Certain concrete mixes designed for use in slip-form machines require a very tight mix to ensure the concrete doesn’t slump too much as it is extruded. While this may not seem like a big issue, controlling the slump of concrete can be difficult due to a range of factors. For this reason, keeping slump change products, like viscosity modifying admixtures is recommended. And Fritz-Pak’s Super Slump Buster is one of the best-rated viscosity modifying agents on the market.

Using Viscosity Modifying Admixtures

Viscosity modifying admixtures contain water-thickening chemicals. When these chemicals mix with the concrete, they thicken the water by suspending the cement particles. The thickened water holds the aggregates in in place and reduces the slump of the concrete mix. When using Super Slump Buster alongside air entrainers, dose each admixture separately.

Challenges of Viscosity Modifying Admixtures

Not all concrete mixes are compatible with viscosity modifying admixtures. Products such as Super Slump Buster becomes less efficient when the concrete mix includes a lower cement content, gap grades, or low aggregate-sand ratio. These types of mixes tend to slump differently than more traditional mixes so it can be difficult to know how to properly dose them with a viscosity modifying agent.

What is Super Slump Buster?
It is a water thickener.
How does Super Slump Buster work?
As the water thickens, it is able to maintain particles in suspension better than just plain water. So the thickened water holds the cement, the cement paste holds the sand, and the sand holds the aggregates, thus reducing slump.
Does Super Slump Buster work the same in all mixes?
No. In mixes with low cement content, Super Slump Buster is less effective. Also gapgraded mixes slump differently than properly graded mixes. Reverse mixes (i.e. low aggregate, high sand content) also slump differently.
Does Super Slump Buster increase the strength of concrete?
No. Whatever amount of water was used in the mix does not change, so strength is not increased.
What standards does Super Slump Buster meet?
Super Slump Buster falls in the category of Viscosity Modifying Admixtures (VMA). At present there are no ASTM standards for this group of materials.
Does Super Slump Buster affect set time?
No.
Does it affect air entrainment?
No.
What are the best applications for Super Slump Buster?
Super Slump Buster is most commonly used in slipforming or curb mixes. Normally these mixes require a low slump. Low slump concrete is difficult to batch because just a small amount of excess water can increase the slump. So adding Super Slump Buster can easily correct the slump.
What is the mixing procedure of Super Slump Buster when adding to the concrete?
e recommend 5 minutes of mixing at high speed to insure good dispersion throughout the concrete and then an additional 5 minutes at slow speed to allow for Super Slump Buster to develop its full thickening properties.
How long has Super Slump Buster been in the market?
Super Slump Buster has been sold since 1994.
Can I use Super Slump Buster to pour concrete on an incline?
Yes.
Can I pour concrete for flatwork first and then add Super Slump Buster to the same load to pour a curb of slip forming?
Yes.
What is the maximum reduction in slump I can achieve using Super Slump Buster?
3 to 4 inches.
  • Permits controlled slump reduction
  • Allows concrete placement on inclines
  • Excellent for forming curbs
  • Permits placing different flows from the same load
  • Minimizes segregation
  • Does not change water-cement ratio
  • Allows for maximum truck utilization
  • Faster discharge of concrete from trucks
  • Improves finishing characteristics
  • Easier placement of concrete in slip-form machines

Compatibility

Super Slump Buster is compatible with all air-entraining admixtures as well as other conventional admixtures. When used with other admixtures, each one must be dispensed separately into the mix.
