地聚物是通过化学激发生成的具有低碳属性的新型胶凝材料, 具有部分取代水泥的巨大潜力。本文通过压汞试验表征了偏高岭土-矿渣地聚物净浆及砂浆的孔隙结构, 分析了液固比、砂体积分数等因素对孔结构特性的影响, 明确了孔结构特性与面分形维数的相关性。采用氯离子非稳态电迁移试验、非稳态自然扩散试验和水分扩散试验, 研究了偏高岭土-矿渣地聚物净浆与砂浆的抗渗透性能, 分析了液固比、砂体积分数及孔面分形维数与浆体介质传输性能的相关性。结果表明: 随着液固比增大, 地聚物净浆的孔隙率和最可几孔径均增大, 抗渗透性能降低; 地聚物砂浆的抗渗透性能优于水泥砂浆, 砂体积分数增加时, 地聚物...

Geopolymer is a novel cementitious material with low carbon properties produced by chemical activation,which has great potential to partially replace cement.The pore structure of metakaolin-slag geopolymer paste and mortar was characterized by mercury intrusion porosime...MORE Geopolymer is a novel cementitious material with low carbon properties produced by chemical activation,which has great potential to partially replace cement.The pore structure of metakaolin-slag geopolymer paste and mortar was characterized by mercury intrusion porosimetry tests.The effects of liquid-solid ratio and sand...
