摘   要：通过在高铝水泥中掺入不同掺量（5%、10%、15%、20%）的石灰石、石膏、粉煤灰、矿渣四种矿物掺合料，研究其对高铝水泥的强度影响及水化作用机理。结果表明，四种掺合料均能不同程度抑制高铝水泥后期强度倒缩；石灰石、石膏、粉煤灰、矿渣的最佳掺量分别为10%、15%、5%、5%。掺入10%的石灰石、15%的石膏时，高铝水泥的3d强度分别提高6.80%、4.25%，28d强度分别提高11.63%、8.80%；掺入5%的粉煤灰时，28d强度提高9.91%；矿渣的掺入不能提高高铝水泥各龄期强度。

Abstract: In order to study the effect of mineral admixture on strength and hydration mechanism of high alumina cement, four kinds of mineral admixture of different dosage(5%, 10%, 15% and 20%) of limestone, gypsum, fly ash and slag were used to replace high alumina cement paste. The results showed that the four kinds of admixtures are different degree of inhibition of high alumina cement later strength reduction. The optimum quantity of limestone, gypsum, fly ash and slag is 10%, 15%, 5% and 5% respectively. When 10% limestone, 15% gypsum were used to replace high alumina cement paste, the compressive strength of high alumina cement at 3d was improved 6.80% and 4.25% respectively, and the compressive strength at 28d increased by 11.63% and 8.80% respectively. When 5% fly ash was used to replace high alumina cement paste, the compressive strength at 28d was improved 9.91%. Slag can’t improve high aluminum cement strength.
