Concrete Admixture Dispersant Sodium Naphthalene Sulfonate Powder Product Description:
Naphthalene series water reducing agent is a non - induced water - reducing agent.The chemical name naphthalene sulfonate formaldehyde condensate, which has a strong dispersive effect on cement particles.For preparation flow state of concrete, early strength, high strength requirement of cast-in-situ concrete and pre-cast component, have very good use effect, can improve and improve concrete performance, widely used in roads, Bridges, tunnels, DAMS, ports, electricity, water conservancy and civil engineering, pipe and natural curing to the system components, etc.

Usage:
1. Produces the high slump flowing concrete with no loss in strength.Produces low water/cement ratio concrete with high strengths.
3. Ideal for using in high strength concrete, flowing concrete, early strength concrete, precast steam curing concrete, prestressed concrete etc. where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
3. Be used as basic material to produce others compound admixtures, (such as accelerating and water-reducing admixture, retarding and water-reducing admixture, pumping antifreeze and pumping water-reducing admixture, etc.)
Properites:
1. Appearance: Light brown powder& dark brown liquid. Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
2. Remarkable Plasticity: As a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 17-25% when it is admixed with reinforced concrete at 0.5-1.0%. Statistically, compression strength on the lst day, the 3 rd day and the 28 th day after single application is increased by 60-95% and 25-50% respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength, buckling strength and modulus of elasticity will be improved to some extent.
3. Improve miscibility of concrete amalgamator with water and collapsibility as well. As a condition of equivalent blending, collapsibility can be increased 4-7 times when it is added at 0.7% blend dosage.
4. 15-18% of cement can be reserved when the agent is blended at 0.7% blend dosage, which is preconditioned by same collapsibility and strength.
Dosage:
According to the type of cement, the temperature of the water, the ratio of water to cement ratio, the injection part and the spraying process, the quality requirements are determined, and the recommended dosage is 0.5-2.0%.
Our Advantages:
SNF produces high slump flowable concrete with no loss in strength.
SNF produces low water/cement ratio concrete and therefore, high strengths.
SNF in prestress/precast work, can be used to substantially reduce or eliminate the high energy requirements of external heat for accelerated curing.
SNF concrete, even at high slump, exhibits no significant segregation in comparison to concrete without a super-plasticizer at the same slump.
SNF aids in rapid discharge of concrete from truck mixers thereby reducing on the job time and improving mixer utilization.
