Controlling concrete slump presents many challenges for the ready-mix driver. A variety of factors, including temperature, transportation, and air content, can cause fluctuations in the concrete slump. This means that the slump at the time of batching may or may not match the slump once the load arrives at the job site. Fortunately, Fritz-Pak’s Super Slump Buster offers the ability to lower the concrete slump at the job site, without changing the water-cement ratio. Super Slump Buster is a viscosity-modifying admixture containing water-thickening chemicals. When mixed into the concrete, these chemicals hold the aggregates closer together, thus decreasing the slump of the concrete and reducing the risk of segregation in the mix. Super Slump Buster comes packaged in our signature water-soluble bags, contains no hazardous materials, and works well in mixes placed via slip-form machines.

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.
Which states have approved this product through the Department of Transportation?
Arizona, Colorado, Idaho, Iowa, Kansas, Louisiana, Oklahoma, South Carolina, Tennessee, Vermont, & Virginia
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.
