Abstract

The influence of microstructure of silica-enhanced cement on the mechanical performance of cement is difficult to describe. In this study, we used the scanning electron microscope and image processing method to investigate the relationship between the complicity of cement microstructure and compressive strength under various temperatures and curing times. Fractal dimension was applied to describe the complicity of silica-enhanced cement. The relationships among compressive strength, fractal dimension, temperature, curing time and pore structure of cement were identified. The results show that curing time directly controls the complicity of microstructure of silica-enhanced cement and compressive strength by altering the pore orientation and macropore ratio in silica-enhanced cement. The curing temperature affects the complicity of cement microstructure and compressive strength indirectly by changing the ratio of micropore and small pore. The fractal dimension of silica-enhanced cement shows good correlation with compressive strength. Pore size distribution is the most important factor that influences the complicity of cement matrix and compressive strength of silica-enhanced cement. When building up the macroscopic mechanical performance model of silica-enhanced cement, we should consider the influence of pore size distribution in cement under different curing temperatures and times on the complicity of cement microstructure.

摘要

二氧化硅增强水泥的微观结构对水泥力学性能的影响难以描述。在本研究中，我们使用扫描电子显微镜和图像处理方法，研究了在不同温度和养护时间下水泥微观结构的复杂性与抗压强度之间的关系。分形维数用于描述二氧化硅增强水泥的复杂性。确定了抗压强度、分形维数、温度、养护时间和水泥孔隙结构之间的关系。结果表明，养护时间通过改变二氧化硅增强水泥中的孔隙取向和大孔比例，直接控制二氧化硅增强水泥微观结构的复杂性和抗压强度。养护温度通过改变微孔和小孔的比例，间接影响水泥微观结构的复杂性和抗压强度。二氧化硅增强水泥的分形维数与抗压强度具有良好的相关性。孔径分布是影响水泥基体复杂性和二氧化硅增强水泥抗压强度的最重要因素。在建立二氧化硅增强水泥的宏观力学性能模型时，应考虑不同养护温度和时间下水泥中孔径分布对水泥微观结构复杂性的影响。
