sulfonated acetone-formaldehyde(SAF)
Description
The sulfonated acetone-formaldehyde condensate(SAF), 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.
Applications
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.

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
concrete.
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
approach.
Packaging, transport and storage
1. The product is packed in poly woven bag with plastic lines at 25kg.
2.Handle with care to avoid breakage when moving. Keep from moisture when transporting. This product is non-toxic, non-
irritating, no-combustible.
3. The powder form absorb moisture easily. It should be stored in its unopened packaging, please be store dry at usual
ambient temperature and protect from excessive heat.(below 40℃).Don't stack up too high. 1 year for powder form.
