بتن اصلاحشده با پلیمر
To complicate and confuse the issue, some advocate rebuilding foundations withpolymer modified con- crete (PMC) products as a way to save money by avoiding those deep epoxy grout pours.
Listing the sequence of events in grouting a piece of machinery using a PMC and epoxy grout will show that an additional day of chipping the concrete and getting ready to make the final pour of an epoxy grout on the PMC will add several additional days to the job before the equipment can be set.
