Abstract: |
As the repair time of pavement is highly required, the curing time of epoxy resin concrete under the condition of self made microwave radiation equipment is tested. The results show the epoxy resin concrete can be cured in 10 minutes. The mechanical properties of cured resin concrete were studied and the results show that resin concrete cured by microwave has compressive strength of 50 MPa, flexural strength of above 10 MPa, and good low temperature deformation ability. The developed epoxy resin concrete has a lot of advantages, such as rapid hardening, high strength, convenient construction, which is suitable for rapid road repairing and constructing engineering. |
