Effect of Fly Ash on Deformation of Roller-Compacted Concrete
|
In this paper, the effects of fly ash on the strength, shrinkage strain, and deformation of roller-compacted concrete have been described. The results show that fly ash can decrease the shrinkage strain and deformation of roller-compacted concrete. Thus, the cracks in a large concrete dam may be reduced when 50% fly ash is used.
Keywords: deformation; expansion; fly ash; roller-compacted concrete.
