Product Description
Yellow Brown Concrete Chemical Admixtures Naphthalene Superplasticizer
Product description:
Naphthalene formaldehyde sulphonate water reducing agent is a synthetic powder based onbeta-sulphonate formaldehyde ondensate and reactive polymer.
It has the properties of high range water reduction, set retarding and excellent strengthening.
Elt-nsf sodium sulfate is less than 10% , suitable to middle strength or high strength
concrete where high range water reduction is desired.
Product picture:
Application:
1. Water Reducing Agent: In the same water cement ratio, the initial slump concrete increased by more than 10 cm, water reducing rate can reach 15-25%
2. Early Strengh Agent: It has early strength and enhancing effect on concrete, and can increase the intensity of 20-60%.
3. Retarder: It can lengthen the time of concrete hydration hardening, make the fresh concrete can keep the plastic in a long time, and can adjust the setting time of fresh concrete.
4.Pumping Agent: It can improve the workability of concrete mixing, reduce bleeding rate and segregation performance, increase consistency, saving cement, improve the compressive strength, bending, tensile strength, and delay the rate of hydration heat, avoid cracking, improve the permeability resistance and durability.
5. Anti-freezing Agent: It can ensure that the concrete can be normal construction under the negative temperature, reduce the freezing point of the concrete mixing, make concrete hydrated under 0 ºC to 15 ºC negative temperature environment, reduce the freezing point, improve the early strength of concrete. It can be used in all kinds of concrete engineering, construction in cold season.
6. Others:
1. It can reduce the cement dosage of 10-25%.
2. It 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:0.5 - 1.5% by weight of cement. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.
SNF-C can be added directly or added in after dissolved in water. It can be added during mixing and after-mixing (better). The after-mixing approach can achieve better result.
Packing&Delivery:For powder: Woven plastic bag with film liner. Net weight: 25kg +/- 0.2 kg.
It should be stored in a dedicated warehouse that is well-ventilated and dry and keep
away from moisture.
Shelf Life: Minimum 12 months. After the expiration date, it can be used if testing results is qualified.
