The limestone is directly placed in the mill for grinding to obtain limestone fine powder. The fineness of limestone fine powder processed by the industrial dry mill is used. It can be up to 3000 mesh. Although it can't compare with the fineness of the wet mill, it is more than enough for the production of desulfurized lime.
The major environmental impact of concrete comes from the CO2 emissions, produced during the cement manufacturing process. The main goal of this research project is to evaluate the efficiency of limestone powder as a partial cement replacement, in order to reduce energy consumption and CO2 emissions. This study utilizes limestone powders, …
Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.
