Structuro 520R is differentiated from conventional superplasticisers 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 an electrocstatic dispersion occurs but the presence of the lateral chains, linked to the polymer backbone, generate a steric hindrance which stabilises the cement particle’s capacity to separate and disperse. This mechanism considerably reduces the water demand in flowable concrete.Get in touch Request a quote
Structuro 520R combines the properties of water reduction and workability retention. It allows the production of high performance concrete and/or concrete with high workability.
Structuro 520R is a particularly strong hyperplasticiser allowing production of consistent concrete properties around the required dosage.
- Increased early and ultimate compressive strengths

- Improved adhesion to reinforcing and stressing steel
- Improved resistance to carbonation
- Lower permeability
- Increased resistance to aggressive atmospheric conditions
- Reduced shrinkage and creep
- Increased durability
