The analysis on strength and fly ash effect of roller-compacted concrete with high volume fly ash

摘要: In this paper, the strength of roller-compacted concrete with high volume fly ash (HFRCC) is examined. By using notion specific strength, qualified contribution effect to construction formation and development HFRCC also analyzed. The research results show that: (1) at early ages poor, while low or negative. (2) increases rapidly following its curing age; meanwhile, gradually improves more beneficial raising flexural strength. (3) With increasing proportion ash, on long age becomes remarkable.
