PCE Concrete Polymer  Admixtures with Good Dispersibility Polycarboxylate

Polycarboxylate superplasticizer is the use of polyoxyethylene macromonomers, a new generation of polycarboxylate superplasticizer unsaturated acids and sulfonic acid by free radical polymerization of monomers. Products with high water reduction and low slump loss performance, to ensure concrete excellent work ability, high strength and excellent durability, it can be widely used in pumping concrete, self-compacting super fluid and High Performance concrete and concrete products.

Advantages

1. low dosage.

2.high water reducing rate.

3.low shrink rate.

4. improves the liquidity of concrete greatly.

5. keep long time construction performance, as well as ameliorates its peace ability and physics    performance, improving construction quality.

*Good dispensability, high water reduction rate, and excellent adaptability with kinds of cement.

*Because of its good powder fluidity, it is especially suitable to be used in dry-mixed mortar, wear resisting floor ground, self-flowing ground, grouting materials and so on.

*It has high reduction rate apply in gypsum and plaster. It can be used in gypsum plaster, gypsum products and gypsum based self-leveling floor etc. It will much increase the strength with gypsum produt.

Chemistry& Mechanism of Action

Conventional superplasticisers, such as those based on sulphonated melamine and naphthalene formaldehyde condensates, at the time of mixing, become absorbed onto the surface of the cement particles. This absorption takes place at a very early stage in the hydration process. The sulphonic groups of the polymer chains increase the negative charge on the surface of the cement particle and dispersion of the cement occurs by electrostatic repulsion. PC super-plasticizer is differentiated in that this unique polycarboxylate ether polymer with long lateral chains is tailored to generate a super slump retaining effect in combination with polycarboxylate ether and/or modified lingosulphonate based admixtures. This greatly improves cement dispersion and steric hindrance. At the start of the mixing process the same electrostatic dispersion occurs as described previously, but the presence of the lateral chains, linked to the polymer backbone, generates a steric hindrance which stabilizes the cement particles capacity to separate and disperse. This mechanism provides flowable concrete with greatly reduced water demand and aids in super slump retention.

Packing Detail: Because this concrete water reducer agent is a kind of liquid , in order to avoid the rain and debris into or moisture evaporation products, we choose the sealed barrels for packaging.

Delivery Details:About 7 days after your payment.
