### Cement Grinding Optimization

· There are efficiency factors for dry grinding, open circuit ball milling, mill diameter, oversize feed, grinding finer than 75 microns and too large or too small reduction ratios. For cement appliion, the dry grinding (EF1), mill diameter (EF3), oversize feed (EF4) and fine product (EF5) factors are relevant.

### Concrete – Official Minecraft Wiki

Concrete is a solid block available in the 16 regular dye colors. Concrete requires a pickaxe to be mined. When mined without a pickaxe, it drops nothing. Concrete is formed when concrete powder comes into contact with a block of water (source block, flowing or waterlogged). It is not formed by contact with rain, filled cauldrons or water bottles. The bright and solid colors of concrete .
