Introduction: Based on β-naphthalene sulfonate formaldehyde condensate, Point-400 concrete superplasticizer (standard type) is a compound with performance of high water reduction, high early strength and enhancement of concrete compressive strength rate, and able to significantly improve the workability of concrete mixture.

Features:

High dispersion: Based on the result measured according to national standard GB 8076-2008 “Concrete Admixture”, with dosage of 1.8%, it can have a water reduction rate of 22% and excellent filling-ability if applied in preparation of high strength and ultrahigh strength concrete.

Excellent workability: It can effectively enhance the flowability of concrete and reduce bleeding and separation to improve concrete compatibility, and thus make concrete convenient for pumping and easy to compact.

Excellent reinforcing: At the same dosage of unit cementitious material, with water dosage of 1.5%, the 3d and 28d compressive strength of the concrete with Point-400 standard type is generally 60~80% and 20~40% respectively higher than those of reference concrete of corresponding period.

Excellent durability: Point-400 standard type can effectively improve the pore structure of concrete and significantly enhance the durability indexes such as anti-permeability, anti-carbonation, wetting-drying cycle resistance, and freezing and thawing resistance.

High adaptability: The product is well adapted to various types of cement, expanding agent fly ash and grinded slag.

Safety properties: Non-toxic, non-irritant, non-radioactive, nonflammable, non-explosive, non-dangerous, and no corrosive to steel bar.
