초록

Existing non-destructive test for evaluation of concrete compressive strength may show deviation in results analysis due to
deterioration of precision by strength calibration and dry or humid condition by age, so there needs be testing method to
determine long term structural internal force by collecting specimen with no damage of structure and measuring compressive
strength through destruction test.
This research applied to mock-up member the compressive strength evaluation method using joint separation mold that can
plan and produce specimen cured in the same composition environment as concrete structure by attaching arbitrary(joint
separation) to the form before concrete piling, and as a result, the management specimen was contrary to the hydration
temperature of the member or was affected by external atmospheric temperature, however the joint separation specimen
connected to structure and managed in the same environment showed a temperature curve similar to the member and decrease
in temperature difference.
Additionally, from initial age, with the compressive strength of joint separation specimen most similar to core strength, stable
compressive strength can be evaluated up to design criteria strength 100MPa, so the method is proposed as an evaluation
technique that can confirm highly reliable concrete quality.
