摘要/Abstract

摘要： 本文通过开展无侧限抗压强度试验探究固化剂配比(生石灰、高炉矿渣、粉煤灰占比)、固化剂掺量、养护龄期对生石灰激发高炉矿渣-粉煤灰地质聚合物固化土无侧限抗压强度(UCS)及变形模量的影响,并结合SEM-EDS微观测试揭示固化机理。结果表明:随着生石灰掺量增加,地质聚合物固化土无侧限抗压强度呈先增加后减小的趋势,增加高炉矿渣掺量可以有效提高固化土的无侧限抗压强度;地质聚合物固化土早期无侧限抗压强度提升速率大于水泥固化土,养护后期地质聚合物固化土无侧限抗压强度增长速率减小,但强度仍高于水泥固化土;固化土的变形模量随着高炉矿渣掺量、养护龄期的增加而增加,无侧限抗压强度和变形模量存在良好线性关系。生石灰激发下的地质聚合物生成的水化产物(C-S-H、C-A-S-H、C-A-H)能有效黏结土颗粒,促进致密固化土骨架结构的形成。研究结果为生石灰激发高炉矿渣-粉煤灰地质聚合物固化土在实际工程中的应用提供了理论参考。

Abstract: This study investigated the effects of stabilizer mix ratio(quicklime, ground blast furnace slag and fly ash proportion), stabilizer content, and curing age on the unconfined compressive strength (UCS) and deformation modulus of quicklime-activated ground blast furnace slag-fly ash geopolymer-stabilized soil through UCS tests. The stabilization mechanism was revealed through SEM-EDS microstructural test. The results indicate that the UCS of geopolymer-stabilized soil initially increases and subsequently decreases with rising quicklime content. Increasing ground blast furnace slag content effectively enhances the UCS of stabilized soil. The early-stage UCS development rate of geopolymer-stabilized soil exceeds that of cement-stabilized soil, while its strength growth rate decreases during later curing periods, yet maintains higher values than cement-stabilized soil. Both deformation modulus and UCS demonstrate positive correlations with stabilizer content and curing age, exhibiting a favorable linear relationship. The hydration products (C-S-H, C-A-S-H, and C-A-H) generated by quicklime-activated geopolymer effectively bond soil particles and facilitate the formation of dense stabilized soil skeleton structures. These findings provide theoretical support for practical applications of quicklime-activated ground blast furnace slag-fly ash geopolymer stabilized soil in engineering projects.

Key words: geopolymer, quicklime, unconfined compressive strength, mix ratio, curing age, stabilizer content, deformation modulus
