Concrete volume stabilizer is a new type of concrete admixture product specially developed according to the difficult problems of poor volume stability and affecting concrete durability commonly existing in modern concrete. Concrete stabilizer can form a dense gel layer on the concrete surface, thus improving the impermeability and corrosion resistance of concrete. Stabilizers for concrete need to apply for CE certification in accordance with the EU CPR regulations, based on the coordinated standard EN 934-2:2009+A1:2012. They can only be sold in the EU market after passing the EU CPR CE certification. Nanjing Smart is an authorized cooperative institution under the EU Announcement Number, which can directly accept the EU CPR CE certification for stabilizers (concrete admixtures), including factory audits and product testing. Looking forward to your consultation and communication, hotline +86 25-8658 3475.
