Compared with traditional melamine type Water-reducing additive, type WRA-1 Water-reducing Reinforcing Additive can increase water-reducing ratio 15% -20% , and the dry strength and wet strength of gypsum both can be increased 30% -200% .
After mixing type WRA-1 Water-reducing Reinforcing Additive into the gypsum, compared with mixing traditional melamine type water-reducing additive, the viscosity of gypsum slurry is smaller, solid content is higher, and it is more better for construction, keeping-water and fluidity.
Type WRA-1 Water-reducing Reinforcing Additive also has the common characteristics as traditional melamine type water-reducing additive, for example non air-entrainment, good steam-cured adaptability, no slow-setting action for gypsum, no rusting and corroding for reinforcing steel bar, innocuity, no pollution.
