BRD Sodium Naphthalene Sulfonate Formaldehyde Superplasticizer SNF Powder FDN /Water Reducing Agent High Range Water Reducing

CAS No.: 36290-04-7

Naphthalene formaldehyde sulphonate water reducing agent is a β-Naphthalenesulfonic acid formaldehyde condensate, high purity, excellent performance, is a good comprehensive performance of concrete high efficiency admixture, it has high dispersibility, high water reduction, can save the amount of engineering cement, mixed with this product, It can greatly improve the mobility of concrete, improve slump, improve and ease, and can greatly improve the strength of coagulation soil, early strength, remarkable strengthening effect, no corrosion to steel bars, and good adaptation to all kinds of cement.it has the properties of high range water reduction , set retarding and excellent strengthening.

PRODUCT CHARACTERISTICSL

1. This product is non-toxic, non-flammable, stable in shape and has no rusting effect on steel bar. 

2, the gas content is 2.0 ≤ 4.0%, which is beneficial to pumping construction. 

3, the content of NF ≤ AIII sodium sulfate is less than 18%, and the alkali content is low, which will not cause alkali aggregate reaction. 

4. standard superplasticizer: water reducing rate 14 ≤ 25%, concrete slump up to 15 × 22 cm, retarding superplasticizer: 60min loss ≤ 50 mm, concrete bonding time can be delayed by 2 × 15 h, the content can be increased and the length can be increased, and there is a special need to improve the strength of concrete at the later stage. When seeking, in the pre-sales service, it is suitable for continuous casting of large volume of concrete in hot season, lower hydration heat release, lower temperature stress of concrete, and avoid the generation of temperature difference crack; and early-strong and high-efficiency water-reducing agent: to mention early strength and anti-freezing performance of concrete.

5. It has strong dispersing effect on the cement, and obviously improves the mix and workability, so that the concrete mixture can be easily poured and easy to vibrate. 

6. Save cement, and reduce cement consumption by 1020%while maintaining the same strength. 

7. Increase the compactness of concrete, reduce shrinkage and creep, improve the durability of concrete and extend the service life of concrete. 

High Water Reducing Rate Concrete admixture

$550.00 - $1,000.00 / Metric Tons | 1 Metric Ton/Metric Tons (Min. Order)

BRD Quick Setting Accelerator Powder Concrete Admixture

$260.00 - $560.00 / Tons | 1 Ton/Tons (Min. Order)

BRD Superplasticizer High Strength Polycarboxylate Concrete Admixture High Speed Railway

$2,000.00 - $3,600.00 / Tons | 1 Ton/Tons (Min. Order)

Naphthalene superplasticizer is suitable for concrete and mass concrete, cast-in-place pile, sliding form construction concrete, pumping concrete, concrete and so on under the condition of hot temperature. Configure C15-C50 all grades of concrete. It can be configured as retarding and early strength superplasticizer.

1.The powder is 0.8 ≤ 2% and the liquid is 1.5 ≤ 3.0%. 

2.According to the engineering requirements, the dosage can be adjusted after the test. 

3.It is generally added to the mixer at the same time as the mixing water. If the lag admixture or concrete is added before pouring, the effect of mixing and plasticizing is the best.

4. In order to ensure the best use effect, it is suggested that the user should determine the optimum content and method according to the specific situation of the project before using this product for the first time or changing the cement variety in the project.
