These catalytic mechanisms of interfacialagent in some chemical reactions are micelle catalysis and phase transfer catalysis.
表面活性剂催化化学反应过程的机理有胶束催化和相转移催化。

Bond plane is the tache of weakness for the new and old concrete bond structure when withstanding shear force and tension. Appropriate interfacialagent can improve bond strength.
当承受剪力和拉力时，粘结面是新老砼粘结结构受力的薄弱环节，使用合适的界面剂可以提高其粘结强度。

As interfacialagent, the mix of cement and fly ash can improve the adhesive shear strength. After planted reinforced bar, the shear strength of new and existing concrete increases greatly.
