Concrete Grinding Contractor: Choosing The Right One

Concrete grinding diamonds are available in a wide variety of shapes, sizes, and strengths. Size is classified by the mesh or grit number, although a large diamond has a small number (18/20), while a smaller diamond has a larger number (80/100 or 170/200, for example). While larger diamonds are used to expose the aggregate, smaller diamonds will hone or polish your surface. A 30/40 grit is a

Cement mill Wikipedia

The emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material. Because of this, cement continued to be ground very coarsely (typically 20% over 100 μm particle diameter) until better grinding technology became available. Besides producing un-reactive cement with slow strength growth
