摘　　要：为了利用某水电站附近电厂堆灰场的灰渣和磷矿渣,对磨细灰渣和磷渣进行了混掺(简称双掺料),对掺双掺料和掺粉煤灰的胶砂性能,碾压混凝土力学、变形、耐久性能及热学性能进行了对比试验分析,结果表明双掺料可用作碾压混凝土的掺合料。In order to use ash residue and phosphorous slag from the ash yard near a hydropower station,grinding slag and phosphorus slag are mixed('double admixture5 for short).The mechanical,deformation,durability and thermal properties of RCC with double admixtures and fly ash were compared and analyzed.The results show that the double admixtures can be used for RCC admixtures.
