The utility of that publication can be appreciated when it is realized that 13 printings were necessary to supply the great number of persons interested in the subject. This book was originally issued as the Basic Corrosion Course in 1970. The study concluded that organic inhibitors were effective in inhibiting corrosion in cyanide and chloride contaminated concrete cubes.Preface to the First Edition (1984). The inhibition efficiencies for toluene in cassava fluid and seawater were 21.64% and 45.78% respectively. The inhibition efficiencies for different inhibitors followed different trends in different environment. The inhibition levels for the admixed samples in seawater were on the higher side compared with those in cassava fluid. The results obtained showed that all the samples except the control samples, displayed some degree of inhibition. The pH of each medium was also measured throughout the period of exposure. Two controls and admixed samples were later immersed in seawater and cassava fluid, respectively, for durations of thirty-two days to determine the corrosion potentials using a voltmeter and a Copper-Copper Sulphate Electrode (Cu/CuSO4). It was later immersed in seawater and cassava fluid for a total duration of 32 days and the measurements were taken at interval of 4 days in order to determine the corrosion rates in mils per year (mmpy). Eight of the samples were used as control while other eight samples were admixed with dioctylphthalate and toluene in concrete cubes. Forty coupons were used for gravimetry and the remaining five for corrosion potentials measurements. ![]() Gravimetric and voltametric techniques were employed in this study and a total of forty-five corrosion coupons of different dimensions were produced. Hence this study presents the effect of toluene and dioctylphthalate on the rebar corrosion of medium carbon steel in seawater and cassava fluid with a view to determining inhibitive potentials of the different inhibitors in the two media.
