  • Assessment of thermally induced strength loss in alkali-activated concrete through ensemble regression models
    Yellanki Deepti, Sanjay Kumar, Atrayee Bandyopadhyay, Pramod Kumar, Regasa Yadeta Sembeta
    Scientific Reports, 2026
    Alkali-activated concrete (AAC) is a sustainable alternative to Portland cement, offering superior thermal resistance. However, predicting the residual compressive strength of AAC after high-temperature exposure remains a complex challenge. This study addresses this gap by using machine learning (ML) to model AAC performance. A comprehensive database of 371 samples was compiled from the experimental analysis, detailing mix proportions and residual compressive strength after exposure to temperatures from 30 °C to 1000 °C. Five supervised machine learning models (Decision Tree, Bagging Regressor, AdaBoost, Random Forest, and XGBoost) were developed and evaluated. The XG Boost (XGB) model demonstrated the highest predictive accuracy, achieving a coefficient of determination (R²) of 0.95 and the lowest root mean square error (RMSE) of 2.50. A feature correlation analysis identified curing temperature, curing duration, and alkali activator concentration as the most influential parameters. This study provides a validated ML model for accurately predicting the residual strength of AAC, offering a reliable tool for designing fire-resistant, sustainable concrete mixtures.
  • Synergic utilization of waste glass powder for fire-resilient and low alkali-activated concrete

    Scientific Reports, 2026
    Ordinary Portland Cement (OPC) concrete suffers severe degradation at high temperatures, and its production carries a significant carbon footprint, necessitating sustainable, fire-resilient alternatives. This study evaluates an Alkali-Activated Concrete (AAC) system based on Fly Ash (FA) and Ground Granulated Blast Furnace Slag (GGBFS), where Waste Glass Powder (WGP) was systematically investigated as a precursor replacement. Key variables included a 25% WGP replacement for FA or GGBFS and varied NaOH concentrations (8–10%). Specimens were tested for residual mechanical performance (compressive strength, stress-strain, ductility, energy absorption) after exposure to temperatures up to 1000 °C. Crucially, replacing 25% of fly ash with WGP (Mix M3C5) yielded the highest ambient compressive strength (68.61 MPa) with a reduced alkali demand of only 8% NaOH. This significantly surpassed the baseline FA-GGBFS control mix (M1Na10), which required 10% NaOH to achieve a lower peak strength of 53.16 MPa. Furthermore, the optimized WGP formulation (M3C5) demonstrated excellent thermo-mechanical stability, retaining 40.3% of its strength (27.66 MPa) at 1000 °C. This represents a superior residual load-bearing capacity compared to the baseline M1Na10 mix (24.25 MPa) and exhibited superior ductility compared to the baseline mixes at extreme temperatures. Microstructural analyses (XRD, SEM, EDS) confirmed that WGP promoted a denser, more homogeneous, silica-rich gel matrix, which mitigated thermal microcracking and explained the enhanced performance. This work establishes WGP as a synergistic precursor in AAC, enabling the production of high-performance, fire-resilient concrete with reduced alkali requirements. This strategy effectively valorizes waste glass, contributes to a lower-carbon built environment and supports the principles of a circular economy.

  • Microbial repairing of concrete & its role in CO2 sequestration: a critical review

    Background Being the most widely used construction material, concrete health is considered a very important aspect from the structural point of view. Microcracks in concrete cause water and chlorine ions to enter the structure, causing the concrete to degrade and the reinforcement to corrode, posing an unacceptable level of structural risk. Hence repair of these cracks in an eco-friendly and cost-effective way is in the interest of various researchers. Microbially induced calcite precipitation (MICP) is an effective way considered by various researchers to heal those concrete cracks along with an important environmental contribution of CO2 (carbon dioxide) sequestration in the process. Main content As the current concentration of CO2 in the earth’s atmosphere is about 412 ppm, it possesses a deadly threat to the environmental issue of global warming. The use of bacteria for MICP can not only be a viable solution to repairing concrete cracks but also can play an important role of CO2 arrestation in carbonate form. This will help in carbon level management to lessen the adverse effects of this greenhouse gas on the atmospheric environment, particularly on the climate. To overcome the insufficiency of studies concentrating on this aspect, this review article focuses on the metabolic pathways and mechanisms of MICP and highlights the value of MICP for CO2 arrestation/sequestration from the atmosphere during the process of self-healing of concrete cracks, which is also the novelty of this work. An overview of recent studies on the implementation of MICP in concrete crack repair is used to discuss and analyse the factors influencing the effectiveness of MICP in the process, including various approaches used for CO2 sequestration. Furthermore, this investigation concentrates on finding the scope of work in the same field for the most effective ways of CO2 sequestration in the process of self-healing cracks of concrete. Conclusion In a prospective study, MICP can be an effective technology for CO2 sequestration in concrete crack repair, as it can reduce adverse environmental impacts and provide greener environment. This critical study concludes that MICP can bear a significant role in arrestation/sequestration of CO2, under proper atmospheric conditions with a cautious selection of microorganisms and its nutrient for the MICP procedure.
