| Abstract: | The effects of recycled aggregate quantity,PFA replacing cement quantity,PFA over-replacing quantity and water cement ratio on PFA regeneration concrete compression strength were studied.Orthogonal experiment results show that water cement ratio is the main factor that influences PFA regeneration concrete stregth and recycled aggregate quantity is subordinate factor.The optimum mix ratio of PFA regeneration concrete is advanced by orthogonal analysis. |
