CONCRETE COMPOSITION FOR ROLLER COMPACTED CONCRETE PAVEMENT (RCCP)

摘要

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.;COPYRIGHT KIPO 2017
