Model No.:  SNF

Product Description

Model NO.: SNF Classification: Chemical Additives Appearance: Powder Sodium Sulphate: 5-18%: Surfactant Sample: Freee Trademark: Yuansheng Chemical Origin: Shandong, China Efficacy: Concrete Water Reducers Type: Sulfonated Naphthalene Formaldehyde Condensate Color: Brown Packings: 25kgs Appearances: Brown Specification: SGS HS Code: 382440100 Sodium Naphthalene Sulphonate Formaldehyde (SNF) is a kind of concrete auxiliary chemicals, can be used as construction building materials, put it into cement can enhance the liquidity. It also known as Concrete Admixture, concrete additives, concrete agents, construction materials, cement additives, high range water reducing agents, dispersing agent, etc

Some form of the name:
Sodium naphthalene sulphonate formaldehyde/ naphthalene sulfonate formaldehyde condensate/ naphthalene sulfonate formaldehyde/SNF/PDN/DNS

Product performance:
1. Reduce 10 to 25 percent of cement content when the strength and the slump of the concrete are basically same.
2. When the water cement ratio is constant, it improves the initial slump of the concrete by more than 10cm, and the water-reducing ratio can reach 15 to 25 percent.
3. Has remarkable early strength and strengthening effects on the concrete, and improve the strength by 20 to 60 percent.
4. Improve the workability of the concrete and comprehensively improve the physical and chemical properties of the concrete.
5. Adapt to various cements well, and is well compatible with other types of 0s.
6. Particularly applicable to the following concrete projects: Flowing concrete, plasticized concrete, steam-cured concrete, impermeable concrete, waterproof concrete, naturally-cured precast member concrete, reinforcing steel bars and prestressed reinforced concrete, high-strength and ultra-high-strength concrete.
Mixing Amount Range (Recommended)
