Concrete Hiperplasticizers-Plastit® SPC435

Plastit SPC435 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 SPC435 combines the properties of water reduction and workability retention. It allows the production of high performance concrete and/or concrete with high workability. Plastit SPC435 is a particularly strong hyperplasticiser allowing production of consistent concrete properties around the required dosage

Increased early and ultimate 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 SPC435 is a high performance hyperplasticiser intended for applications where increased early and ultimate compressive strengths are required, and it has been developed for use in 
 Self compacting concrete
  Pumped concrete 
 High performance concrete
 Per-cast concrete

The optimum dosage Plastit SPC435 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 1.0 kg/100 kg of cementitious material
