摘要
阐述了低场核磁共振技术在水泥基材料研究中的应用现状,认为现有的研究主要集中于水泥水化进程和水在硬化浆体中的扩散特征,也包括对硬化水泥浆体孔结构和比表面积的测试。分析了低场核磁共振技术在实际应用中面临的挑战,展望了该技术在新拌水泥浆体结构性能研究中的应用前景。
The current applications of low field NMR in cement based materials are demonstrated. It is found that researches are focused on cement hydration and water diffusion in hardened cement paste, as well as pore size distribution and specific surface area of hydrated cement paste. Challenges in the current research are analyzed and the future applications of low field NMR in research on fresh cement paste are forecast.
