blasting process of limestone for cement

Portland-Limestone Cement: An Important Step Toward Zero

In portland cement, which can contain up to 5% interground limestone, the clinker content is around 90% of the finished cement. Blended cements can include fly ash or natural pozzolans (Type IP), ground granulated blast furnace slag (Type IS), limestone between 5 and 15% (Type IL), and other additions.

In addition to pure limestone, Hooton and his team have also tested other potential cement clinker replacements for use in concrete. One of these is a substance known as blast furnace slag, a waste product of the iron and steel industry, which can be mixed with either Portland cement and Portland-limestone cement at levels of up to 75 per cent.

Limestone Extraction Without Drilling and Blasting | Agg-Net

For years, the limestone was extracted by drilling and blasting and then wet processed into clinker in the cement plant. In a move to increase productivity and reduce costs, IFCEM became the first cement plant in the Ukraine to initiate the transition from the wet process to a dry process, a measure that optimized the mining method for material
