Water reducing admixture is also called water reducing agent or water reducer. It is a concrete admixture that can reduce water consumption while the concrete slump is basically unchanged. As a concrete additive, water reducer for concrete plays a very important role in concrete applications. For example, the use of water-reducing admixtures can reduce the amount of water and increase the strength of concrete. Adding it can save cement consumption and reduce engineering costs.  According to water reduction and enhancement capacity, it is divided into the ordinary water-reducing agent and high range water reducer.

Types of Water Reducing Admixtures in KINGSUN

KINGSUN is one of the leading construction chemical manufacturers and suppliers in China. We also have focused on researching and producing concrete admixtures with high quality for many years. There are three types of water-reducing admixtures for sale in KINGSUN, they are sodium lignosulfonate, sodium naphthalene sulfonate, and polycarboxylate superplasticizer. If you would like to know their price or some other information, please feel free to contact us. Here are some introduction to the three types.

  • Sodium Lignosulphonate
  • Sodium Naphthalene Sulfonate
  • Polycarboxylate Superplasticizer

Sodium lignosulphonate is a common water reducer in concrete and its raw material is lignin. It can be used in a mortar to improve the workability, fluidity, and strength of concrete. The water reduction rate of sodium lignosulphonate is between 5% and 10%. Sodium lignosulphonate has three functions. They are namely dispersion, venting, and initial hydration inhibition. There are three uses of sodium lignosulphonate. Firstly, it can reduce water consumption and increase the strength of cement. Second, it can improve the workability and fluidity of the concrete while maintaining the same amount of water and strength. Thirdly, it can reduce the amount of cement used and the amount of water used to maintain the same strength.

Sodium naphthalene sulfonate (SNF) is the earliest high range water reducing admixture used in China. It is a product of naphthalene sulfonation by sulfuric acid and condensation with formaldehyde and is an anionic surfactant. The appearance of naphthalene type concrete water reducers could be light yellow to dark brown powder depending on the product. It is easily soluble in water and has good dispersion effect on many powder materials such as cement. The water reduction rate of SNF can reach 25 percent. Different water-reducing agents have different characteristics.

The main characteristics of sodium naphthalene sulfonate are as follows:

  • When the strength and slump are basically the same, the amount of cement can reduce by 10% to 25%.
  • When the water-cement ratio is constant, the initial slump of concrete can increase by more than ten centimeters, and the water reduction rate can reach 15% to 25 percent.
  • It has a significant early strength and enhancement effect, and its strength can increase by 20-60%.
  • It can improve the workability of concrete, adapt to various types of cement. Moreover, it is compatible with other types of concrete admixtures.
  • Particularly suitable for use in the following concrete works: fluid concrete, plasticized concrete, steamed concrete, impervious concrete, waterproof concrete, natural curing precast concrete, steel and prestressed reinforced concrete, high strength ultra high strength concrete.

Polycarboxylate based superplasticizer (PCE) is the most advanced high range water reducing admixture in the world because it has the highest technological content, the best application prospect, and the best comprehensive performance. Compared with the performance of similar products at home and abroad, the polycarboxylate high range water reducer admixture has reached the international advanced level in terms of technical performance index and cost performance. Polycarboxylate superplasticizer is a new type of superplasticizer with unique performance and no pollution. In general, it is an ideal admixture for high-performance concrete.
