水泥水化程度指在一定时间内水泥水化量与水泥完全水化量之比。对于纯水泥体系中水泥水化程度的研究,国内外学者已做了大量的工作,并形成了一系列较为成熟的理论和方法,如:水化热法,化学结合水法,CH定量测试法,水化动力学法等。对于掺加粉煤灰、炉渣、石灰石、高钛渣等混合材的水泥基胶凝材料体系,传统的方法对水泥的水化程度的测试存在一些偏差。本文综述了几种传统的水泥水化程度研究方法以及尝试了几种新的方法(包括TG-DSC、压汞MIP、烧失量LOI、背散射电子图像法BEI、XRD和SEM等)。此外,通过对不同的研究方法得到的结果比较,为进一步研究复合胶凝体系的水化过程提供了理论依据,并提出了水泥基材料的测试方法的局限及发展需求
The hydration degree of cement means the ratio of the hydration of cement quantity and the completely hydration of cement quantity in a certain period of time. For the study of hydration degree of pure cement system, domestic and foreign scholars have done much work, and formed a series of mature theory and method, such as: hydration heat, non-evaporable water, CH quantitative measurement, cement hydration kinetic model etc. For the cement-based materials system with fly ash, slag, limestone, high titanium slag and other admixture, there are some deviations in the traditional test method for the hydration degree of cement. This paper reviews some conventional methods of the cement hydration degree and tries some new methods including TG-DSC, mercury (MIP), ignition loss (LOI), backscattered electron imaging method (BSE), XRD and SEM etc. In addition, through the comparative study on the results of different research methods, this paper provides a theoretical basis for further study on the hydration process of composite cementitious system, and put forward the limitations and the demand of the development of test methods of cement based materials |
