摘　　要：由于便于就地取材,在实际工程应用中,以矿渣、石灰石粉作为混凝土掺合料较为普遍。针对糯扎渡水电站工程,通过对铁矿渣与石灰石粉掺配的掺合料进行试验研究,优选双掺料品种、掺量及掺配比例,进一步改善了混凝土的性能。Taking the mixture of iron slag powder and lime stone powder as concrete admixture has been commonly used in recent years in the construction of hydropower projects because of its accessibility. In the construction of Nuozhadu Hydropower Station, the concrete admixture consisted by iron slag powder and lime stone powder is researched by tests, and the varieties, contents and the mixing proportion of double admixtures-powder are also proposed to further improve the performance of concrete.
