The Physical Durability and Electrical Resistivity of Indiana Bottom Ash

“…This figure suggests that corrosion on ferrous pipes occurs initially at a high rate and then continues with a decreasing rate. Romanoff [39] presented a power-law equation to describe the time-dependent corrosion as follows:…”

“…At the turn of the century, all corrosion was attributed to stray current from rail traction systems trolley cars and subways (Romanoff,[39] Figure 19 shows an example of stray dc current from an electric street railway system in which steel rails are used for current return to the generating station.…”

“…Romanoff [39] described an approximate relationship between soil resistivity and its corrosiveness, as shown in Figure 24. This figure displays much scatter but indicates a decrease in metal loss with increasing resistivity.…”

“…Methods for determination of total acidity have been described by Romanoff [39]. The technique in determination of the total acidity was so laborious that its application to corrosivity prediction has been limited (Iverson,[47]).…”

“…This value is the maximum acceptable value for a waste form diffusion cuefficient whaus, 199 11. A compilation of diffusion coefficients for solidified waste forms is presented in [Sullivan and Suen, 19891. For metallic waste forms (activated metals) and glass waste forms surface degradation processes often control Estimates for metallic corrosion rates can be obtained by examining the soil corrosion data [Romanoff, 1957;Gerhold et al, 19811. A discussion of this data and its applicability to modeling waste form release is in [Sullivan and Suen, 19891.…”
