Concrete Repair by epoxy mortar

The epoxy is a two-component organic polymer. Epoxy mortars and concrete are a blend of epoxy and sand or epoxy and sand plus coarse aggregate. The epoxy system with or without aggregate will provide an impermeable environment and barrier that will protect the reinforcing steel against corrosion. The epoxy mortar/concrete has little or no shrinkage. During the curing process the exothermic reaction will create a temperature rise that will cause the mass to expand. The presence of fine and coarse aggregate will minimize the temperature rise and subsequent expansion. As the mass cools, there will be shrinkage that will return the mass to its original size. In short, the mass will expand during the exothermic reaction and contract during the cooling period.
