摘　　要：本文综述了碱激发矿渣、碱激发粉煤灰、碱激发矿渣粉煤灰以及其它碱激发胶凝材料中的碱硅反应研究进展。在相同条件下,碱激发矿渣砂浆棒或混凝土棱柱体的膨胀值通常比硅酸盐水泥材料的小,取决于碱激发剂种类、活性骨料的种类和尺寸等。碱激发矿渣的碱硅反应并不随碱掺量的增加而变大,存在碱掺量最劣值。用粉煤灰或偏高岭土来取代矿渣可减小甚至抑制碱激发矿渣中碱硅反应的发生。Research preogesses in alkali silica reaction of alkali activated slag materials, alkali activated fly ash materials, alkali activated slag-fly ash materials and other alkali activated materials were reviewed. The expansion of mortar bar and concrete prism made from the alkali activated slag, which is influenced by the types of alkali activator, the type and size of reactive aggregates, is usually less than that made from Portland cement materials under the same conditions. The alkali silica reaction of alkali activated materials does not increase with the increase of alkali dosage, but exists a pessimistic value. The replacement of slag with fly ash or metakaoline can inhibit alkali silica reaction in alkali activated slag materials.
