摘要
为探究不同碱性化学试剂对矿渣、粉煤灰的活性激发效果,选取NaOH、Na2CO3、Na2SiO3三种常见的碱激发剂,以单掺、复合掺两种方式得到了7种不同类型的碱激发剂,并制备了三组不同水胶比的净浆试件,通过测试试件3d、7d、28d时间的静态力学性能,对比发现由NaOH与Na2SiO3制备的复合碱能最有效地激发矿渣、粉煤灰的活性。
Three kinds of alkali were chosen to study the excitation characteristics of slag-fly ash, and 7 different kinds of alkali-activator were disigned by added one, two or three kinds of alkali. Three different water-binder ratio paste samples were prepared their static strength were tested after conserved 3 days, 7 days, 28 days, Results show that the alkali-activator constituted of NaOH and Na2SiO3 have the best per- formance.
