Integrated experimental, machine learning, and life-cycle assessment of fly ash–silica fume based self-compacting geopolymer concrete Siva Shanmukha Anjaneya Babu Padavala, Siva Avudaiappan, Sri Ram Ravi Teja Prathipati, Yeswanth Paluri, Vanakuri Sainath, Adamu Mulatu Kumara Scientific Reports, 2026 This study investigates the performance of self-compacting geopolymer concrete (SCGC) incorporating fly ash (FA) and silica fume (SF) as aluminosilicate precursors, with emphasis on mechanical behaviour, durability, microstructural characteristics, environmental impact, and machine-learning-based performance prediction. Four geopolymer SCC mixes were prepared using SF to substitute FA at 0, 5, 10, and 15% by weight and an OPC-based SCC of the same class of strength was prepared to serve as a benchmark. Fresh properties were assessed as per EFNARC standards after which compressive, split tensile and flexure strength were done at intervals of 28, 90, and 180 days. Sorptivity, rapid chloride permeability (RCPT) and ultrasonic pulse velocity (UPV) were used to determine durability, whereas scanning electron microscopy (SEM) was used to measure the microstructural evolution. Findings reveal that SF is a considerable improvement to fresh and hardened geopolymer SCC, the best performance being found at a 10% replacement. The G10 mix recorded the best compressive strengths of 65.3 MPa at 180 days, which was 21% higher than the FA only geopolymer mix, and tensile and flexural strengths were 14–18% higher compared to FA only geopolymer mix. The performance of durability increased significantly, as sorptivity was reduced by about 21% and RCPT was lower than 1000 Coulombs (extremely low permeability) and the largest values of UPV were the highest, which shows the presence of a dense and uniform internal structure. Refined pore structure and well-developed the formation of aluminosilicate gels in the G10 mix had been confirmed by SEM observations. Parameters of mix, fresh properties, and curing age were used as inputs to develop machine learning models (KNN, SVM, Decision Tree, and Random Forest). Among them the predictive accuracy of the Random Forest model (R2 = 0.94) with the least error showed excellent performance forecasting and mix optimization. It was found by Life Cycle Assessment (LCA) that geopolymer SCC mixtures had less environmental impact through global warming potential (30–45% less than OPC-SCC) and energy (around 20–25% less than OPC-SCC) and the G10 mix had the lowest environmental impact. Overall, the study demonstrates that FA–SF geopolymer SCC with 10% SF replacement provides a good combination of workability, strength, durability, and sustainability that is proven in experimental, microstructural, data-driven modelling, and environmental analysis.
Influence of Geometrical Parameters on Local Buckling in Steel I-Sections Hanuma Kasagani, Praveen Oggu, S. R. R. Teja Prathipati, B. Murali Krishna, Srikanth Koniki Journal of Structural Design and Construction Practice, 2026 The width/depth to thickness ratio (b/t or d/t) for compression elements is specified by current Indian building standards to prevent local buckling. The limiting depth to thickness ratio is low for flanges due to its unstiffened nature, which is difficult to maintain practically (i.e., most of the sections become slender sections). Slender sections that are prone to buckle locally are generally avoided in design. In this study, an investigation is carried out to make the flange (slender elements) stiffened by providing lipping along the longitudinal edges of the flange, similar to that of cold-formed sections, so that local buckling of the flange is avoided. For the investigation, hot-rolled steel I-sections are chosen based on the limiting values of b/t. The edge stiffener is sized up from zero (unstiffened) to a size big enough to make a stiffened edge; then, finite-element analysis is used to analyze it under compressive force. It was observed that when the lip size increases, the flange stiffens, and the interaction of the flange and web also affects the buckling of the cross section. This behavior is contradicted by the inherent assumption made in the current standard, in which the web and flange are considered as individual elements, and the interaction between web and flanges are ignored. Lips with a size ranging from one-third to one-half of the flange’s outstanding width, maintaining the same thickness as the flange, have been found effective in mitigating local buckling. Further, the study also focusses on the analysis of I-shape cross sections under compression for local buckling and gives expression for elastic local buckling coefficient (k), considering interaction between web and flange. A comparative study between the limiting values of w/t ratio provided in the current standard and local buckling values obtained from finite-strip analysis is also presented. Finite-strip analysis results revealed that the actual k-values vary significantly depending on the geometry and stiffness of the section, ranging from 0.06 to 1.51 for flanges and 1.5 to 6.11 for webs. Further, a set of simplified limiting slenderness ratio values are proposed for each combination of web and flange ratios to facilitate the selection of optimum sections that does not buckle locally under compression.
