H-503 Corrosion-resistance agent

By adding corrosion-resistance agent, the concentration of SO42- ions invading into concrete can be effectively reduced, the pores can be refined, the expansion damage can be restrained, and the speed of sulfate corrosion damage of concrete can be delayed, so as to improve the durability of concrete.
◆ It has outstanding effect in preventing corrosion damage of concrete and improving the early strength of concrete.
◆ Increase the compactness of the concrete and improve the impermeability grade of the concrete ◆The concrete enhances the ability to resist the corrosion damage of magnesium ions
◆ Improve the frost resistance of concrete
