Calcination occurs when limestone, which is made of calcium carbonate, is heated, breaking down into calcium oxide and CO2. This process accounts for ~50 percent of all emissions from cement production. Indirect emissions are produced by burning fossil fuels to heat the kiln.

Low/NegativeGHG Cement Back to Manufacturing The production of cement, a key ingredient in the concrete that forms the basis of much of our infrastructure, is responsible for about 5% of global greenhouse gas emissions, half from the energy used to power it and half from the carbon dioxide released during the conversion process itself.
Cement is a very useful binding material in construction. The applications of cement over various fields of construction have made it a very important civil engineering material.. Some of the numerous functions of cement are given below. It is used in mortar for plastering, masonry work, pointing, etc.; It is used for making joints for drains and pipes.

Today, concrete block manufacturing is a highly automated process that can produce up to 2,000 blocks per hour. Raw Materials The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel.
Type IV (Low heat cement) This type of cement is used in mass concreting because it generates less heat, though sets slowly but becomes much stronger after curing. Its design strength is 90 days. Applications of Type IV Cements. It is used where the rate and amount of heat generated from hydration must be minimized.
