A Fundamental Study on the Workability Improvement and Strength Properties of Superplasticized Concrete(II) (Part 2, In the Case of Strength Properties of Hardened Concrete)

유동화 콘크리트의 시공성 향상 및 강도특성에 관한 기초적 연구(II) (제2보, 경화콘크리트의 강도 특성을 중심으로)

The effect of superplasticizing agents on the mechanical properties in hardened concrete have been analyzed and investigated under various mix proportions of water cement ratio of 0.40, 0.50, 0.60 and 0.70, Superplasticizing agents of NL-4000, and Rheobuild-716, and addition rate of sp. agents of 0.0, 0.5, 1.0, 1.5 and 2.0 in the practical range. It is the aim of this study to provide the fundamental data on the compressive strength, dynamic and static modulus of elasticity, stress and strain curve of hardened concrete comparing with base concrete and conventional concrete for the practical use and research data accumulation of superplasticized concrete in the side of development of concrete construction technology and management.
