Grouting of Contaminated Soils

The effectiveness of grouting a contaminated soil depends in large part on both the contaminant-grout and the contaminant-soil interactions. These phenomenon are being investigated for a system wherein a microfine cement grout is injected into three different gasoline-contaminated soils. Experiments conducted to determine the bleed capacity and microstructure of neat grouts containing various percentages of gasoline have revealed: (a) the presence of a small amount of gasoline significantly reduces the bleed capacity of the grout, and (b) discrete entities of gasoline were encapsulated within the grout microstructure.
