An Experimental Study on the Compressive Strength Deviation of Concrete With Different Consolidation Methods

다짐 방법에 따른 콘크리트 압축강도 편차에 관한 실험적 연구

This paper presents a basic study which is to develop concrete cylinder moulds for a proficiency testing compressive strength of concrete among laboratories accredited Korea Laboratory Accreditation Scheme(KOLAS). The concrete cylinder moulds sufficiently have homogeneity for a proficiency testing which is a means of assessing the ability of laboratories to competently perform specific test and measurements. The concrete compressive strength specimens placed different consolidation methods were analyzed by a statistic technique. The methods of consolidation are rodding, and internal or external vibration.
