Businesses that expose people to those chemicals must give clear and reasonable warning to the people being exposed. The law requires a warning for chromium if exposure would create a 1 in 100,000 risk of contracting cancer. The Air Quality Management District estimated the chromium levels near the cement plant were up to 50 times that amount.
Health effects. Cement can cause ill health by skin contact, eye contact, or inhalation. Risk of injury depends on duration and level of exposure and individual sensitivity. Hazardous materials in wet concrete and mortar include: alkaline compounds such as lime (calcium oxide) that are corrosive to human tissue.

We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thouh of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength. The Wonder Cement factory process is now complete.
High-pressure grinding rollers (HPGR) During the high-pressure comminution process, rather than being crushed between the roller surfaces, individual grains or particles are in effect compacted to a dense flake through exposure to relatively high pressures. Following de-agglomeration, the flake normally shows a substantial amount of completed or incipient …
