Investigating Prospects of Phyllanthus Muellerianus as Eco-friendly/Sustainable Material for Reducing Concrete Steel-reinforcement Corrosion in Industrial/Microbial Environment

Effects of Phyllanthus muellerianus Leaf-Extract on Steel-Reinforcement Corrosion in 3.5% NaCl-Immersed Concrete

“…For this, the spectrum obtained from the Fourier Transform Infrared (FT-IR) spectroscopy instrument, the Perkin-Elmer ® FT-IR System (Spectrum BX, Waltman, MA, USA), application to the P. muellerianus leaf-extract is presented in Figure 6. As had been previously detailed, the functional classes of adsorbed vibrations, for the identified frequencies in the P. muellerianus leaf-extract FT-IR spectrum (Figure 6), had been reported, along As had been previously detailed, the functional classes of adsorbed vibrations, for the identified frequencies in the P. muellerianus leaf-extract FT-IR spectrum (Figure 6), had been reported, along with the phytochemical characterization, by [33]. However, the rendering of this FT-IR spectrum to the Euclidean Search of the Fluka library, by the Perkin-Elmer ® instrument [72], suggested hit list of 10 organic compounds that are presented, in this study, as 3-D optimized structures of the compounds in Figure 7.…”

“…These considerations, therefore, also garner further support for the usage of the N-, S-, and O-containing and π-electron rich P. muellerianus leaf-extract as an environmentally-friendly inhibitor of steel-reinforcement corrosion in concrete designed for the saline/marine environment. with the phytochemical characterization, by [33].

“…Steel-reinforced concrete slabs for the study were cast in duplicates of size 100 mm × 100 mm × 200 mm that contained similar concentrations of P. muellerianus leaf-extract admixture, and which had been obtained following details from studies [33,36]. Six variations of the P. muellerianus leaf-extract were employed as admixtures in the duplicated design of steel-reinforced concrete specimens for the saline/marine test-environment.…”

“…Baker5. [62,64]. Each of the cast concrete types was of size 100 mm × 100 mm × 200 mm into which 150 mm of reinforcing-steel sample was centrally embedded during the concrete block casting [64].…”

“…[62,64]. Each of the cast concrete types was of size 100 mm × 100 mm × 200 mm into which 150 mm of reinforcing-steel sample was centrally embedded during the concrete block casting [64]. The protrusion of 40 mm remaining on the reinforcing-steel serves for electrochemical test-measurement connection and this was painted with glossy paint immediately after concrete casting.…”
