Sulfonated Acetone-formaldehyde Condensate, aka, Aliphatic Superplasticizer (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, and JIS-6204.
Applications
1. Used for projects which require high performance concrete with property of high strength, elasticity, fluidity, and impermeability:
(1)Rapid-transit railroad, Highway, Subway, Tunnel, Bridge.
(2) Self-compacting concrete.
(3) High-rise buildings with high durability.
(4) Pre-cast & Pre-stressed elements.
(5) Ocean oil drilling platform, Off-shore & marine structures etc.
2. SAF is especially applicable to following types of concrete: flowable and plastic concrete, autotrophic or steam curing concrete, impermeable and water proof concrete, durable and anti-freeze/thaw concrete, anti-sulphonate-corrosion concrete, steel-bar enforced concrete, and pre-stress concrete.
3. Used to make high strength concrete pipe (PHC) C80, ready-mix concrete (C20-C70), pumping concrete, high performance concrete, self-compacting concrete, water-proofing and large volume concrete.
4. Used in all kinds of Portland cements and steam curing concrete.
