The high-shear colloidal mill is recognized as the most efficient method of mixing bentonite, cement, fly ash, etc., with water. The intense mixing action results in homogeneous and stable mixes. Colloidally-mixed cementitious products are found to better resist bleed and provide higher compressive strengths than comparable materials prepared in lower energy, paddle-type mixers.
VortiMix is Simem’s new line of advanced high-shear colloidal mixers. The VortiMix can rapidly mix cementitious grouts as low as 0.5:1 water:cement ratio (by weight). When combined with an optional paddle assist, VortiMix can handle grouts as low as 0.45:1 w:c ratio, making the mixer ideal for lightweight cellular concrete applications. Hydrated bentonite can also be rapidly prepared in the VortiMix yielding improved gel strengths and reduced hydration times.
