Dosage
Form/Color: Powder/ light brown; Liquid/brown
Dosage (total cementitious materials): Powder: 0.5~1.0%; Liquid: 1.0~2.0%.
Increase dosage when manufacture high strength concrete.
The optimum mix design needs to be determined by the requirements of the project, specialties of materials and mixture tests before usage.
Powder admixture can be added with binding materials, liquid with mixing water. Increase mixing time properly. The powder admixture can be dissolved into water as liquid mixture.
Packing
Powder: 40kg/bag
Liquid: 200~250kg P.E. drum or IBC Tank
