摘要 C-S-H是水泥水化的主要胶凝材料,其结构直接影响混凝土工程性,由于其结晶度较低,中短程有序,采用固体核磁(NMR)可作为分析其结构的方法之一。本文从C-S-H的模型,NMR中特征参数,平均分子链长(MCL)和聚合度三个角度,对水化龄期、掺合料、钙硅比三个方面进行了综述,并展望了固体核磁技术在C-S-H中的发展趋势。 C-S-H is the primary strength-forming phase in Portland cement paste and significantly influences its mechanical and transport properties. A precise structural determination has not been performed because of the lack of homogeneous samples with long-range cristallinity. This paper reviews recent NMR concerning the model, MCL and polymerization degreeof calcium silicate hydrate （C-S-H） and the parameters of NMR, the prospective developments in NMR are anticipated.
