摘要
水泥水化过程决定水泥基材料强度、耐久性等诸多性能,深入理解水泥水化机理具有重要的科学意义和工程价值。本工作回顾了硅酸盐水泥水化动力学模型的最新研究进展,评述了GEMS热力学计算、HymoStruc3D和CEMHY3D等水化数值模拟方法及其局限性,总结了准弹性中子散射和核磁共振等先进测试手段在研究水泥水化过程中水态演变和孔结构发展中的具体应用,提出了该领域未来研究的趋势和挑战。
Cement hydration is a key process to determine most properties of cementitious materials.Clarifying the mechanisms of cement hydration intersects both academic and practical interests.Recent research work on Portland cement hydration kinetic models was reviewed.The hydration simulation models,such as GEMS thermodynamic calculation,HymoStruc3D and CEMHY3D and other hydration simulation models and their limitations were discussed.The application of quasi-elastic neutron scattering and nuclear magnetic resonance methods in the evolution of water states and the development of pore structure during cement hydration process were summarized.In addition,this review also gave the future developemt and challenges in this field.
