Review of Nitrite Inhibitor for Protection of Rebar Corrosion
Abstract: Load bearing concrete structures need steel reinforcement (rebar) strips or rods, which are prone to attack by the corrosive environment inside the concrete due to constant ingress of moisture, pollutant gases and anions (mainly Cl-, SO4- -). One of the means of reducing such type of corrosion is the use of inhibitors. Inhibitors are water soluble but film forming on metals by their selective adsorption on the metal surface. These …

Monitoring the Effectiveness of Water-Based Plants for the Inhibition of Metal
Abstract: The temperature performance profile of the plant extracts shows that inhibition efficiency increased with increasing temperature of the system until at about 323K at 9.00hrs immersion time where a decline in inhibition efficiency occurred implying the opposite at higher temperatures and longer immersion time. Corrosion rate parameters changed with rise in temperature and exposure – immersion time. Plots of rates of corrosion against the volume(s) of the test inhibitor(s) in …

Synergistic Effects of Hybridized Nano-Silica and Hemp Fiber Reinforcement on Bio-Epoxy Composites
Abstract: Natural fiber-reinforced bio-epoxy composites have become promising sustainable alternatives to conventional synthetic-fiber petroleum-based materials, but are often limited by low fiber-matrix interfacial bonding, low thermal stability, and high moisture absorption which limit their application in structural applications. These issues are discussed in this work, by carrying out a systematic investigation of the synergistic effects of the hybridization of nano-silica particles with alkali-treated hemp fibers in a bio-epoxy matrix the composites …
