Water reducing admixture are capable of reducing the amount of water used for mixing, and keeping the concrete slump substantially unchanged. But do you know why we use concrete water reducer? In order to improve the technical and economic benefits when preparing concrete, adding a small amount of water reducing agent can improve the performance of concrete, save the amount of cement used, so it has attracted widespread attention at home and abroad.
The functions of concrete water reducing agents
As a kind of concrete admixture, the functions of concrete water reducing agents can be summarized as follows:
- They can reduce the unit water consumption of concrete mixing without affecting the workability of concrete, thereby reducing the water-cement ratio and effectively improving the strength of concrete.
- The water reducing agents do not reduce the performance of the concrete mixture except the unit water consumption, can significantly change the workability of the concrete mixture, reduce the construction energy consumption, and facilitate the construction.
- They reduce the strength of concrete mixture, reduce the hardening time of concrete, and reduce the amount of cement per unit of concrete, thereby saving cement and reducing costs.
Most of water reducing admixtures belong to anionic surfactants, such as sodium lignosulphonate, sodium naphthalene sulfonate formaldehyde, polycarboxylate superplasticizer,etc. After adding the concrete mixture, they have a dispersion effect on the cement particles, which can improve its workability, reduce the unit water consumption, improve the fluidity of the concrete mixture, or reduce the amount of cement used.
Various Types of Water Reducing Admixtures for Sale
1. Sodium Lignosulphonate
Sodium lignosulphonate is a common type of water reducing agent, which can be used directly or as a raw material for composite admixtures. Because of its low price, it is widely used in mortar to improve workability, fluidity, and strength, and the water reduction rate is 8%-10%.
2. Naphthalene Based Superplasticizer
Kingsun naphthalene based superplasticizer(sodium naphthalene sulfonate)is a high range water reducer, and it is a product in which naphthalene is sulfonated by sulfuric acid and then condensed with formaldehyde. The appearance of naphthalene sulfonate superplasticizercan 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. What’s more, the water reduction rate is up to 25%.
3. Polycarboxylate Based Superplasticizer
Kingsun polycarboxylate superplasticizer is a kind of concrete superplasticizer which is the most advanced in the world, has the highest technology content, the best application prospect and the best comprehensive performance. It is a compound product of a carboxylic acid graft multi-component copolymer and other effective auxiliary agents. Compared with the performance of similar products at home and abroad, the polycarboxylic acid superplasticizer has reached the international advanced level in terms of technical performance index and cost performance.
