SLICK–PAK Improves the Workability of Concrete Pump
Slick-Pak is a dry powdered and patented polymer-based concrete pump primer which works as a lubricating agent for pipe and hose. Packaged in a patented, ready-to-use, water-soluble bag, it is uniquely formulated to provide the concrete pumper with a cost-effective replacement for premium priced grout, primer slurries or bagged cement primers. It also functions as a concrete pumping aid by reducing line pressure which enables the placement of hard to pump mixes and increases the range of pumpability.
Besides these, it is environmentally safe and contains no bentonite, cementitious materials, soaps or air entraining agents. It eliminates problems associated with the use of bentonite or similar materials for pump priming. Additionally, it reduces wear on equipment when starting a job.
Currently, it is being used worldwide and become the standard for priming concrete pumps.

Slick-Pak contains water thickeners and lubricating agents. As it goes through the pipes and hoses, it leaves a coat of water and lubricating agents and effectively wets all surfaces. As concrete comes behind the Slick-Pak, it does not lose water and the lubrication allows it to slip through the pipe.
It is compatible with all conventional concrete materials and can also be used as any standard concrete pumping aid. As a pumping aid, Slick-Pak should be added at a dosage of 1 to 3 bags per load of concrete. It may be added directly to the ready-mix concrete and should be mixed for 5 to 7 minutes to ensure that the material is uniformly dispersed. It will also have no deleterious effects on the structural integrity of the concrete.
It should be noted that Slick-Pak requires water to hydrate and when it is made with too little water, it will absorb water from the concrete in order to hydrate. Concrete with super plasticizers tends to have a low water content, so if the Slick-Pak absorbs any water from the plasticized concrete, it will have a tendency to plug. For priming concrete with super plasticizers, it is recommended to increase the amount of water used to prepare the priming solution.
