◆ When the concrete strength and slump are basically the same, the cement consumption can be reduced by 10-25%
◆ It has a significant early strength and enhancement effect on concrete, and its strength is increased by 20-60%.
◆ Improve the workability of concrete and comprehensively improve the physical and mechanical properties of concrete.
◆ It has good adaptability to various cements and is well compatible with other types of concrete admixtures

Sodium Naphthalene Sulfonate Formaldehyde(SNF-A) for Water reducing agent
Sodium Naphthalene Sulfonate Formaldehyde(SNF-A) for mortar
Polycarboxylate Superplasticizer Powder-PCE Powder Widely used in highways, bridges, dams, ports, tunnels, electric power, water conservancy and industrial and civil construction projects, steam curing and natural curing prefabricated components. Widely used in precast & ready- mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc.Suitable for preparation of early- strength, high-strength, high-anti-filtration and self sealing&pumpable concrete.
5. Guidelines for Use
When using porous aggregate, Sodium Naphthalene Sulfonate Formaldehyde(SNF-A) is advisable to add water and stir first, and then add water reducing agent. When the slump is large, it should be noted that the vibrating time is not too long to prevent bleeding and stratification
6. Package and Storage
Package: 40kg plastic bags with PP liner. Alternative package may be available upon request. Storage: Shelf-life time is 2 years if kept in cool,dried place.Test should be done after expiration.
