    Experimental studies on Iron-ore tailing based interlocking paver blocks
    (2012) Ravi Kumar, C.M.; Anil, A.; Prashanth, M.H.; Venkat Reddy, D.
    Interlocking concrete block pavers (ICBP) has been extensively used in many of the countries due to concern with durability. They are utilized in a variety of commercial, municipal and industrial applications. The superior engineering properties, low maintenance, ease of placement and removal, aesthetic appeal and immediate availability are the primary reasons for choosing concrete block pavement over other paving surfaces. ICBP are colored using iron oxide pigments. The present investigation details the properties of ICBPs mixed with iron ore tailings as a partial replacement for cement. The paper discusses the experimental studies on strength characteristics and water absorption of iron ore tailings based concrete paver blocks by considering actual area and plan area and results has been compared with that of conventional concrete paver blocks. © 2012 Cafet-innova technical society. © 2012 Cafet-Innova Technical Society.

    An investigation of slurry erosion behaviour in plasma-sprayed carbon nanotube-reinforced fly ash/alumina coatings using experimental analysis and artificial neural computing for marine and offshore applications
    (Elsevier Ltd, 2024) Chavana, N.; Anil, A.; Jambagi, S.C.
    This study investigates carbon nanotube (CNT)-reinforced alumina fly ash (FA) coatings, namely AF (unreinforced), 1CAF (with 1 wt% CNT), and 2CAF (with 2 wt% CNT), on marine-grade steel. Microstructural analysis shows 1CAF coatings denser by ∼15.32% due to CNT reinforcement, while 2CAF coatings display ∼9.68% increased porosity from CNT agglomeration. Raman spectroscopy confirms CNT retention. 1CAF coatings exhibit ∼14.66% higher microhardness, ∼15.96% higher adhesion strength, and ∼15.66% improved fracture toughness compared to AF coatings, attributed to pore sealing through CNT reinforcement. Enhanced erosion resistance (∼14.59%) in 1CAF coatings was observed due to improved mechanical properties and CNTs mitigating crack propagation. Validation through an artificial neural network (ANN) modeling and regression analysis supports 1CAF coatings’ promise for harsh marine environments, offering enhanced durability. © 2024 Elsevier Ltd
