Method for reducing radon radiation by concrete structure crack

摘要

The present invention relates to a radon shielding method for cracks in a concrete structure, and more particularly, to a crack portion generated in a concrete structure, comprising: a first step of filling a foamable adhesive containing aluminum particles; a second step of filling the cracks filled with the foamable adhesive containing aluminum particles in the first step with a concrete adhesive containing a curing agent and aluminum particles; And by including the 3 step of adhering the crack prevention tape on the concrete structure with the crack occurrence point filled with the two-step concrete adhesive between them, durability for long-term use and cracks inside while exhibiting a radon shielding rate of 85% or more It relates to a radon shielding method for cracks in concrete structures that can improve the fluidity of the filler to be filled or the vulnerability to expansion and contraction action.
