Product Description:

Sulfonated Acetone-formaldehyde

sulfonated acetone-formaldehyde(SAF)

Sulfonated Acetone-formaldehyde Construction Chemicals

The sulfonated acetone-formaldehyde condensateSAF, is a kind of anionic aliphatic macromolecular surface active 

substance which is derived from acetone, formaldehyde and sulfonating agent with alkalic catalysis.

SAF is a high range water reducer, commonly referred to as a superplasticizer. SAF contains no added chloride. SAF

 meets the requirements of chemical admixture specifications for concrete: ASTM C494, DS-5075, JIS-6204.


The powder is dissolved into 30-35% liquid to used as usual .  

Through the experiment to find the best dosage, compliance dosage is 1.5-2%.(liquid )

It joins together with the mixing water in concrete. Then after the addition it can also be used. The concrete mixed it.

As the water reducing rate of HSB is larger, before initial set time of concrete, the surface bleeds yellow pulp that is a normal 

phenomenon. Before the final setting of concrete or after the concrete on the strength, the color will disappear.With water 

conservation will be to make color fade faster, that do not affect the internal and surface properties of concrete.

Sulfonated Acetone-formaldehyde Construction Chemicals Features and Benefits
1. SAF is alkalescent and has a high water reducing rate of 15-25%.
2. When it’s added, 25-30% of cement can be saved without sacrificing strength and slump loss compared with plain 

3. SAF has significant early and post-strengthening ability. Concrete added with SAF can reach to 60-70%, 100% of 

designed strength in 3 and 7 days respectively. Thus its strength is enhanced by 30-40% compared with plain concrete in 

28 days.
4. SAF has high plasticity. Concrete added with SAF has less slump loss. It almost has no slump loss in 60 minutes and 

only loses 10-20% in 90 minutes.
5. SAF is applicable to a variety of cement. It improves workability and plasticity. It works well with other admixtures.
6. SAF can improve the anti-freeze/thaw ability, and impermeability of concrete. It protects concrete from sulphonate 

corrosion and improves physical performance in many other aspects.
7. SAF is nontoxic, nonflammable and noncorrosive to steel bars.
8. SAF effectively reduces the reaction with alkaline aggregates and has no crystallization from sodium sulphate in winter.
Uses and Dosages
1. Dosage range is 0.4-1.2% and the recommended dosage is 0.6% of the weight of cementitious materials. Appropriate 

blend dosage shall be determined according to the projects requirements and the materials used.
2. The effects of water reduction and dispersion will be better if applied with stagnant water blending method or post-blend
