摘要
以AMPS(2-丙烯酰胺基-2-甲基丙磺酸)、二乙醇胺和硝酸钙为主要原料,利用正交试验设计的方法系统考察了早强剂的复配,以及早强剂对水泥浆性能的影响、水泥浆的稠化时间和其他外加剂的配伍性,并且通过XRD和SEM等手段表征了早强剂的结构,并对该早强剂的早强效果及抗压效果进行了检测。结果表明:掺有质量分数5%早强剂的水泥石在1、3和7d的抗压强度比原浆水泥石分别提高了15.2%、14.3%和16.7%,在抗高温性能方面也得到了较大提高。
AMPS,diethanolamine,and calium nitrate as materials of early-strength accelerator were prepared and characterized.Orthogonal experiment was utilized to optimize optimum content of early-strength accelerator.The samples were characterized with powder X-ray diffraction(XRD) and SEM.It is shown that when the weight of 5% early agents were introduced,the 1,3 and 7 d of cement strength improved by 15.2%、14.3%、16.7%,respectively,which is also a further development in the high temperature.
