Abstract

The invention discloses an evaluation method for the effect of concrete for preventing pollution of band-discharge waste liquid. The evaluation method comprises a concrete antifouling effect test method based on a gas permeation method, an ion permeation method and a non-radioactive isotope diffusion depth method. The evaluation method integrates various influence factors and can evaluate the effect of preventing the concrete from being polluted by the waste liquid.

Description

technical field [0001] The invention belongs to the field of concrete for nuclear power, in particular to the field of concrete for preventing radioactive waste liquid pollution. Background technique [0002] Concrete in nuclear power plants may be contaminated by radioactive waste due to the particularity of the working environment. The intrusion of the anti-waste liquid on the concrete surface directly affects the determination of the amount of concrete waste and the difficulty of decontamination during the decommissioning process. In order to prevent or minimize the intrusion of waste liquid into concrete, antifouling agents or other protective materials are often applied to the concrete surface. However, there is still no reasonable, scientific and systematic evaluation method for how to evaluate the effect of concrete on preventing pollution with waste liquid. [0003] Cement-based closed-cell and coating-type concrete surface antifouling materials are used to evaluat...
