Abstract: 29 Si solid-state Nuclear Magnetic Resonance ( NMR) technique is one of the effective tools in researching for quantitative analysis of cement-based materials , which is widely used in cement chemistry .In order to highlight the advantages of 29 Si NMR in cement chemistry , this article started with the modern analytical and testing techniques , and then combined quantitative analysis technics and data of 29 Si NMR.More importantly , this paper reviewed the application of 29 Si NMR in quantitative analysis of mineral composition of Portland cement clinker , cement hydration process and quantitative characterization of cement-based materials such as gypsum admixing silica fume .The problem of 29 Si NMR technique applied in cement quantitative analysis was proposed and the development of 29 Si NMR in cement-based materials was evaluated objectively .
