| Chemical Expression |
The raw material naphthalene superplasticizer (SNF/FDN/PNS) has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast-in-situ concrete and precast members with early strength and high strength requirements, can comprehensively improve various properties of the concrete, and is widely applied to highways, bridges, dams, harbors, tunnels, electric power, water conservancy as well as industrial and civil architecture, steam-cured and naturally-cured precast members and so on. | ||
| Dosage | Dosage: Powder dosage is 0.75% - 1.5%, liquid dosage is 1.5% - 2.5% | ||
| Test items | Specifications |
| Model | SNF-C |
| appearance | Light brown powder |
| Solid content | ≥93% |
| PH value | 7-9 |
| Sodium sulfate | <18% |

| The influence of sodium sulfate content on concrete: 1. If the content is large, it may crystallize at low temperature which blocks pipes and valves, and reduces the water reducing capacity and strength.Because the solubility is affected by temperature change.When the outdoor temperature is below 20ºC, the solubility will drop suddenly. When the outdoor temperature is below 16ºC, the crystal of sodium sulfate is obvious.During crystallization, some effective components of naphthalene series superplasticizer will be adsorbed, which will affect the water reducing ability and strength of concrete. |
|
| The effect of chloride ion content on reinforcement: Chloride ion is the catalyst of corroded steel bar, which will not be consumed in the process of corrosion. If the content of chloride ion in the admixture is too high, it will accelerate the corrosion of steel bar and affect the strength of concrete |
