MasterRheobuild 2000PF

Superplasticiser for high performance concrete and as a dispersing agent for MasterRoc microcements for ground injection

DESCRIPTION

MasterRheobuild 2000PF is an admixture containing multifunctional, water soluble sulphonated polymers of various chemical composition, thus specifically affecting the different mineralogical components of cement.

When MasterRheobuild 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 amongst the cement grains making their dispersion in water easier and consequently the mix more flowable. The action of MasterRheobuild 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.

CEMENT INJECTION

MasterRheobuild 2000PF has been found to be particularly beneficial in dispersing the MasterRoc microcements to allow enhanced penetration properties. In these applications MasterRheobuild 2000PF should be dosed at 1.5 – 2% on cement weight, with a water/cement ratio of 1. This will provide a stable mixture able to penetrate the finest groundmass cracks.

MasterRoc micro cement injection
