摘要：

Cement-based materials will release radon which is a carcinogen and affects indoor air quality. This paper summarizes the research situation of radon source control of cement-based materials, and recommends the plugging of radon migration channel. Considering the adverse effects of self-shrinkage cracking during hydration process and the pore structure evolution of cement, this paper considers that the delayed polymerization plugging strategy is feasible for radon pollution control. The mechanism of radon migration in porous media, the improvement of the pore structure of cement-based materials by polymers, and the application of capsule technology in cement-based materials are described in detail.
