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.
