Jun 18, 2020 · Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kiln.

Jan 05, 2012 · Cement production adds around 4% or 5% of manmade CO2 to the atmosphere globally (in the US, cement manufacture adds about 1% of CO2). This is a big problem, and many efforts are underway to come up with cements that produce less CO2 than Portland (regular) cement. However, this amount is not as bad as it first appears, as I try to explain below.
