Concrete Hiperplasticizers-Plastit® SPCA100

Plastit SPCA100 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 electrocstatic dispersion occurs but the presence of the lateral chains, linked to the polymer backbone. Generate a steric hindrance which stabilizes the cement particle’s capacity to separate and disperse. This mechanism considerably reduces the water demand in flowable concrete. Plastit SPCA100 is a particularly strong hyperplasticiser allowing production of consistent concrete properties around the required dosage

- Increased early compressive strengths
 Increased flexural strength
 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

Plastit SPCA100 is a high performance hyperplasticiser intended for applications where increased early compressive strengths are required, and it has been developed for use in
Self compacting concrete
 Concreting in cold weather
 Pumped concrete
 High performance concrete
 Per-cast concrete

The optimum dosage Plastit SPCA100 to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is between 0.4 to 1.2 kg/100 kg of cementitious material
