摘要:
采用固相法合成硅酸三钙(C3S)和阿利特,通过掺杂不同含量的MgO得到几种典型晶型的阿利特。利用X线衍射仪(XRD)测定阿利特的晶型,发现MgO掺杂量为0、0.5%、1.0%和2.0%(质量分数)时,阿利特在室温下能够分别以T1、T1+M1、M1及M3型稳定存在。通过Image-Pro-Plus(IPP)软件对阿利特水化早期(3、7及14 d)样品的背散射电子像进行定量分析,测定不同颗粒尺寸范围内4种晶型阿利特的水化程度。结果表明:对水化活性最敏感的粒径范围为>6~17 μm,水化早期4种晶型阿利特的水化活性由小到大依次为T1、T1+M1、M3和M1。
Abstract:
Tricalcium silicate(C3S)and alite were synthesized by a solid-state method.Some typical modifications of the alite were obtained by doping different amounts of MgO and were characterized with X-ray diffractometer(XRD).Results showed that T1,T1+M1,M1, and M3 modifications of alite were stabilized at room temperature when doped amounts were 0,0.5%,1.0% and 2.0% MgO, respectively.The backscattered electron composition image(BEC)of early hydration periods(3,7 and 14 d)of the alite were quantitatively analyzed by using Image-Pro-Plus(IPP)software,and hydration degrees of the alite of different particle size ranges with 4 different modifications were measured.Results showed that the most sensitive particle size ranges to the hydration activity were >6~17 μm,and the hydration activity for the 4 alite modifications in early hydration periods was in the orders of T1,T1+M1,M3, and M1.
