摘　　要：针对矿物掺合料粉煤灰单掺,粉煤灰与硅粉、矿粉、石粉双掺对混合骨料混凝土抗压强度、抗渗性能进行了试验研究。结果表明:矿物掺合料双掺比粉煤灰单掺能有效提高混合骨料混凝土的28d抗压强度,但是对后期强度的影响未必都是正效应,粉煤灰与硅粉双掺56d抗压强度较高。加入矿物掺合料均可以提高混合骨料混凝土的抗渗性能,双惨组比单掺粉煤作用结果更明显,粉煤灰与硅粉双掺抗渗性能最优。综合考虑,粉煤灰与硅粉双掺是配制高性能混合骨料混凝土重要途径之一。For mineral admixtures only mixing fly ash,fly ash and silica fume,slag,lime stone powder double mixing cement mixture of aggregate concrete compressive strength,anti-permeability performance were studied.The results show,mineral admixtures double mixing fly ash than only mixed can effectively enhance the mixed aggregate concrete compressive strength of 28 d.but late on the influence of strength all is not positive effect,fly ash and silica fume double mixing 56 d compressive strength is higher.Join mineral admixtures are mixed aggregate concrete can improve its anti-permeability,double miserably group than in the only mixed adding more obvious action results,And fly ash and silica fume double mixing anti-permeability optimal performance.Overall consideration,fly ash and silica fume double mixing is mixed by high performance important way of aggregate concrete.
