Environmental Protection Concrete Additive Naphthalene Based Superplasticizer High Water Reducing Rate

      Environmental Protection Concrete Additive Naphthalene Based Superplasticizer High Water Reducing Rate

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.

1. 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%. 

2. This product is non-toxic and non-corrosive, but it is forbidden to eat. If it is inadvertent, such as in the eyes or in the mouth, please rinse it with water immediately;

3. When used in combination with other admixtures, the compatibility test should be carried out;

 It 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.

Product advantages

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: the water reducing rate is 14 ≤ 25%, the flowability of the mixture can be increased, and the slump of concrete can reach 15 ≤ 22 cm; The 60min loss of retarding superplasticizer is less than 50mm, which can delay the setting time of concrete by 2 ≤ 15h. through the test, the content can be increased and the length can be extended, and the strength of concrete can be improved in the later stage. When required, it is put forward that it is suitable for the continuous pouring of mass coagulation soil in hot season, which can reduce the hydration and heat release, reduce the temperature stress of concrete and avoid the occurrence of temperature difference cracks. Early strength superplasticizer: improve the early strength of concrete, frost resistance and other properties.

5. It has a strong dispersion effect on cement, and obviously improves the mixture and ease of operation, so that the concrete mixture is easy to pour and vibrate.

6, save cement, when maintaining the same strength, can reduce the amount of cement by 10-20%.

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

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.