Experimental and Numerical Investigation of Flexural Behaviour of Reinforced Concrete T-Beams Using Digital Image Correlation Vandanapu Ramya Krishna, Hanuma Kasagani, Vinay Kumar Gaddam, Ravi Teja Prathipati, B. Murali Krishna, Shankar Karuppannan Advances in Civil Engineering, 2026 This study investigates the applicability of QR‐code‐based speckle patterns for deformation measurement using two‐dimensional digital image correlation (2D‐DIC) in flexure‐dominated reinforced concrete T‐beam experiments. Three reduced‐scale reinforced concrete T‐beam specimens were tested under monotonic four‐point bending. Surface deformation was recorded using two types of patterns: a conventional random speckle (RS) pattern and a QR‐code‐based structured speckle pattern. Full‐field displacement and strain responses obtained from DIC analysis were used to derive moment–curvature relationships and were compared with reference measurements obtained from conventional instrumentation. Results indicate that the QR‐code pattern provides improved correlation stability and reduced strain‐field noise compared with conventional RS patterns, particularly in regions influenced by crack‐induced deformation gradients. Quantitative comparison showed that deviations in ultimate moment and curvature measurements were lower when QR‐code speckles were used. However, due to the limited number of specimens, the study should be interpreted as a pilot‐scale methodological investigation rather than a statistical validation of pattern superiority. The findings demonstrate the feasibility of using QR‐code‐based patterns to improve subset tracking reliability in laboratory‐scale reinforced concrete experiments and provide a robust methodological framework for future DIC‐based structural investigations.
Self-compacting concrete with fly ash and silica fume: experimental evaluation, microstructural analysis, and machine learning modeling Siva Shanmukha Anjaneya Babu Padavala, Siva Avudaiappan, Yeswanth Paluri, Ch Naga Bharath, Sri Ram Ravi Teja Prathipati, Adamu Mulatu Kumara Scientific Reports, 2025 This study comprehensively evaluates the fresh, mechanical, durability, and microstructural performance of self-compacting concrete (SCC) incorporating fly ash (FA) and silica fume (SF) as supplementary cementitious materials (SCMs). Cement was partially replaced with FA at 20%, 30%, and 40% and SF at 5%, 7.5%, and 10%, forming both binary and ternary combinations. The optimum FA content was established at 30%, beyond which early strength decreased due to dilution effects. Ternary blends with 30% FA + 5–10% SF were further developed to examine synergistic effects. Fresh property tests (slump flow, T₅₀₀, V-funnel, and L-box) confirmed all SCC mixes satisfied EFNARC criteria, with ternary blends exhibiting the best balance between flowability (720 mm slump flow), viscosity (T₅₀₀ = 3.5 s), and passing ability (H₂/H₁ ≥ 0.9). Mechanical performance improved consistently with SCM incorporation; at 180 days, the FA30SF7.5 mix attained 68 MPa compressive strength, 6.3 MPa split tensile, and 8.9 MPa flexural strength, surpassing the control by 17–22%. Durability tests demonstrated marked improvement, sorptivity reduced by 34%, rapid chloride penetration test (RCPT) charge fell from 3600 C (Moderate) to 800 C (Very Low), and ultrasonic pulse velocity (UPV) exceeded 4.75 km/s, confirming a highly dense matrix. Microstructural analysis revealed a compact C–S–H gel network and diminished portlandite content in ternary mixes, evidencing improved hydration and pozzolanic activity. Machine learning (ML) models (KNN, SVM, DT, and RF) successfully predicted compressive strength, with the Random Forest model achieving R 2 of 0.97. The combined experimental–ML approach demonstrates that SCC with 30% FA and 7.5% SF offers optimal performance, coupling sustainability with superior mechanical and durability characteristics.
