Retarding Admixture

The series of concrete Retarding Admixture can effectively delay the initial and final setting time of concrete without affecting its final physical and mechanical properties and durability. They are mainly applicable to large-volume concrete in water conservancy, nuclear power, roads, bridges, municipal and general industrial and civil buildings, as well as pre-mixed and cast-in-place concrete with retarding requirements. They are especially suitable for concrete with retarding requirements in the high-temperature summer season. It can also be used as an admixture to assist the plastic retention component. The series of products, when used in combination with water-reducing agents and other components, do not increase the viscosity of concrete, but have a certain stimulating effect on the initial fluidity, and help improve the plastic retention performance of water-reducing agents and pumping agents. The initial setting time can generally be delayed by 2 to 10 hours. The dosage can also be adjusted according to different engineering requirements, and super-retardation setting for more than 60 hours can be achieved.
