Abstract Different solid phases, important to cement paste hydration, are investigated with low-field benchtop 1H nuclear magnetic resonance (NMR). A combination of the well-established quadrature echo pulse sequence with variable pulse gap together with a T1 saturation recovery quadrature echo pulse sequence is used. The results illustrate the diversity in the 1H NMR relaxation behaviour of solid phases that prospects the differentiation in more complex materials. We propose a procedure to obtain quantified values of the solid compounds using these unique relaxation responses of solids, called finger print, and apply this technique to well-hydrated white and ordinary Portland cement paste. Based on the results, needs and ways for future improvements are discussed.

1H核磁共振弛豫法定量测定水化水泥浆体中的固相

摘要 用低场台式 1H 核磁共振 (NMR) 研究了对水泥浆水化很重要的不同固相。使用成熟的具有可变脉冲间隙的正交回波脉冲序列与 T1 饱和恢复正交回波脉冲序列的组合。结果说明了固相的 1H NMR 弛豫行为的多样性，这预示着更复杂材料的差异化。我们提出了一种使用固体的这些独特弛豫响应（称为指纹）获得固体化合物量化值的程序，并将该技术应用于水化良好的白色和普通波特兰水泥浆。根据结果​​，讨论了未来改进的需求和方法。
