MasterRoc MS 685
A lubricating aid, viscosity modifying agent (VMA) and strength enhancer for concrete
How does MasterRoc MS 685 work?
MasterRoc MS 685 is a liquid admixture based on a suspension of amorphous silica.
These ultra-fine particles start working as soon as they are incorporated in the mix. The texture of the slurry is similar to cement paste and creates a stable microscopic mineral
This texture provides improved cohesion
, lessens porosity
and increases “compactness
” of the mix.
What is MasterRoc MS 685 used for?
MasterRoc MS 685 is suitable for pump concrete; semi-dry concrete mixes; mixes exposed to high friction; concrete exposed to frequent wetting; concrete with fine architectural finishes; high Performance concretes; shotcrete concrete; injection mortars; self-compacting concrete and improved flexural strength
What are the benefits of MasterRoc MS 685?
The amorphous silica starts working in a pozzolanic manner as soon as it is incorporated in the cement based mix and as a consequence gives texture to the paste.
This enhanced texture improves the whole rheology
of the concrete mix
) and prevents migration of the water
- Improves Cohesion
- Reduces pump pressures
- Reduces the tendency for a mix to segregate
- Reduces porosity
- Improves the overall quality of the concrete
- Corrects a lack of fine elements within a grading curve.
- Improves surface finish
