  • Bioconvection Flow in the Existence of MHD Carreau Nanofluid With Cattaneo–Christov Model
    M. Vinodkumar Reddy, Tusar Kanti Das, K. Malleswari, A. Narender Reddy, Jintu Mani Nath
    Chemical Engineering and Technology, 2026
    This study explores the analysis of the magnetohydrodynamic stagnation point flow of the Cattaneo–Christov thermal flux model of Carreau nanofluid over a stretched sheet incorporating gyrotactic microorganisms and Joule heating. Moreover, integrating the influences of activation energy, chemical reactions, heat source, Brownian motion, and thermophoresis provides the distinctiveness of this investigation. Numerical outcomes are attained using a Runge–Kutta‐based shooting technique implemented via the MATLAB BVP5C approach. The influences of several dimensionless parameters on velocity, thermal, and concentration profiles are represented graphically. Notable findings indicate that the thermal distribution is enhanced for augmenting the heat source and thermal radiation.

    The utilization of composite materials as alternatives to Ordinary Portland Cement (OPC) is essential in mitigating the environmental impact of cement production. This study investigates the potential of industrial by-products rich in silica and alumina, such as fly ash (FA), alccofine (ALC), and nano silica (CNS), to partially replace OPC in concrete. Tetranary blended nano concrete (TBNC) compositions, incorporating 25% FA, 10% ALC, and varying proportions of CNS (0%, 0.5%, 1%, 2%, and 3%), were examined for their compressive strength in M30 and M60 grade concrete following a 90-day curing period. Results demonstrate the significant influence of CNS on compressive strength of TBNC. To validate these findings, Response Surface Methodology (RSM) was employed for mathematical modeling and statistical analysis, predicting compressive strength values and comparing them with experimental data. This research underscores the viability of utilizing industrial by-products in concrete production, thereby promoting sustainable construction practices

    This research aimed to evaluate the influence of alccofine 1203 on a mineral admixture and sodium nitrite as a corrosion inhibitor on the properties of concrete. To achieve these aims, an experimental investigation was carried out on a set of composite samples comprising five distinct concrete formulations. Five different mixes for the concrete were used as the overlay materials such as NC as a reference concrete, alccofine concrete (i.e. 25% cement replaced with alccofine), and alccofine concrete with varying dosages of sodium nitrite (i.e. 1%, 1.25%, and 1.5%). Alccofine reduced the workability and water absorption and increased the compressive strength of the concrete (5%) at curing age of 28 days. Adding sodium nitrite further reduced water absorption of the concrete and workability but compressive strength of 29.15% and 26.93% for the curing period of 3 and 7 days, respectively. The pH of the concrete powdered solution became more alkaline with the replacement of alccofine and addition of sodium nitrite. Free chloride content dropped by 48 and 66%, respectively, with the introduction of GGBS and sodium nitrite. Corrosion properties of the concrete samples were examined using open circuit potentials and linear polarization resistance of various concrete mixes after being immersed in 1 M H2SO4 and 3% NaCl environment. The findings indicated a notable improvement in the corrosion resistance, water absorption test, thermal conductivity, strength properties, and microstructural properties of concrete with the incorporation of SN in combination with alccofine. The application of the response surface method allowed for the prediction, validation, and optimization of experimental data using a regression equation.
  • Strength prediction of modified self-compacting concrete using response surface method

    This study highlights the effectiveness of the response surface method in predicting the properties of hardened concrete containing spent foundry sand and manufactured-sand. In current research, different mix proportions are prepared with spent foundry sand and manufactured-sand as partial replacements for fine aggregate. The workability, strength, and durability studies are conducted on all concrete mixes. The test results confirm that the inclusion of 20% of spent foundry sand is optimum for enhancing the strength and durability. Also, the inclusion of 20% of spent foundry sand in manufactured-sand concrete also possesses optimum results in strength and durability. Further, the response surface method has been employed to develop a model for compressive strength prediction. The R-squared and residual sum of squares of error for the compressive strength model were 0.9863 and 2.345, which confirms the goodness of the fit.
  • Acid resistance of ternary blended nanosilica concrete incorporating fly ash and alccofine
    Avuthu Narender Reddy, T. Meena
    Civil Engineering and Architecture, 2021
    The use of industrial waste or byproducts as a replacement of cement leads to cost reduction, energy-saving, and is also eco-friendly. Studies reveal that the quaternary and ternary blended concrete may be superior in durability properties when compared with conventional concrete. With the expansion of the use of concrete structures in the sewage system, the corrosion effects of aggressive acid attacks on cement-based construction have gained more significance. The present study aims to investigate the acid resistance of M30 and M60 grades of concrete and the influence of the combination of fly ash, alccofine, and nanosilica in it. The combination of 25% fly ash, 10% alccofine and various percentages of nanosilica (0.5%, 1%, 2%, 3%) have been tested for 28, 56, 90,180 days for acid resistance. From the result, it is seen that the concrete with a combination of fly ash, alccofine, and nanosilica showed better performance in resisting the acid attack on M30 and M60 grades of concrete based on percentage weight loss of specimens over different curing periods.
  • Influence of nanomaterial on high-volume fly ash concrete: a statistical approach

    Innovative Infrastructure Solutions, 2020
    This work is focused on the mechanical properties of ternary blended nanoconcrete replacing cement with fly ash and nanosilica in the optimized percentage. Ternary blended nanoconcrete mix is designed with 0.45 water-to-binder ratio and 438 kg/m3 of cementitious content in all mixtures with a combination of various percentages of nanosilica and 40% of fly ash by weight of cement. The mechanical properties like compressive, split tensile and flexural strength tests at the age of 7, 14 and 28 days are performed. With the addition of nanosilica, the enhancement was observed in all mechanical properties, but when the dosage of nanosilica was more than optimum, bleeding as well as segregation in concrete was observed. Response surface method was used in predicting the values of compressive strength in this work, which was found to be in agreement with the experimental observations with at least 95% confidence levels.
  • Strength enhancement of concrete incorporating alccofine and SNF based admixture
    P. Reddy, Bharat Bhushan Jindal, B. V. Kavyateja, Avuthu Narender Reddy
    Advances in Concrete Construction, 2020
    Cement is the most significant component in concrete. Large scale manufacturing of cement consumes more energy and release harmful products (Carbon dioxide) into the atmosphere that adversely affect the environment and depletes the natural resources. A lot of research is going on in globally concentrating on the recycling and reuse of waste materials from many industries. A major share of research is focused on finding cementitious materials alternatives to ordinary Portland cement. Many industrial waste by-products such as quartz powder, metakaolin, ground granulated blast furnace slag, silica fume, and fly ash etc. are under investigations for replacement of cement in concrete to minimize greenhouse gases and improve the sustainable construction. In current research, the effects of a new generation, ultra-fine material i.e., alccofine which is obtained from ground granulated blast furnace slag are studied as partial replacement by 25% and with varying amounts of sulfonated naphthalene formaldehyde (i.e., 0.3%, 0.35% and 0.40%) on mechanical, water absorption, thermal and microstructural properties of concrete. The results showed moderate improvement in all concrete properties. Addition of SNF with combination of alccofine showed a significant enhancement in fresh, hardened properties and water absorption test as well as thermal and microstructural properties of concrete.
