Super Slump Buster


SKU: 97180 Category:

Concrete curb mixes require a tight mix to ensure the curb doesn’t lose shape as it sets. Unfortunately, controlling the slump of concrete can be very challenging. That’s why keep a viscosity modifying admixture in the cab of your truck. And Fritz-Pak’s Super Slump Buster is super easy to add to the mix at the job site – so you can be sure you have the right slump for the job.

How Does Our Viscosity Modifying Admixture Work?

Super Slump Buster contains a powdered water-thickener. When it mixes with the water in the concrete, it suspends the cement particles in the mix. The suspended particles thicken the water, which then holds the aggregates in place, keeping the mix from slumping too much. This viscosity modifying admixture is compatible with air entrainers in the mix, provided they are dosed separately.

Benefits of Super Slump Buster

  • Permits controlled slump reduction
  • Allows concrete placement on inclines
  • Permits different flows from the same load
  • Improves finishing characteristics
  • Faster discharge of concrete from trucks
  • Easy placement in concrete slip-form machines

When to Use a Viscosity Modifying Admixture?

The general use of a viscosity modifying admixture is for curbing and slip-forming extruding, but not every mix is compatible with these types of admixtures. Fritz-Pak’s Super Slump Buster is significantly less effective in concrete mixes with lower cement content. Gap grade mixes and concrete with a low aggregate, high sand design tend to slump differently than more traditional mixes. Super Slump Buster will likely not perform as well in these types of mixes.