Sustainable Paving Solutions: Laboratory Analysis of Geopolymer Paver Blocks with Reclaimed Asphalt Pavement Aggregates Yeswanth Paluri, Teja Prathipati S R R, Vijay Kunamineni, Bhavitha Chowdary V, Tottaramudi Pavan Kumar Ssrg International Journal of Civil Engineering, 2025 India's urban infrastructure faces a critical gap in pedestrian and non-motorized transport facilities. While Concrete Paver Blocks (CPBs) are commonly used for this purpose, their production has significant environmental impacts. This investigation examines geopolymer concrete as a viable, sustainable substitute for conventional paver blocks. Geopolymer Paver Blocks (GPBs) are synthesized utilizing fly ash, Ground Granulated Blast furnace Slag (GGBS), and an alkaline activating agent. Reclaimed Asphalt Pavement (RAP) aggregates were integrated to augment sustainability further as a substitute for traditional aggregates. The study evaluated the mechanical, durability, and abrasion properties of the developed GPBs, comparing them to traditional CPBs. Incorporating Reclaimed Asphalt Pavement (RAP) aggregates contributed to a decrease in the workability of freshly mixed concrete. Empirical investigations demonstrated that integrating RAP aggregates led to a deterioration in the mechanical strength characteristics of Geopolymer Binders (GPBs); however, they still adhered to the requirements as per IS 15658: 2021. Notably, GPBs exhibited enhanced durability attributes compared to traditional concrete. Moreover, the research found that the abrasion loss of GPBs was less than that of CPBs, although an increase in RAP content was associated with heightened abrasion loss. The insights gained from this study reinforce the potential of incorporating RAP into GPBs as a significant step toward sustainable infrastructure development, thereby reducing the carbon footprint associated with conventional cement-based materials.
Experimental and analytical investigation of a model towards predicting the compressive stress–strain behavior of Graded Glass Fiber Reinforced Concrete (GGFRC) using fiber reinforcing index Hanuma Kasagani, S. R. R. Teja Prathipati, Srikanth Koniki, C. B. K. Rao Structural Concrete, 2024 The stress–strain behavior of graded glass fiber reinforced concrete (GGFRC) is a crucial factor in its performance and appropriateness for diverse applications. In the present study, experimental and analytical methods were used to develop a model for the stress–strain behavior of GGFRC under uniaxial loading. The experimental program is designed to investigate the impact of mono glass fibers (3, 6, 12, and 20 mm) with varying volume fractions (0.1%–0.5%) and graded glass fibers (combinations of 3 + 6 + 12 + 20 mm) on the behavior of concrete of M50 grade. By grading glass fiber lengths in the concrete, GGFRC's pre‐peak strength and post‐peak deformation have increased, allowing the composite to control the various scales of cracking. A uniaxial compressive stress–strain model has been developed utilizing the fiber reinforcing index to predict the stress–strain curves of GGFRC in compression. The fiber reinforcing index, which is a measure of the quantity of fiber reinforcement in the material, is used as a variable in the current model to observe how it impacts the material's behavior. This would help evaluate the material's behavior under uniaxial compressive loading conditions and then use that data to develop a mathematical model that can predict the material's response under other conditions. Finally, it can be concluded that there is a significant correlation between the experimental results and the proposed analytical model.

An experimental study on the effect of a Viscosity Modifying Agent on the rheological and strength behaviour of 3D Printed Concrete SRR Teja Prathipati, J. Vardhan, D. Murali, C. Nithin, C. Karthik Sai Journal of Physics Conference Series, 2024 Automatic construction technologies have become the primary focus of the global construction sector. 3D printing is one of the disruptive technologies emerging from Industrial Revolution 4.0. 3D printing has grown increasingly popular in concrete construction due to its architectural freedom, speed, formwork-free printing, lesser waste creation, eco-friendliness, affordability, and safety. There were issues with the printing process when manufacturing 3D-Printed Concrete (3DPC) mixes, such as poor extrusion and buildability issues. This study investigates the use of Viscosity Modifying Agents (VMAs) in 3DPC to improve printability as well as structural integrity. VMAs, known for their capacity to change the rheological properties of concrete mixtures, are used selectively to optimise the material’s flow behaviour throughout the 3D printing process. The study compares the effect of VMA concentrations on the workability and buildability properties of 3DPC mixtures. Comparative examinations of VMA-enhanced and traditional 3DPC specimens indicate that an optimised VMA dose improves structural performance. The findings of this study hold significant relevance for the advancement of 3D printing technology in construction, offering a more nuanced understanding of the role of VMAs in optimising concrete mixtures for additive manufacturing.
