Based on the corrosion or protective effects of different substances on cement,this study focuses on the influence of adding different proportions of ammonium sulfate to bitumen based wet-laid waterproofing membranes on the bonding performance between the wet applied membrane and the substrate.The results show that although ammonium sulfate has a certain degree of corrosiveness to the cement-based bonding layer,it can shorten the full adhesion time required for wet-laid construction,improve the bonding efficiency and increase the bonding strength,by controlling its dosage and having it added along with calcium aluminate powder and oxalate in a certain proportion into the self-adhesive modified bitumen compound of the bitumen based wet-laid waterproofing membrane.Under micro CT scanning,the bonding surface becomes denser.
