Water-Reducing Reinforcing Additive For High-Strength Gypsum, Cement & Concrete

Shenzhen Chenggong Building Materials Co., Ltd. supplingtype WRA-1 Water-reducing Reinforcing Additivefor making high-strength Land Plaster & Gypsum products, high-strength cement and concrete products.

Compared with traditional melamine type Water-reducing additive,type WRA-1 Water-reducing Reinforcing Additivecan 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 Additiveinto 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 Additivealso 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.

It is suitable for making high-strength land plaster, building land plaster of bigger water-requirement in standard consistence, special for chemical land plaster and its goods.

Recommended mixed quantity: 0. 2% to 0. 6% of gypsum powder weight.

At the same time, Water-reducing Reinforcing Additive is aslo used in making high-strength cement and concrete. It can increase water-reducing ratio 20% -30% , can increase compressive strength (1 day) 45 to 100% at 20 Degree C., within 3 days can reach 70% of benchmark concrete.

Recomended quantity:

Generally, 0. 5 to 1. 0% of cement weight.
For high-strength refractory concrete, the mixed quantity is 0. 8 to 1. 2% .
