    摘要:制备了掺玄武岩石粉的碱激发矿渣胶凝材料,研究了玄武岩石粉掺量、液固比、碱激发剂的固含量和模数对碱激发矿渣胶凝材料抗压强度的影响。结果表明:随着玄武岩石粉掺量的增加,碱激发矿渣胶凝材料的抗压强度呈下降趋势;碱激发剂的固含量由18.00%增大至35.58%时,所制材料的抗压强度呈提高趋势,但碱激发剂的固含量进一步提高至41.35%时,碱激发矿渣胶凝材料的抗压强度反而较低;碱激发剂的固含量为25.08%~35.58%、模数为1.50~1.00时,可制得强度较理想的玄武岩石粉-矿渣碱激发胶凝材料。

    Abstract:This paper aimed to fabricate alkali -activated slag with basalt stone power. The effect of basalt stone power dosage,mass ratio of alkali activator to solid power,solid content of the alkali activator on the compressive strength of alkali-activated cementitious material were investigated. The results showed that with the increase in dosage of basalt stone power,the compressive strength of the materials decreased. With solid content of alkali activator increase from 18.00% to 35.58%,the compressive strength of the materials increased. However,the corresponding strength decreased with further increase in solid content of alkali activator to 41.35%. Alkali-activated cementitious materials with desirable compressive strength could be obtained with using alkali activator with a solid content and modulus ranging between 25.08% and 35.58%,and between 1.50 and 1.00,respectively.
