초록

본 연구에서는 붕규산 유리와 비정질 붕소강 섬유를 혼입한 콘크리트의 역학적 성능 및 중성자 차폐성능을 평가하였다. 잔골재를 붕규산 유리로 치환한 콘크리트와 비정질 붕소강 섬유를 보강한 콘크리트를 제조하여 압축강도, 정탄성계수, 압축인성, 휨강도, 휨인성, 중성자 차폐성능을 평가하였다. 실험결과, Plain 콘크리트와 대비하여 붕규산 유리를 혼입한 콘크리트의 경우 압축강도 및 휨강도는 저하되었으나, 중성자 차폐성능은 향상되는 것으로 나타났다. 비정질 붕소강 섬유를 혼입한 콘크리트의 경우 Plain 콘크리트와 대비하여 압축인성 및 휨인성이 증진되었으며 중성자 차폐성능도 향상되는 것으로 나타났다.

In this study, the mechanical properties and the neutron shielding rate of concrete with the borosilicate glass and the amorphous boron steel fiber were investigated. The measures of this investigation includes air contents, slump loss, compressive strength, static modulus of elasticity, compressive toughness, flexural strength, flexure toughness and neutron shielding rate. As a result, the neutron shielding rate of the concrete with borosilicate glasses increased even though the compressive strength and flexural strength decreased in comparison with that of plain concrete. Also, the mechanical toughness and the neutron shielding rate of the concrete with amorphous boron steel fiber increased in comparison with that of plain concrete.
