STUDY ON APPLICATION OF CLINKER FREE CONCRETE TO ROLLER COMPACTED CONCRETE PAVEMENT

Abstract

In this study, we perform a flesh property examination and a strength examination for application of Clinker Free Concrete（CFC）which doesn’t include any cement, to roller compacted concrete pavement（RCCP）. CFC’s water-powder ratio is 20％（W/P＝20％）and powder content is 500（kg/m³）. 5 types of mixed ratio of ground granulated blast-furnace slag and fly ash, and two types of mortar-coarse aggregate volume ratio were used for CFC. Two types of curing time were changed at this study. As a result of this study, the flexural strength of clinker free concrete of 12 hours age showed over 3.5 N/mm². And that of 28-days age showed over 4.5N/mm². The flexural strength increased with the increase of BS’s mixed ratio. There is the best Curing temperature of clinker free concrete.
