For decades the method of drilling and blasting was used to extract the Limestone After that it used to be wet processed into clinker in the concrete plant But this process used to be extremely expensive So now the dry mining process is preferred for the production of the clinker as it minimizes the consumption of the fuel per ton of material

Limestones are of wide variety namely with differences in the process of formation mineralogical composition grain size and texture Such variability leads to differences in weathering characteristics and behaviour under different environmental conditions and applications Therefore detailed studies are mandatory to assess the main factors controlling the physical mechanical properties

• Carboniferous limestones are the major source of raw material in Britain The other main limestones are Cretaceous Chalk and Jurassic • Chalk is porous and often has high moisture content that leads it to its use in the semi dry/wet manufacturing process of making cement This particular process represents some 16% of total production Shale • Shale is a pure sedimentary rock
