对掺加粉煤灰和矿粉后混凝土性能进行了试验研究，结果表明：28 d后所有掺加矿物掺合料的混凝土强度都已超过基准混凝土强度，7、60 d时，单掺35%粉煤灰强度最大，28 d时单掺35%矿粉效果最佳；各矿物掺合料均能改善混凝土各龄期的抗氯离子渗透性能，且掺量越高，抗渗性能越强，养护7 d时单掺50%矿粉效果最佳，而单掺50%粉煤灰对28、60 d时抗渗性能的改善最为明显；复掺粉煤灰和矿粉并没有较单掺显现出明显的优势。

The performances of concrete mixed with fly ash and slag were studied ,and results showed that:after 28 d the strength of all concrete mixed with mineral admixture have exceeded the strength of reference concrete.At 7 d and 60 d ,the strength of concrete mixed with 35%fly ash is the highest.At 28 d,mixing with 35%slag,the effect is the best;all mineral admixtures can improve the anti-chlo-ride-permeability performances of concrete in every age.And the content of admixture is higher ,the anti-permeability performance is more stronger.At 7 d,the effect with 50%slag is best,but at 28 d and 60 d the anti-permeability performances improved significantly when the proportion of fly ash is 50%;The double-doped of fly ash and slag showed no obvious advantage than doped of fly ash or slag only.
