研究了花岗岩石粉、粉煤灰、石屑石粉单掺(10%、20%、30%)，以及双掺对混凝土收缩抗裂各项性能的影响。结果表明，花岗岩石粉、石屑石粉掺量20%、粉煤灰掺量30%为最优掺量，花岗岩石粉与粉煤灰、石屑石粉与粉煤灰均按1：2双掺最优。

The influences of single doped 10% granite powder, 20% fly ash or 30% stone chip powder and double mixing 20%of the granite powder and fly ash or 20%of stone chip powder and fly ash on the shrinkage and crack proper-ties of concrete are studied. The results show that the optimal content of the granite powder, stone chip powder and fly ash is 20%, 20%and 30%respectively;the co-doped optimal proportions of the granite powder and fly ash, stone chip powder and fly ash are the same, all 1:2.
