【摘要】 进行了掺粉石英水泥净浆试验 ,结果表明 :粉石英在标准养护条件下基本上不具火山灰活性 ;但在蒸压养护条件下具有明显的反应活性 ,其对混凝土的增强作用明显。对试件进行了XRD和SEM分析 ,结果显示粉石英在蒸汽压力为 1 2MPa、温度为 187℃的蒸压条件下 ,其反应半径为 2 μm更多还原

【Abstract】 Experiments were carried out with Portland cement mortar on the pozzulana properties of tripoli.The result shows that tripoli has evident pozzulana activity under autoclaving conditions but hardly does under ordinary curing conditions.XRD and SEM analyses reveal that tripoli has a reaction radium of 2μm under autoclaving conditions with a pressure and a temperature of 1.2MPa and 187℃ respectively.更多还原
