HY330-50 is an innovative latest generation superplasticizer based on polycarboxylic ether polymers, and is specially engineered for ready-mix concrete. HY330-50 is differentiated from conventional superplasticizers, such as those based on sulphonated naphthalene formaldehyde condensate in that it is based on a unique carboxylic ether polymer with long lateral chains. This greatly improves cement dispersion. At the start of the mixing process the same electrostatic dispersion occurs but the presence of the lateral chains, linked to the polymer backbone, generate a steric hindrance which stabilizes the cement particles capacity to separate and disperse. This mechanism provides flowable concrete with greatly reduced water demand and extended workability. The material is based on Vinyl polyethylene glycol(GPEG). the effect of cement additive:  Lubrication: The polarity of the hydrophilic group in the superplasticizer is very strong, so the adso…
