Chemical name: Naphthalene Sulfonate Formaldehyde Condensate (Na2SO4≤3%,5%,18%,22%)
Appearance: Light yellow powder
Molecular formula: C21H14O6S2.2Na
CAS Number: 36290-04-7
1, Main ingredient is β-naphthyl sulfonate formaldehyde condensate, sodium sulfate≤2.0%.5%,10%,18%
2, Good dispersion, water reduction and early-strength effect. It can speed up the turnover of templates and fields, accelerate construction progress and shorten the completion period. It is applicable for concrete with early-strength and high-performance requirements and other concretes that need to enhance strength and improve long term performance.
3, Increase the concrete slump and improve its liquidity, applicable for ready-mixed concrete, pumping concrete, high-liquidity concrete, grouting material, etc.
4, Without air entraining. It is applicable for all grades of concrete with steam curing condition and natural maintenance.
5, No corrosion on steel bars. It is applicable for precast concrete, cast-in-place concrete, reinforced concrete, prestressed reinforced concrete, etc. in various projects.
6, Good compatibility with portland cement, regular portland cement, portland slag cement, portland flyash cement, etc.
II, Performance
1,Powder or liquid. The powder appears to be brownish yellow, and the liquid appears to be tan. Both are nontoxic, odorless and incombustible.
2,Blend dosage 0.3-1.5% for powder (as cement amount), recommended blend dosage 0.75% for powder (as cement amount).
3,When added into concretes: While keeping the cement consumption and slump unchanged, water reduction will reach more than 22%, and increase 1d compressive strength of concrete up to 60-100%, 3d compressive strength up to 50-90% and 28d compressive strength up to 30-50%, to be further reinforced in later period.
A. While keeping the water-cement ratio and water consumption unchanged, concrete slump can be increased by more than 120mm.
B. While keeping the slump and compressive strength basically unchanged, consumption of cement can be saved by over 18%.
C. The durability and other properties of concrete can be evidently increased and improved.
