水泥基渗透结晶型防水材料
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and marking for cementitious capillary crystalline waterproofing materials. It is applied in the construction industry for waterproofing concrete structures such as basements, tunnels, water treatment facilities, and bridges, where it reacts with moisture to form crystalline deposits that seal pores and cracks. The standard ensures consistent performance for materials used in both new construction and repair of existing concrete.
