A colloidal mixer, Iske said, is the best way to ensure that every particle is completely and uniformly wetted during mixing for correct consistency.
In addition to its Cemix high-speed, high-sheer colloidal mixer and Cemag agitation tank, the Unigrout Smart A includes a Dosac control panel, two grout pump options and a Logac monitoring and logging unit.
The cement and fly ash are premeasured and pre-mixed and delivered to the job site in 1,000 pound "super sacks." The grout components (full sacks) are introduced into the Colloidal Mixer
which uses a high shear pump and baffles to recirculate and thoroughly mix the constituents, which is done for eight to 10 minutes.
