Grinding aids for high performance cements

Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].

Improving cement grinding - GCPAT

The majority of CO 2 produced during cement manufacture arises during clinker production due to the calcination of calcium carbonate fossil fuel burning and electricity consumption (mostly for grinding). Using a base CO 2 factor of 862kg CO 2 /t clinker each one percent drop in clinker in cement can reduce emitted CO 2 by 8-9kg/t cement.

OSHA Rules on Silica Dust Exposure from Concrete Cutting

The Occupational Safety and Health Administration has recently passed a final ruling to curb the detrimental effects of breathing in silica dust created from cutting and grinding materials like concrete and stone. The targeted inflictions include lung cancer silicosis chronic obstructive pulmonary disease (COPD) and kidney disease.

Cement mill - Wikipedia

From 1885 onward the development of specialized steel led to the development of new forms of grinding equipment and from this point onward the typical fineness of cement began a steady rise. The progressive reduction in the proportion of larger un-reactive cement particles has been partially responsible for the fourfold increase in the strength of Portland cement during the twentieth century. [2]
