Research and Application of Different Rage Fly Ashes in Recycled Concrete

Abstract:

In this paper, it was introduced that the case that under100% replacement of recycled coarse aggregate (RCA), the C30 recycled concrete was prepared by different rage fly ashes 0%, 10%, 20%, 30% replacing cement. The strength of the recycled concrete and mixtures workability were test. Eventually it is concluded that the strength and mixtures workability of recycled concrete were affected by different circumstance under the different rage and amount of fly ashes, and a theoretical basis in the impact of fly ashes in the application of recycled concrete is provided.
