Prediction on mechanical properties of engineered cementitious composites: An experimental and machine learning approach N. Shanmugasundaram, S. Praveenkumar Structural Concrete, 2025 The adoption of engineered cementitious composites (ECC) has witnessed a notable surge in recent years, primarily because of their remarkable strain‐hardening behavior and other hardened properties. On the other hand, machine learning (ML) approaches have been widely employed to predict various properties in engineering applications by incorporating an ‘n’ number of inputs and target data. An ML aids in understanding the selection, properties, and blending ability of materials, thereby reducing the cost and duration of research. In this study, an ML technique based on an artificial neural network (ANN) is utilized to predict the mechanical properties of ECC with different binders. For this purpose, several parameters are collected from the present investigation and various literature sources, and the collected data are trained using three algorithms, namely, scaled conjugate gradient (SCG), Bayesian regularization (BR), and Levenberg–Marquardt (LM). The correlations and variations between the experimental and predicted outputs are analyzed. In addition, a comparison between the experimental results obtained by each investigator and the corresponding outputs predicted by the individual algorithms is highlighted. The LM algorithm achieved a mean regression value of 0.910 for the prediction of compressive strength, whereas the BR showed values of 0.908 and 0.852 for predicting the direct tensile and flexural properties of ECC, respectively. Furthermore, considering the standard benchmark, the proposed model exhibited a high correlation with the coefficient of determination (R2).
The interplay among particle packing, binder, and strength: amelioration of ultra-high performance concrete with nanomaterials, a hope or hype? Indhumathi S., Praveen Kumar S., Dinesh A., Moorthi Pichumani European Journal of Environmental and Civil Engineering, 2025 A Middling quality of concrete exacerbates deterioration that tarnishes structural integrity and leads to dilapidated infrastructures. The significant intent of this work is to develop sustainable Ultra-High-Performance Concrete (UHPC) using nanosilica and nano clay. The factors, such as particle size, shape, and particle packing effect plays a key role in development of eco-friendly UHPC. Elkem Materials Mixture Analyser (EMMA), based on Modified Andreasen and Andersen particle packing theory is employed for mix optimization to attain dense packing with low binder content. UHPC is amalgamated with cement, silica fume, nanosilica, and nano clay in various combinations. The mix combination includes control mix (A0), B1–B3 that holds 1–3% nano silica, and C1–C3 yields 1–3% nano clay. It is inferred, B3 (3% nanosilica) exhibits the highest compressive strength of 118 MPa due to its size, quasi spherical shape, and homogenous dispersion. Consequently, C2 (2% nanoclay) manifest 18 and 33% enhancement in splitting tensile and modulus of rupture due to due to layered shape of nano clay that acts as reinforcement, inhibits cracks, and improves strength Microstructural analysis confirms the formation of additional hydration products with less voids. Thus, synergy of particle size, shape, and packing effect results in sustainable UHPC.
Pozzolanic evaluation of Portland cement blended with agro-industrial by-products: An experimental and thermodynamic modeling technique N. Shanmugasundaram, S. Praveenkumar Construction and Building Materials, 2024 This article examines the pozzolanic performance of Portland cement blended with ground granulated blast furnace slag (GGBS), and bagasse Ash (BA). The effect of different water to binder ratios in cementitious composites is analyzed through the hydration process of the proposed mixes using thermodynamic modeling and experimental technique. The hydration of the composites involves the formation of Portlandite , calcium-silicate hydrate (C-S-H), ettringite and monosulfoaluminate (AFm) at 28 days. The results of thermodynamic modeling are compared with compressive strength , dry density, Frattini, lime saturation and strength activity index tests. Portland cement blended with GGBS attained better pozzolanic activity with 0.4 and 0.5 water to binder ratios than admixed BA under all types of testing. The compressive strength of GGBS blended mixes with water to binder ratios of 0.4 and 0.5 attained 51.5 MPa and 44.458 MPa, respectively, at 28 days, which are 20.778% and 12.128% higher compared to BA blended mixes. • Pozzolanic performance of SCMs using thermodynamic model (CemGEM’s). • Hydration of Portland cement blended with SCMs. • Effect of water-to-binders ratios and SCMs on hydration of Portland cement. • Pozzolanic performance of SCMs using SAI and lime saturation test methods. • Compressive strength of cement mortar with GGBS and bagasse ash.
