Alternate Of Limestone For Manufacturing Cement

2021-10-11 Cement manufacturing is the source of 5% of global carbon dioxide (CO2) emissions. The cement industry is a natural producer of CO2: 60% of emissions are due to the transformation of raw materials at high temperatures (decarbonation of limestone), 40% result from the combustion needed to heat the cement kilns to 1500°C.

Raw materials for cement manufacturing

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.

Understanding Limestone in Cement Concrete

2015-3-26  The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation ...
