Abstract:Sealing of the concrete specimen is the key to the impermeability test of concrete. For the poor penetration effect problem in the impermeability test of concrete, the sealing mold method of sealing material was studied. The demoulding and sealing effects on epoxy resin mortars with different curing cement ratios under the room temperature were experimented and analyzed by compared with the traditional sealing material of paraffin wax. From the test, it is found that the using epoxy resin mortar as sealing material is convenient, feasible and experimental results are stable. And it effectively protects the experiment from leak at the verge due to sealing material reason and from affecting the judgment of the impermeability function of concrete, which greatly improves the success rate of impermeability experiment.
