Effect of Grinding on Physico-Mechanical Properties

The resistance to permeability was also higher in concrete specimens cast using micro-silica ground for 6 h as a partial replacement for cement. So, it is inferred from the results that for an optimum grinding period of 6 h, ultra-fine micro-silica can be obtained.

Silica Dust Containment for Grinding and Cutting

Crystalline Silica is a common mineral, found in quartz, sand, gravel, clay, granite and other forms of rocks. OSHA reports that over 2 million people are exposed to silica dust at work. These particulates are released during cutting, grinding, drilling, and chipping of natural and manufactured stone products and during similar concrete work.
