RHEOBUILD® 2000PF 

RHEOBUILD® 2000PF is an admixture containing multifunctional, water soluble sulphonated polymers of various chemical compostition, thus specifically affecting the different mineralogical components of cement. When RHEOBUILD® 2000PF is added to concrete the molecules of the polymer, having a negative charge, absorb onto the surface of the cement grains. This causes an electrostatic repulsion to occur amoungs the cement grains making their dispersion in water easier and consequently the mix more flowable. The action of RHEOBUILD® 2000PF occurs even when Portland cement clinker is mixed with other materials (e.g. pozzolans, fly ash, slags & microsilica) in the production of blended cements.
