The Vortimix high-shear colloidal mixer is recognized as the most efficient method of mixing bentonite, cement, fly ash, and slag with water. The intense mixing action results in homogeneous and stable mixes. Colloidally mixed cementitious products are found to better resist bleed (separation and settlement of solids) and provide higher compressive strengths in comparison to materials prepared in lower-energy type mixers.
VortiMix is an advanced high-shear colloidal mixer by Simem. The VortiMix can rapidly mix cementitious grouts as low as 0.45:1 water:cement ratio (by weight). Hydrated bentonite mixes are rapidly prepared in the VortiMix, which yield improved gel strengths and reduced hydration times for applications where pre-hydrated bentonite is necessary.
Recirculation “ports” allow mixture to re-enter mixing vessel with velocity, causing turbulent material flow. An automated pinch-valve network determines GROUT mixture route. Pinch-valve actuation allows mixture to recirculate then discharges GROUT for storage and pumping, which allows a quick removal after completing the job
