氯化铁防水剂可以防水砂浆及防水混凝土两种形式运用。1.防水砂浆:用于抹面防渗。如发现建筑物外部有渗漏痕迹,可在其内侧用防水砂浆抹面。待处理的部分要事先去掉附着的污物并用清水冲洗。砂浆防渗层由结合层、底层和面层组成。结合层的水泥、水、氯化铁防水剂的配比为1:0.3～0.35:0.03;底层的水泥、砂、水、氯化铁防 Ferric chloride waterproofing agent can be applied in two forms: waterproof mortar and waterproof concrete. 1. Waterproof mortar: used to wipe the surface to prevent seepage. If there are signs of leakage on the outside of the building, apply waterproof mortar on the inside of the building. The part to be treated is to remove the attached dirt in advance and rinse it with fresh water. The mortar impervious layer is composed of a bonding layer, a bottom layer and a surface layer. The ratio of cement, water and ferric chloride waterproofing agent in the bonding layer is 1:0.3 to 0.35:0.03; the cement, sand, water and ferric chloride in the bottom layer
