Nano Concrete Grinding

Grinding and Polishing Concrete - Home - Newgrind

The chemical treatments are an exclusive Nano Technology blend that hardens the concrete, closes the pores and stops dusting and surface decay. The sealer also minimizes the intrusion of staining agents into the concrete. The 3 levels of finish are: Matte finish (stop at 100 grit HyperGloss Pad) Semi-Gloss (stop at 400 grit HyperGloss Pad) Gloss.

Nano-carbide slag seed as a new type accelerator for ...

Nano-carbide slag (nano-CS) seed was prepared by wet-grinding technique. Four dosages of nano-CS were considered, i.e. 0%, 1%, 3% and 5% of the cement mass. Setting times, hydration kinetics, microstructure and early-age compressive strength were investigated. The working mechanism of nano-CS in the accelerated cement hydration was also discussed.

What Are the Advantages of Wet Grinding vs. Dry Grinding?

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
