The influence of physical activated and chemical activated fly-ash on the strength and paste structure of portland cement was studied by XRD, SEM and measuring strength etc. 利用XRD,SEM,力学性能测试等手段,研究了物理活化和化学活化粉煤灰对硅酸盐水泥强度及其浆体结构的影响;
The comprehensive study on the impact and mechanism of mineral fillers, as fly-ash, Portland cement, slag-powder, hydrated lime and so on, improved asphalt concrete stability is scarce. 对于替代矿粉使用的粉煤灰、水泥、矿渣粉、石灰等填料对沥青混合料性能的改善效果及机理缺乏系统的研究。
The test results show that alkali-activated slag and fly-ash cementing materials have good acid resistance, while ordinary Portland cement and alkali-activated metakaolin have low acid resistance. 碱激发胶凝材料耐酸实验结果表明,碱-矿渣和碱-粉煤灰胶凝材料具有良好的抗侵蚀性能,水泥和偏-偏高岭土胶凝材料的抗酸侵蚀性能较差。
