An anticorrosive nanocomposite is described. The anticorrosive nanocomposite includes a cured epoxy and jute carbon. The jute carbon is in the form of flakes. The flakes have a particle size of 0.05-15 micrometers (μm). Particles of the jute carbon are dispersed in the cured epoxy. A method of preparing the jute carbon is also described.

Anticorrosive nanocomposite

A cement composition includes a curable component in an amount of 10 to 25 wt. %; a fine aggregate (FA) in an amount of 20 to 40 wt. %; a coarse aggregate (CA) in an amount of 40 to 50 wt. %; and an alkaline component in an amount of 5 to 15 wt. %, each wt. % based on the total weight of the cement composition. The curable component includes a cementitious material having an average particle size (D) of 10 to 17 micrometers (μm), a limestone powder (LSP) material having a Dof 13 to 19 μm, a red mud (RM) material having a Dof 30 to 36 μm, a silicomanganese fume (SMF) material having a Dof 28 to 34 μm, and a natural pozzolan (NP) material having a Dof 13 to 19 μm.

Alkali-activated cement composition

A method for producing a submicron-/nano-jute carbon/epoxy composite anti-corrosion coating is described. The method includes heating a jute stick, grinding the jute stick to form a first powder; pyrolyzing the first powder to form a pyrolyzed carbon; grinding the pyrolyzed carbon to form a second powder; ball milling the second powder under the wet conditions to form a submicron-/nano-jutecarbon; mixing the submicron-/nano-jutecarbon, and an epoxy resin to form a first mixture; mixing a hardener with the first mixture to form a second mixture, and coating the second mixture on a mild steel substrate and curing to form the submicron-/nano-jutecarbon/epoxy composite anti-corrosion coating.

Method for producing anti-corrosion composite coating

A method of producing submicron carbon particles from oil ash. The method comprises pyrolyzing the oil ash to produce a pyrolyzed oil ash and milling the pyrolyzed oil ash to produce carbon particles having a mean particle size in the submicron regime. The method produces submicron carbon particles which have a very high carbon content (90 to 99 atom %) and a very low content of oxygen, the particles having a ratio of carbon to oxygen ratio of 10:1 to 99:1. The size of the particles may be controlled by the duration of the milling. The submicron carbon particles are devoid of functionalities containing carbon-oxygen double bonds as measured by Raman spectroscopy and X-ray photoelectron spectroscopy (XPS).
