AK h5>
Descripción h4>
La resina de acetona-formaldehído (AK) es una clase de sustancia activa superficial macromolecular aniónica que se deriva de acetona, formaldehído y agente sulfonante con catálisis alcalina. AK es un reductor de agua de alto rango, comúnmente referido como un superplastificante. AK no contiene cloruro añadido.
Cumplimiento de estándares h4>
AK cumple con ASTM C494, tipo F estándar para reductor de agua de alta gama.

Applications
- Used for projects such as skyscrapers, wide bridge, ocean oil drilling platform, which requires high performance concrete with property of high strength, elasticity, fluidity, and impermeability.
- AK 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.
- Used to make high strength concrete pipe (PHC) C80, ready mixed concrete (C20-C70), pumping concrete, high performance concrete, self-compacting concrete, water-proofing and large volume concrete.
- Used in all kinds of Portland cements and steam curing concrete.
Features and Benefits
- AK is alkalescent and has a high water reducing rate of 15-25%.
- When it’s added, 25-30% of cement can be saved without sacrificing strength and slump loss compared with plain concrete.
- AK has significant early and post-strengthening ability. Concrete added with AK 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.
- AK has high plasticity. Concrete added with AK has less slump loss. It almost has no slump loss in 60 minutes and only loses 10-20% in 90 minutes.
- AK is applicable to a variety of cement. It improves workability and plasticity. It works well with other admixtures.
- AK can improve anti-freeze/thaw ability and impermeability of concrete. It protects concrete from sulphonate corrosion and improves physical performance in many other aspects.
- AK is nontoxic, nonflammable and noncorrosive to steel bars.
- AK effectively reduces the reaction with alkaline aggregates and has no crystallization from sodium sulphate in winter.
