Finally using the model loading age and coarse aggregate, cementratio parameters were analyzed, and the laws of fly ash concrete creep are present.
最终运用本模型对加载龄期和粗骨料、水泥砂浆比参数进行了分析，给出了粉煤灰混凝土徐变的规律。

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.
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。
