摘要
研究了再生骨料掺量、粉煤灰取代水泥量、粉煤灰超量系数和水灰比对粉煤灰再生混凝土抗压强度的影响。正交试验表明 ,水灰比是影响粉煤灰再生混凝土强度的主要因素 ,再生骨料掺量是次要因素 ;通过正交分析 。
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.
