Evaluation of Sulfuric Acid Resistant Mortar as a Corrosion Protection Method for Sewerage Facilities

Evaluation of Corrosion Caused by Biogenic Sulfuric Acid (BSA) on the Concrete Structures of Sewerage Systems (Chemical Tests)

Acid Resistance of Fly ash based Geopolymer mortars

Geopolymers are a new promising binder manufactured by activation of a solid aluminosilicate source material with a highly alkaline activating solution and aided by heat. Fly ash, considered to be a waste material is rich in silica and alumina and hence can be used as a source material for manufacture of Geopolymers. These binders have been reported to achieve high early strength and better dur...

EIS capacitance diagnosis of nanoporosity effect on the corrosion protection of DLC films

An electrochemical impedance spectroscopy (EIS) capacitance diagnostic method was developed to measure the nanoporosity in DC magnetron-sputtered diamond-like carbon (DLC) films deposited on highly conductive silicon (111) substrates. The measurement was based on a calibration of artificial defects enclosed in a well-defined area. Films of known nanoporosity, as determined by EIS, were used to ...

Silica sulfuric acid mediated protection of carbonyl groups as 2,4- dinitrophenylhydrazone

Silica sulfuric acid is employed as solid acid catalyst for the clean and less hazardousprotection of carbonyl compounds as 2,4-dinitrophenylhydrazone under solvent-free conditions.

Prevention of stack corrosion under wet flue gas desulfurization conditions in a coal-fired power plant: performance analysis and comparative study

Background: This study investigated the prevention of stack corrosion under wet flue gas desulfurization conditions in a coal-fired power plant. The performance analysis and comparative studies of six materials for the prevention of stack corrosion were investigated. Results: The ion chromatography analysis showed the acid condensation contained fluoride, chloride, nitrate, sulphate, and sulphi...
