Super Slump Buster FAQ

Category: Specialty

Q. What is Super Slump Buster?

A. It is a water thickener.

Q. How does Super Slump Buster work?

A. 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.

Q. Does Super Slump Buster work the same in all mixes?

A. 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.

Q. Does Super Slump Buster increase the strength of concrete?

A. No. Whatever amount of water was used in the mix does not change, so strength is not increased.

Q. What standards does Super Slump Buster meet?

A. Super Slump Buster falls in the category of Viscosity Modifying Admixtures (VMA). At present there are no ASTM standards for this group of materials.

Q. Does Super Slump Buster affect set time?

A. No.

Q. Does it affect air entrainment?

A. No.

Q. What are the best applications for Super Slump Buster?

A. 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.

Q. What is the mixing procedure of Super Slump Buster when adding to the concrete?

A. We 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.

Q. How long has Super Slump Buster been in the market?

A. Super Slump Buster has been sold since 1994.

Q. Can I use Super Slump Buster to pour concrete on an incline?

A. Yes.

Q. Can I pour concrete for flatwork first and then add Super Slump Buster to the same load to pour a curb of slip forming?

A. Yes.

Q. What is the maximum reduction in slump I can achieve using Super Slump Buster?

A. 3 to 4 inches.
