土木建筑工程

• 抗渗性

  Fast freeze-thaw method is used in frost resistance test,hydrostatic pressure method and chloride penetration method are used in impermeability test,and ball bearing method is used in abrasion resistance test.

  抗冻性试验采用快冻法,抗渗性试验采用静水压力法和氯离子渗透法,耐磨性试验采用滚珠轴承法。

• 渗透

  A suitable amount of water reducer can improve the pore structures of concrete, increase the concrete compactness and impermeability, and decrease the corrosion rate of rebars in concrete.2.

  适量的萘系减水剂有利于改善混凝土的孔隙结构,增强混凝土的密实性和抗渗透性能,从而减缓试样的钢筋腐蚀。

交通运输工程

• 抗渗性

  The effect of pipe grouting that can be confirmed through situ-testing and laboratory, testing can be represented by the impermeability and intension of surrounding-rock.

  注浆效果是通过围岩的抗渗性和强度体现出来的，效果确认可以通过现场原位试验和实验室试验进行。
