the concrete composition for radioactive waste
The present invention relates to a heavyweight concrete composition for a radiation shielding structure. The concrete composition is configured to include 18 to 22 parts by weight of copper slag, 25 to 29 parts by weight of 19 mm aggregate, 11 to 15 parts by weight of 9.5 mm aggregate, 8 to 12 parts by weight of sand, and 7 to 9 parts by weight of water with respect to 20 to 24 parts by weight of cement or 20 to 24 parts by weight of copper slag, 28 to 32 parts by weight of 9.5 mm aggregate, 8 to 12 parts by weight of sand, and 6 to 10 parts by weight of water with respect to 28 to 32 parts by weight of cement. The concrete composition is used in the radiation shielding structure such as radioactive waste disposal containers, radioactive waste disposal warehouses, and radioactive material storage containers. A concrete structure based on the concrete composition satisfies a high level of unit weight of at least 2.5 tons per cubic meter by means of the copper slag and aggregate it includes. It provides a high level of stability, a high level of durability, and a high level of strength while safely shielding, disposing of, and storing radioactive wastes or radioactive materials.
본 발명은 따른 방사성 차폐 구조물용 고중량 콘크리트 조성물에 관한 것으로, 시멘트 20∼24 중량부에 대해서, 동슬래그 18∼22 중량부, 19㎜ 골재 25∼29 중량부, 9.5㎜ 골재 11∼15 중량부, 모래 8∼12 중량부, 물 7∼9 중량부로 구성하는 콘크리트 조성물, 또는, 시멘트 28∼32 중량부에 대해서, 동슬래그 20∼24 중량부, 9.5㎜ 골재 28∼32 중량부, 모래 8∼12 중량부, 물 6∼10 중량부로 구성하는 콘크리트 조성물을 구성하여, 상기 콘크리트 조성물을 방사성 폐기물용 처분용기, 방사성 폐기물의 처분고, 방사성 물질의 저장용기 등의 방사성 차폐 구조물에 사용되어, 콘크리트 조성물에 의한 콘크리트 구조물은 포함된 동슬래그와 골재에 의해서 2.5ton/㎥ 이상의 높은 단위중량을 만족하고, 방사성 폐기물이나 방사성 물질을 안전하게 차폐, 처분 및 저장하면서 높은 안정성을 가지고, 우수한 내구성과 강도를 가지는 것이다.
