DMA Floors - Slab and Mix Design

Curing compounds can slow the initial grinding process. Floor flatness should be FF50 (ASTM E1155-96). FF levels below 50 can show an inconsistent reflection, aggregate exposure, and sheen as can be seen in the photo below. Integral colors can be effective in areas that will receive high amounts of UV exposure.

Lapping and Polishing Basics - South Bay Tech

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can
