plastic spc100- Polycarboxylate base superplasticizer

High Range Water Reducing Admixture, Based on Polycarboxylate

Plastit SPC100 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 SPC100 combines the properties of water reduction and workability retention. It allows the production of high performance concrete and/or concrete with high workability. Plastit SPC100 is a particularly strong hyperplasticiser allowing production of consistent concrete properties around the required dosage. Plastit SPC100 is suitable for concrete with water-cement ratio is lower than 40%.
The optimum dosage of Plastit SPC100 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, including PFA, GGBFS and microsilica. 
Plastit SPC100 conforms with BS 5075 Part 3 and with ASTM C494 as Type A and Type F, depending on dosage used.
