氟硅渣改性硫酸铝基无碱液体速凝剂对水泥性能的影响OA北大核心CSTPCD
Effect of Aluminum Sulfate Base Alkali-Free Liquid Accelerating Agent Modified by Fluorine Silicon Slag on Cement Properties
本文采用氟硅渣对硫酸铝基无碱液体速凝剂进行了改性,并测试了氟硅渣改性后无碱液体速凝剂的性能指标.采用XRD、TG-DTG和SEM表征手段分析了氟硅渣改性硫酸铝基无碱液体速凝剂对水泥水化过程的作用机理.结果表明:随着氟硅渣用量的增加,砂浆的快凝效果和强度均呈先增大后减小的趋势;用氟硅渣改性无碱液体速凝剂时,氟硅渣的掺量以5.0％(质量分数)为宜,此时掺改性速凝剂水泥试件的初凝时间为1 min 20 s,终凝时间为5 min 20 s,l d抗压强度…查看全部>>
In this paper,the aluminum sulfate based alkali-free liquid accelerating agent was modified by fluorine silicon slag,and the performance index of alkali-free liquid accelerating agent modified by fluorine silicon slag was tested.XRD,TG-DTG and SEM were used to explore the action mechanism of aluminum sulfate base alkali-free liquid accelerating agent modified by fluorine silicon slag on cement hydration process.The results show that with the increase of fluo…查看全部>>
