Abstract |
A series of experiments were conducted to examine the variation in hydraulic conductivity within and among three matrices formed by steel mill baghouse dust treated with 8%, 9%, and 10% Normal Portland Cement. Commercially available equipment was modified to allow sensitive and continuous monitoring of hydraulic conductivity. Examination of samples by scanning electron microscopy and energy dispersive x-ray indicated the formation of ettringite in the solidified waste pores, thus reducing the hydraulic conductivity by two orders of magnitude. Gradient was the most significant parameter affecting variation within each matrix. Temporal effects and cement content were identified as important factors affecting hydraulic conductivity measurements and should be considered by regulatory tests. |
