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.

An evaluation of the concrete strength has very important meaning in the maintenance and the structural safety. The reliability of ferroconcrete building is weakening and enlarging the life is strongly demanded due to the early deterioration of concrete. Like this social demand, concrete strength presumption is being indirectly executed using the result in parallel with the concrete pouring by material age. This data is usually different as concrete poured practically and the way of hardening and curing. Although existing concrete strength presumption formula is proposed, the material used and the concrete strength is different. And as a matter of remicon, the concrete strength varies according to the site and the way of curing. So the objective of this research is strength evaluation of the structural body concrete according to the concrete pouring and curing temperature change seasonally after using the system which evaluates the structural body concrete strength which is applied the transparent junction-separation mold that is presented. Also there is an objective to present the fundamental data for the constructional quality technique proposal of the structural body concrete developed in relation to field specimen and the strength evaluation method by non-breaking.

In order to verify the strength of slurry shotcrete compared to existing shotcrete, The results were analyzed and evaluated.

It will use the Schmidt hammer law, the Ultrasonic waves velocity law and the composition law in the concrete Korean mandolin lump examination law from the research which it sees consequently and proposal of the usual concrete and existing regarding the high-in-tensity concrete the comparison which will be cool it will analyze and compared to accurately the burglar presumption which is the possibility of buying the compressive strength of the concrete it will be cool and it proposes.
