable and environmentally friendly infrastructure. Previous studies have demonstrated that Hybrid Fiber Reinforced Concrete retrofitted with Glass Fiber Reinforced Polymers exhibits enhanced structural characteristics, including improved flexural strength, shear strength, and ductility. Despite several Finite Element Analysis studies, there remains a research gap in developing a machine learning model to predict these structural characteristics. For this research, a dataset was collected containing 27 attributes, comprising 18 independent variables and 9 dependent variables. The dataset was subjected to exploratory and prescriptive data analysis. The results indicate that the proposed Fused Learning Classifier Model achieves a high accuracy of 99% in predicting the structural characteristics of beams.
Investigation of bond strength and flexural behaviour of geopolymer aggregate concrete beams T. Udhaya Kumar, M. Vinod Kumar, Sivarama Krishna Lakkaboyana, Herri Trilaksana, Ahmad Ansari Case Studies in Construction Materials, 2025 The present study examines the bond strength and flexural behavior of geopolymer aggregate reinforced concrete beams, aiming to evaluate their potential as sustainable alternatives to traditional concrete. Geopolymer aggregates, produced from industrial by-products such as slag, offer an eco-friendly solution with a reduced carbon footprint. The experimental program includes a comprehensive series of tests on concrete beams reinforced with geopolymer aggregates, assessing their mechanical properties, bond strength between aggregates and reinforcing steel, and their flexural performance under loading conditions. For 10 mm reinforcements, geopolymer aggregate concrete has a bond strength increase of 3.2% and 4.4% compared to normal concrete, while for 12 mm bars, the increase is 2.4%. Ultimate load-carrying capacity in normal concrete is 15.6% higher than geopolymer aggregate concrete. Geopolymer aggregate concrete shows increased deflection at initial loading due to a lower modulus of elasticity, affecting crack control, but this is recommended for higher grades of concrete. Results indicate that geopolymer aggregate reinforced concrete exhibits comparable, if not superior, bond strength to conventional concrete. It is found that bond stress is increased up to 12% for geopolymer aggregate concrete than normal concrete. Additionally, flexural behavior analysis reveals enhanced performance characteristics, such as increased load-carrying capacity and ductility. These findings underscore viability of geopolymer aggregates in structural applications, promoting adoption of green materials in construction while maintaining structural integrity and performance.
Geopolymer Bricks Using Industrial Wastes to Reduce CO2 Footprint A. Chithambar Ganesh, R. Mohana, M. Vinod Kumar, V. Prem Kumar, Mehmet Serkan Kirgiz Handbook of Innovative Adhesive Technology Biodegradable and Cost Effective Binder for Built Environment and Engineering Sciences, 2025 The most commonly and widely used masonry units are bricks. Brickmaking is an energy-intensive operation that contributes significantly to air pollution through the liberation of CO2. The main objective of this chapter is to develop geopolymer bricks based on industrial waste under ambient conditions. The binding material used here is ground granulated blast furnace slag (GGBS) for the mixer of sodium hydroxide (SH) and sodium silicate (SS) solution as the alkaline enhancer. Iron slag is used as the fine aggregate. The key features that influence the properties of geopolymer bricks—proportion of GGBS and iron slag, ratio of SH(NaOH) and SS(Na2SiO3), and the molarity of NaOH solution—are optimized in this chapter. Brick tests are in accordance with IS 3495 (Part-2): 1992. This chapter aims to develop geopolymer bricks with qualities comparable to Class A first-class bricks with the least strain on the environment. This chapter would be beneficial in the arena of bricks and building materials.
Behavior of Bacterial Strain over Cementless Geopolymer Concrete for Sustainable Development A. Chithambar Ganesh, M. Vinod Kumar, A. Navya, G. Dasaradha Rami Reddy, S. R. Ragavi, C. Navin Gowtham, Mehmet Serkan Kirgiz Handbook of Innovative Adhesive Technology Biodegradable and Cost Effective Binder for Built Environment and Engineering Sciences, 2025 Many research works have thrown light on the utilization of bacteria in cement concrete, but only a few have investigated the influence of bacterial strain in the geopolymer concrete (GPC). GPC utilized in this discussion is based on ground granulated blast furnace slag (GGBS) and hence was cured under ambient conditions only. The key research objective of the current work investigates the effect of Bacillus subtilis and Bacillus sphaericus over the GPC in mechanical properties. The real contribution of bacterial strain in concrete can be witnessed in the self-healing property. Artificial cracks are induced in the GPC, and the self-healing mechanism is illustrated through the intermittent photographs. The findings claim the significant presence of bacterial precipitation, which heals the cracks completely. The research findings lay the path for the sustainable development of building materials.
