    • 본 발명은 시멘트 몰탈 조성물 및 콘크리트 조성물에 관한 것으로, 특히 시멘트 100 중량부, 유리 비드 100∼300 중량부, 및 배합수 50∼200 중량부를 포함하는 것을 특징으로 하는 시멘트 몰탈 조성물 및 상기 시멘트 조성물에 골재를 더욱 포함하는 콘크리트 조성물에 관한 것이다.
      본 발명의 시멘트 몰탈 조성물 및 콘크리트 조성물은 종래 시멘트 몰탈 조성물 및 콘크리트 조성물에 비하여 소량의 배합수를 사용하면서도 유동성이 우수하여 철근과 기타 배관으로 복잡한 거푸집 내에서 중력방향으로 신속하게 이동하며, 골재사이 등 공간으로 침투하여 우수한 충진성으로 내외부의 기포를 제거하고 재료분리를 방지할 뿐만 아니라, 소량의 배합수가 배합된 몰탈(또는 콘크리트) 조직은 물의 이동경로인 모세관과 공극을 감소시켜 몰탈조직내로 물의 흡수, 확산, 및 흐름을 방지하므로 몰탈(또는 콘크리트)의 방수성을 현저히 향상시키고 열화를 방지할 수 있다. 뿐만 아니라, 발생된 수화열을 몰탈(또는 콘크리트)내에서 흡수함으로써 대량으로 타설하는 댐, 교량, 터널 등 토목구조물에서 수화열을 제어하기 위해 설치되는 냉각 시스템의 필요가 없으며, 몰탈(또는 콘크리트)의 표면장력을 낮추어 철강제품과의 친화력이 우수하므로 재료분리현상이 없고, 철근표면을 부동태로 바꾸어 부식으로 인한 구조물의 변형을 차단할 수 있을 뿐만 아니라, 연속시공으로 고품질의 공사를 실현할 수 있고, 시공후 초기 강도 도달시간이 짧아 공기가 단축되고 충진성이 뛰어나 마감면의 평활도가 높고 기포 등의 요철이 없어 고품질을 실현할 수 있다.
