PURPOSE:To facilitate the sampling without separating a reinforcing steel, by a method wherein a mold is formed in the perimeter of an exposed corroded reinforcing steel from a matrix material and the mold is filled with a plasticizer by injection to obtain a simulation sample. CONSTITUTION:Concrete 1 is removed at an oxidation corroded part of a reinforcing steel to expose a buried reinforcing steel 2 and after a releasing agent is applied in the perimeter of the reinforcing steel 2, a mold form 4 is put over the steel through a spacer 5. Moreover, a matrix material 3 composed of a rapid-curing plastic material is injected into a clearance between the mold form 4 and the reinforcing steel 2 to solidify; then, the matrix material 3 is taken out. The matrix material 3 taken out is restored and plastic synthetic resin liquid is injected thereinto as mold to solidify, thereby making a simulation sample. Then, the simulation sample undergoes strength test.
