| 摘 要： | 研究了碱当量(以氧化钠当量计)、水胶比和胶砂比对碱矿渣水泥砂浆抗碳化性能的影响,并与硅酸盐水泥砂浆进行了对比试验。结果表明:在相同水胶比条件下,碱矿渣水泥砂浆比硅酸盐水泥砂浆更易碳化,且水胶比越大,胶砂比越小,碳化越严重。在3%～6%范围内,随着碱当量的增加,碱矿渣水泥砂浆的碳化程度减小。扩展度相当时,水玻璃为碱组分的碱矿渣水泥砂浆的抗碳化能力强于硅酸盐水泥砂浆。

| Abstract: | The influences of alkali equivalen(tcount as Na2O),water-binder ratio and binder-aggregate ratio on the carbonation of alkali-activat-ed slag cement mortar were studied.Results show that alkali-activated slag cement mortar was more easily carbonated than Portland cement mortar when water-binder ratio was the same,and the higher water-binder ratio or the lower binder-aggregate ratio,the deeper carbonation of alkali-acti-vated slag cement mortar.The carbonation depth of alkali-activated slag cement mortars de... |
