슈미트 햄머법 비파괴 시험에 의한 현무암 골재를 사용한 콘크리트의 강도 평가 = Evaluation of Compressive Strength of Concrete Using Basalt with Schmidt Hammer Method

다국어 초록 (Multilingual Abstract)

This paper is intended to provide the reference data on the standardization of nondestructive test of concrete using basalt aggregate produced in Cheju island. Compressive strength and rebound number of schmidt hammer are measured. Concrete using granite stone are also tested. According to experimental results, compressive strength of concrete using basalt aggregate is highly estimated compared to that using granite stone about 10~20% for same rebound number condition. It is urgently necessary to prescribe modified evaluation formular of compressive strength with schmidt hammer considering our condition because existing estimation formular provided in Japan underestimate the compressive strength of concrete using basalt aggregate.
