ABSTRACT
The application of Xypex results in a rapid reduction in DC1 within 6 weeks (Table 3) to a value below that of the CW control samples. The reduction is more pronounced in the surface layer than at depth. However, in contrast to DP, the XF,U series do not apparently show a long term reduction in DC1. Indeed following treatment the CW, XF and U series show quite similar values of DC1.
