Studies were conducted using varying proportions of granite powder in canal lining concrete to determine the effect on compression resistance, impermeability and freeze–thaw cycling. The concrete microstructure was assessed using mercury intrusion porosimetry, scanning electron microscopy, and other methods. The data indicate the appearance of pore throats and demonstrate that a granite content of 10%–20% reduces the concrete strength, frost resistance, and impermeability based on changes at the microscopic level. An equation describing the relationship between the granite powder content and pore structure parameters (porosity, 20‐ to 200‐nm pore volume, and fractal dimension) was established.

花岗岩粉对混凝土性能的影响

在运河衬砌混凝土中使用不同比例的花岗岩粉进行了研究，以确定对抗压性，抗渗性和冻融循环的影响。使用压汞法，扫描电子显微镜和其他方法评估混凝土的微观结构。数据表明了孔喉的出现，并证明了10％–20％的花岗岩含量会根据微观水平的变化而降低混凝土强度，抗冻性和抗渗性。建立了描述花岗岩粉末含量与孔结构参数（孔隙度，20-200 nm孔体积和分形维数）之间关系的方程。
