High Range Water-reducing Admixture

The High Range Water-Reducing Admixture is the non-air entraining high range water reducing admixture by chemical combining. The chemical name is I -naphthalene sulphonic sodium formaldehyde admixture. It has a powerful dispersion effect for the cement particle. It can improve the performance of the concrete and good for the preparation of the great liquid concrete the precast component and the cast-in-place concrete which demand the early strength and high strength it applies for road bridge dam port dock tunnel electric project and water project industry civil construction steam curing and nature curing precast component etc.
Homogeneity of Norms:

Principal Technical Performances:
1. The mixing amount is 0.5-1.5% of the cementitious material; the water-reducing rate is 12-28%. This product has clear early strength and reinforced effect concretea s strength will improve 60-130% for 3 days improve 40-60% for 7 days improve 20-40% for 28 days and the strength will be increased for a long period.
2. This product can save cement 15-20% than the concrete without the water reducing admixture in keeping the same intensity and slump of concrete.
3. Mixing this product can greatly improve the workability and the mechanical performance and improve the anti-pressure anti-pull a
