Provided is a concrete composition for roller compacted concrete pavement (RCCP), which contains: cement in a unit of 270-290 kg/m^3; water in a unit of 140-150 kg/m^3; 1200-1400 kg/m^3 of fine aggregates; and 800-1000 kg/m^3 of coarse aggregates. The rate of fine aggregates ranges from 55 to 65, and the content of a water reducing admixture is 0.1-1.5 parts by weight with respect to the cement. According to the present invention, it is possible to secure sufficient amount of time of operations for voltage compaction and transportation of the concrete composition.
본 발명은 단위 시멘트량 270~290㎏/㎥; 단위수량 140~150㎏/㎥; 잔골재 1200~1400㎏/㎥; 굵은골재 800~1000㎏/㎥;를 포함하고, 잔골재율은 55~65이며, 감수제는 상기 시멘트 대비 0.1~1.5중량부가 혼입된 것을 특징으로 하는 RCCP용 콘크리트 조성물을 제시함으로써, 콘크리트 조성물의 운반 및 전압다짐을 위한 충분한 작업시간의 확보가 가능하도록 한다.
