Slick-Pak 2 (Concrete Primer and Pumping Aid) |
| USE |
| Similar in composition to Slick-Pak but with higher amounts of thickening and
lubricating agents to help in pumping harsh mixes, lean concrete, lightweight concrete
and flowable fill. It can be used as a fluid loss additive when grouting into sandy soils. |
| ADVANTAGES |
- Increases ease and range of pumpability.
- Decreases wear on equipment.
- Decreases horsepower required for pumping.
- Reduces friction and line pressure.
- Improves mobility and consolidation.
- Minimizes slump and air loss through pump lines.
- Reduces dewatering of concrete.
- Slick-Pak II is packaged in ready-to-use water soluble
Fritz-Pak inner bags for convenient use at the plant or job site.

| DESCRIPTION |
| Slick-Pak II is a dry powdered concrete pumping aid packaged in a patented,
ready-to-use, water soluble bag. Slick-Pak II is uniquely formulated to provide
the concrete pumper with a cost effective method for improving the pumpability of
hard to pump and/or harsh concrete and grout mixes. Additionally, Slick-Pak II
reduces line pressure, improves fl ow properties and increases the rate and range
of pumpability. |
| Slick-Pak II does not contain calcium chloride, nitrates, nitrites or other potentially
corrosive materials and is compatible with all standard concrete admixtures. In addition,
Slick-Pak II contains no bentonite, cementitious materials, soaps, or air
entraining agents. |
| COMPATIBILITY |
| Slick-Pak II is compatible with all standard concrete materials as well as other
concrete admixtures. When used with other admixtures, each one must be dispensed separately
into the mix. |
| Slick-Pak 2 FAQ's: |
| Q. How does Slick-Pak II work? |
| A. It contains water thickeners and lubricating agents. As Slick-Pak II goes through the pipes and hoses it leaves a coat of water and lubricating agents and effectively wets all surfaces. As the concrete comes behind the Slick-Pak II it does not lose water and the lubrication allows it to slip through the pipe. |
| Q. What is the difference between Slick-Pak and Slick-Pak II? |
| A. Both products have water thickeners and lubricating agents. Slick-Pak has a higher proportion of lubricating agents than Slick-Pak II, thus it is better used as a pump primer. Slick- Pak II has a higher proportion of thickeners, thus it is better suited as a pumping aid, as well as being an excellent pump primer |
| Q. Does Slick-Pak II have fluid loss properties? |
| A. Yes. The thickeners used in Slick-Pak II work as fluid loss additives in the concrete. |
| Q. If I have a long run of hose or pipe, should I increase the Slick-Pak II concentration to make it more effective? |
| A. No. A too-high concentration may thicken the concrete excessively and produce a plug in the line. It is better to increase the volume of Slick-Pak II used to insure complete coverage and wetting of the line. |
| Q. What is the best way to prime horizontal lines? |
| A. Slick-Pak II will tend to run on the lower part of the line, it is recommended to use a rubber ball in front of the priming solution to avoid only wetting the bottom of the line. |
| Q. Why do I get plugs when priming for concrete with superplasticizers? |
| A. Slick-Pak II requires water to hydrate, so when Slick-Pak II is made with too little water it will absorb water from the concrete in order to hydrate. Concrete with superplasticizers tends to have a low water content, so if the Slick-Pak II absorbs any water from the plasticized concrete, it will have a tendency to plug. For priming for concrete with superplasticizers, we recommend increasing water content be used to prepare the priming solution. |
| Q. If I do not have a bucket available, can I prepare the priming solution in the hopper? |
| A. Yes. Most operators do it that way. Be sure that the bag dissolves completely by directing the water stream over it. |
| Q. How long in advance do I need to prepare my priming solution? |
| A. You need at least 5-10 minutes for the product to dissolve. Once it dissolves, it will stay stable for several hours, so you can prepare your priming solution well before the concrete arrives. |
| Q. Will it build-up in the pump pipes and hoses? |
| A. No. |
| Q. Can Slick-Pak II be added directly into the Ready Mix truck? |
| A. Yes. It will make the concrete more pumpable. |
| Q. Does Slick-Pak II contain bentonite clay? |
| A. No. Slick-Pak II does not contain bentonite or any other type of clay. |
